ParaView is an application framework as well as a turn-key application; Modeling software OpenFOAM and ParaView ; mesh processing: generation, manipulation, conversion

ParaView is an open source, multi-platform data analysis and visualization application. It has a client-server architecture to facilitate remote visualization of datasets

It is an application built on top of the Visualization Tool Kit (VTK) libraries.

The ParaView code base is designed in such a way that all of its components can be reused to quickly develop vertical applications. This flexibility allows ParaView developers to quickly develop applications.

Input/Output and File Format

  • Supports a variety of file formats including: VTK (new and legacy, all types including parallel, ascii and binary, can read and written).
  • Various polygonal file formats including STL and BYU (by default, read only, other VTK writers can be added by writing XML description).
  • Many other file formats are supported. See ParaView Readers and ParaView Writers for a full list.

CMake is a family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice. ParaView utilizes CMake for the software compilation process.


ParaView is used as the visualization platform for the Modeling software OpenFOAM (Open Field Operation and Manipulation).It is primarily a C++ toolbox for the customisation and extension of numerical solvers for continuum mechanics problems, including computational fluid dynamics (CFD). It comes with a growing collection of pre-written solvers applicable to a wide range of problems.

First major general-purpose CFD package to use polyhedral cells. This functionality is a natural consequence of the hierarchical description of simulation objects.

OpenFOAM compares favourably with the capabilities of most leading general-purpose commercial closed-source CFD packages. It relies on the user’s choice of third party pre- and post-processing utilities, and ships with:

  • a plugin (paraFoam) for visualisation of solution data and meshes in ParaView.
  • a wide range of mesh converters allowing import from a number of leading commercial packages
  • an automatic hexahedral mesher to mesh engineering configurations

OpenFOAM was conceived as a continuum mechanics platform but is ideal for building multi-physics simulations.

OpenCFD develop OpenFOAM in the Linux/UNIX operating system because: we believe it is the best platform for this kind of high end simulation code development and operation; Linux is efficient, robust, reliable and flexible and undergoes rapid development and improvement; Linux is open source, like OpenFOAM; Linux is very effective for parallel operation on Beowulf clusters.

OpenFOAM is open source software so people can freely compile it on any operating system they choose. Most OpenFOAM users are running Linux, so this site offers the download of binaries for selected Linux systems.

As the present time we are unaware of any binary distributions for Windows or MacOSX. However, ports to these operating systems have been the subject of debate on the OpenFOAM discussion site, which may provide the best source of information on the matter.

OpenFOAM uses finite volume numerics to solve systems of partial differential equations ascribed on any 3D unstructured mesh of polyhedral cells.

Mesh generation

OpenFOAM applications handle unstructured meshes of mixed polyhedra with any number of faces: hexahedra, tetrahedra, degenerate cells, basically anything.

Mesh generation is made simple by the fact that a cell is simply represented as a list of faces and a face as a list of vertices: this makes mesh handling very easy even for complex meshes with, say, embedded refinement or complex shapes near the boundary.

OpenFOAM is supplied with the following mesh generator tools that run in parallel.

Mesh generation tools

blockMesh A multi-block mesh generator
extrude2DMesh Takes 2D mesh (all faces 2 points only, no front and back faces) and creates a 3D mesh by extruding with specified thickness
extrudeMesh Extrude mesh from existing patch (by default outwards facing normals; optional flips faces) or from patch read from file
snappyHexMesh Automatic split hex mesher. Refines and snaps to surface

The main mesh generators cover two extremes: snappyHexMesh, that can mesh to complex CAD surfaces; blockMesh a simple file-driven block mesh generator.

Mesh manipulation

OpenFOAM is supplied with several utilties that perform mesh checking and manipulation. The full list of utilties is given below

Mesh manipulation

attachMesh Attach topologically detached mesh using prescribed mesh modifiers
autoPatch Divides external faces into patches based on (user supplied) feature angle
cellSet Selects a cell set through a dictionary
checkMesh Checks validity of a mesh
createBaffles Makes internal faces into boundary faces. Does not duplicate points, unlike mergeOrSplitBaffles
createPatch Utility to create patches out of selected boundary faces. Faces come either from existing patches or from a faceSet
deformedGeom Deforms a polyMesh using a displacement field U and a scaling factor supplied as an argument
faceSet Selects a face set through a dictionary
flattenMesh Flattens the front and back planes of a 2D cartesian mesh
insideCells Picks up cells with cell centre ’inside’ of surface. Requires surface to be closed and singly connected
mergeMeshes Merge two meshes
mergeOrSplitBaffles Detects faces that share points (baffles). Either merge them or duplicate the points
mirrorMesh Mirrors a mesh around a given plane
moveDynamicMesh Mesh motion and topological mesh changes utility
moveEngineMesh Solver for moving meshes for engine calculations.
moveMesh Solver for moving meshes
objToVTK Read obj line (not surface!) file and convert into vtk
pointSet Selects a point set through a dictionary
refineMesh Utility to refine cells in multiple directions
renumberMesh Renumbers the cell list in order to reduce the bandwidth, reading and renumbering all fields from all the time directories
rotateMesh Rotates the mesh and fields from the direcion n1   \special {t4ht= to the direction n2   \special {t4ht=
setSet Manipulate a cell/face/point set interactively
setsToZones Add pointZones/faceZones/cellZones to the mesh from similar named pointSets/faceSets/cellSets
splitMesh Splits mesh by making internal faces external. Uses attachDetach
splitMeshRegions Splits mesh into multiple regions
stitchMesh ’Stitches’ a mesh
subsetMesh Selects a section of mesh based on a cellSet
transformPoints Transforms the mesh points in the polyMesh directory according to the translate, rotate and scale options
zipUpMesh Reads in a mesh with hanging vertices and zips up the cells to guarantee that all polyhedral cells of valid shape are closed

Mesh motion

OpenFOAM adopts a novel approach to mesh motion by defining it in terms of the boundary motion which is extremely robust.

The solver need only define the the motion of the boundary and everything else will be done automatically. The open architecture of OpenFOAM solver codes allows quick and efficient implementation: mesh motion can be based on any solution variable, either local or integrated and by dynamically adjusted during the run.

Mesh motion is also transparently integrated with top-level models: the model writer does not see the additional complexity, which is conveniently packaged within the discretisation operators.

For examples of automated mesh motion in OpenFOAM, see Solutions

Mesh conversion

OpenFOAM accepts meshes generated by any of the major mesh generators and CAD systems. Listed below are converter utlities for the major commercial mesh generators. Note that it is also possible to import the meshes from most general purpose mesh generators since they will export in a format read by one of the converters.

Available Algorithms

The algorithms below are ready to be downloaded. They are generally written in JAVA or in ANSI-C, either by students or by the members of the Biomedical Imaging Group.Please contact the author of the algorithms if you have a specific question.
JAVA: Plug-ins for ImageJ
JAVA classes are usually meant to be integrated into the public-domain software ImageJ.
bullet Drop Shape Analysis. New method based on B-spline snakes (active contours) for measuring high-accuracy contact angles of sessile drops.
bullet Extended Depth of Focus. The extended depth of focus is a image-processing method to obtain in focus microscopic images of 3D objects and organisms. We freely provide a software as a plugin of ImageJ to produce this in-focus image and the corresponding height map of z-stack images.
bullet Fractional spline wavelet transform. This JAVA package computes the fractional spline wavelet transform of a signal or an image and its inverse.
bullet Image Differentials. This JAVA class for ImageJ implements 6 operations based on the spatial differentiation of an image. It computes the pixel-wise gradient, Laplacian, and Hessian. The class exports public methods for horizontal and vertical gradient and Hessian operations (for those programmers who wish to use them in their own code).
bullet MosaicJ. This JAVA class for ImageJ performs the assembly of a mosaic of overlapping individual images, or tiles. It provides a semi-automated solution where the initial rough positioning of the tiles must be performed by the user, and where the final delicate adjustments are performed by the plugin.
bullet NeuronJ. This Java class for ImageJ was developed to facilitate the tracing and quantification of neurites in two-dimensional (2D) fluorescence microscopy images. The tracing is done interactively based on the specification of end points; the optimal path is determined on the fly from the optimization of a cost function using Dijkstra’s shortest-path algorithm. The procedure also takes advantage of an improved ridge detector implemented by means of a steerable filterbank.
bullet PixFRET. The ImageJ plug-in PixFRET allows to visualize the FRET between two partners in a cell or in a cell population by computing pixel by pixel the images of a sample acquired in three channels.
bullet Point Picker. This JAVA class for ImageJ allows the user to pick some points in an image and to save the list of pixel coordinates as a text file. It is also possible to read back the text file so as to restore the display of the coordinates.
bullet Resize. This ImageJ plugin changes the size of an image to any dimension using either interpolation, or least-squares approximation.
bullet SheppLogan. The purpose of this ImageJ plugin is to generate sampled versions of the Shepp-Logan phantom. Their size can be tuned.
bullet Snakuscule. The purpose of this ImageJ plugin is to detect circular bright blobs in images and to quantify them. It allows one to keep record of their location and size.
bullet SpotTracker Single particle tracking over noisy images sequence. SpotTracker is a robust and fast computational procedure for tracking fluorescent markers in time-lapse microscopy. The algorithm is optimized for finding the time-trajectory of single particles in very noisy image sequences. The optimal trajectory of the particle is extracted by applying a dynamic programming optimization procedure.
bullet StackReg. This JAVA class for ImageJ performs the recursive registration (alignment) of a stack of images, so that each slice acts as template for the next one. This plugin requires that TurboReg is installed.
bullet Steerable feature detectors. This ImageJ plugin implements a series of optimized contour and ridge detectors. The filters are steerable and are based on the optimization of a Canny-like criterion. They have a better orientation selectivity than the classical gradient or Hessian-based detectors.
bullet TurboReg. This JAVA class for ImageJ performs the registration (alignment) of two images. The registration criterion is least-squares. The geometric deformation model can be translational, conformal, affine, and bilinear.
bullet UnwarpJ. This JAVA class for ImageJ performs the elastic registration (alignment) of two images. The registration criterion includes a vector-spline regularization term to constrain the deformation to be physically realistic. The deformation model is made of cubic splines, which ensures smoothness and versatility.
Most often, the ANSI-C pieces of code are not a complete program, but rather an element in a library of routines.
bullet Affine transformation. This ANSI-C routine performs an affine transformation on an image or a volume. It proceeds by resampling a continuous spline model.
bullet Registration. This ANSI-C routine performs the registration (alignment) of two images or two volumes. The criterion is least-squares. The geometric deformation model can be translational, rotational, and affine.
bullet Shifted linear interpolation. This ANSI-C program illustrates how to perform shifted linear interpolation.
bullet Spline interpolation. This ANSI-C program illustrates how to perform spline interpolation, including the computation of the so-called spline coefficients.
bullet Spline pyramids. This software package implements the basic REDUCE and EXPAND operators for the reduction and enlargement of signals and images by factors of two based on polynomial spline representation of the signal.
bullet E-splines. A Mathematica package is made available for the symbolic computation of exponential spline related quantities: B-splines, Gram sequence, Green function, and localization filter.
bullet Fractional spline wavelet transform. A MATLAB package is available for computing the fractional spline wavelet transform of a signal or an image and its inverse.
bullet Fractional spline and fractals. A MATLAB package is available for computing the fractional smoothing spline estimator of a signal and for generating fBms (fractional Brownian motion). This spline estimator provides the minimum mean squares error reconstruction of a fBm (or 1/f-type signal) corrupted by additive noise.
bullet Hex-splines : a novel spline family for hexagonal lattices. A Maple 7.0 worksheet is available for obtaining the analytical formula of any hex-spline (any order, regular, non-regular, derivatives, and so on).
bullet MLTL deconvolution : This Matlab package implements the MultiLevel Thresholded Landweber (MLTL) algorithm, an accelerated version of the TL algorithm that was specifically developped for deconvolution problems with a wavelet-domain regularization.
bullet OWT SURE-LET Denoising : This Matlab package implements the interscale orthonormal wavelet thresholding algorithm based on the SURE-LET (Stein’s Unbiased Risk Estimate/Linear Expansion of Thresholds) principle.
bullet WSPM : Wavelet-based statistical parametric mapping, a toolbox for SPM that incorporates powerful wavelet processing and spatial domain statistical testing for the analysis of fMRI data.

First place all of your slices into a 3-d matrix. This will give you a cube of data. You can then view it from multiple planes by using this format variable(:,:,a) where a is the slice position in a direction directly into your displayed image. Using the same format you can display other planes variable(:,a,:). Converting your image to greyscale will allow you to display it using implay.

I’m sure that since you are working with MRI you have access to the image processing toolbox.

While viewing images in a plane where the pixels are not square you need to scale your image. (if you have a 3x3x5 voxel and display the 3×5 pixel representation) Also remember your slice separation if you don’t have 3-d k-space.

I’m not sure what you mean by ‘model,’ but you can combine 2D images together to form a 3D image by using the cat(3, slice1, slice2, slice3, slice4, slice5,……) function.

3D: What’s New in Google SketchUp 7.1? (sept2009)

What’s New in Google SketchUp 7

Fast and reliable

We’ve made SketchUp even more intuitive, added tools for power users, and made it easier to find and share models with the world.

We’ve made SketchUp easier to use.
With edges that automatically break other edges where they cross, objects that are smart enough to know how they should behave when you interact with them, and drawing hints that are clearer and more consistent, Google SketchUp 7 is the most intuitive SketchUp ever.

It’s all about collaboration and sharing.
In SketchUp 7, you can search for models in the Google 3D Warehouse right from the Component browser, take credit for what you contribute, keep track of your collaborators, and generally bask in the glow of knowing you’re part of the worldwide 3D community.

PRO There’s even more in SketchUp Pro.
LayOut is officially out of beta and ready to go. LayOut 2 is faster, more reliable and includes vector rendering, improved text handling and more. SketchUp Pro power users can also create Dynamic Components: models that animate, scale and replicate intelligently.

Learn more about LayOut 2 and Dynamic Components in Google SketchUp Pro 7 »

SketchUp 7: More intuitive and more powerful

Break edges

New! In 7.1: Improved support for large models
We overhauled SketchUp’s rendering engine to make it easier to work with big models. With the right setup, operations like orbiting, zooming and drawing can be quicker and smoother in 7.1.

Break edges

Crossing lines break automatically
When you draw a line that crosses another line on the same plane, both lines are split where they meet. Most folks think this is how SketchUp should have worked from the start. Well, now it does. Say goodbye to tracing over edges to make them split.

Dynamic scale

Scale without stretching
New Dynamic Components are special: they’re programmed to know what they are. When you use the Scale tool on a dynamic staircase, it automatically adds or removes steps as you make it bigger or smaller. No more stretching, no more distortion.

Custom Options

Configure objects with Component Options
Some Dynamic Components are hooked up to the new Component Options dialog box. Instead of breaking out the modeling tools to make a change, just choose options and watch the component reconfigure automatically. It’s modeling without the mess.

Interact tool

Introducing the Interact tool
Clicking things is fun – especially with the new Interact tool. Some Dynamic Components can perform animations, rotate, move, resize, change color or move to a scene in your model when you click on them with Interact.

Break edges

New! In 7.1: Photo Textures
Use Google Street View imagery to add real-world photo textures to your geo-located SketchUp models. Watch a video »

Break edges

New! In 7.1: Nearby models
Use the Component Browser to search the 3D Warehouse for buildings located near the one you’re working on, then download the ones you want directly into your model. No more hunting around to find the context you need. Watch a video »

Custom attributes

PRO Build components that know what they are
With Google SketchUp Pro 7, you can turn any component into a Dynamic Component. Endowing your models with behaviors like animation and smart scaling makes them easier for you and everyone else to use. If you can use a spreadsheet, you can build Dynamic Components.

Custom Attributes

PRO Custom attributes
Need to keep track of metadata like Part Number, Weight or Cost in your models? With SketchUp Pro 7, you can tag your models with luscious meaning and information to make them more useful and easier to carry forward in your workflow.Learn more about using Dynamic Components in Google SketchUp 7 »

SketchUp 7: Sharing and Collaboration

3D Warehouse search

Search the 3D Warehouse
We’ve added Google 3D Warehouse Search to the Component Browser, which gives you access to jillions of models (give or take a zillion) right inside SketchUp. You can also save particular searches as Favorites, making it easier to find stuff quickly later on.

Download locally

Download models locally
You can save anything you find on the 3D Warehouse to your local drive, making it easy to work even if you happen to be offline. Better yet, you can download models to local collections up to a dozen at a time.

Break edges

New! In 7.1: Direct Component upload
Upload individual components to the 3D Warehouse without first having to save them out to separate files. Split up large city models into buildings, preserve Dynamic Component functionality and more. Watch a video »


Take (and give) credit
Tag your models with your nickname so that people will know who built them no matter where they end up. And since Credits automatically keeps track of the stuff you use to build your own models, it’s easier than ever to give credit to your collaborators.


Custom Templates
You can include all of your organization’s proprietary Styles, Watermarks and components in a custom Template so that every member of your team has everything they need, right from the start. In SketchUp 7, saving custom templates is a breeze.

Break edges

New! In 7.1: Import and Export COLLADA files
COLLADA is a 3D file format based on open standards. The data you create is yours; it shouldn’t be locked inside a proprietary file type. COLLADA makes it easier to move your models between different pieces of software.

Break edges

New! In 7.1: Import and Export KMZ files
Google Earth KMZ is the standard file format for packaging 3D models together with information about their geographic locations. The newest version of SketchUp gives you access to a world of geo-located 3D models.

Generate Report

PRO Generate reports
Use the metadata embedded in your components to create tabular reports. In SketchUp Pro 7, you can export detailed lists of every named entity and their corresponding attributes in either HTML or CSV format, for use in your favorite spreadsheet application.


And that’s not all!
We improved the inferences to make them more visible and easier to use. There’s a new area of the Status bar that tells you more about your model. The VCB is now called Measurements, and you can change its location on your screen. You can make textures unique, and choose to edit them in the photo-editor of your choice. You can apply anti-aliasing to textures to make them look better from a distance. See the complete list of changes in SketchUp 7 »

PRO LayOut 2: Create professional presentation documents, fast

Break edges

New! In 7.1: Dimensions
Apply dimensions to scaled SketchUp models and vector graphics to create design documents and simple construction drawings with LayOut 2. Watch a video »

Break edges

New! In 7.1: Snap to SketchUp model
Elements like lines, labels and dimensions automatically snap to points in the SketchUp models you insert in LayOut 2. It’s a little bit like magic.

Vector rendering

Work bigger with Vector Rendering
LayOut 2 makes it easier to work with complex models and larger paper sizes. Switch to Vector Rendering when you want clean, resolution-independent drawings. If you want to tweak the line weights a bit, you can « explode » your model to vector edges and tweak it line by line.


Long live Measurements
You know the little text box in the lower-right corner of the SketchUp modeling window? The one you use to enter dimensions, angles and other stuff? Now you can key in numbers in LayOut just like you do in SketchUp. Be accurate to your heart’s content.


Curves are fun again
Its boring name notwithstanding, LayOut 2’s new-and-improved Line tool has superpowers. It’s simple and intuitive, and it incorporates everything you already love about SketchUp’s inference system. Try it and you’ll see — it’s like taking off your mittens to tie your shoes.

Break edges

New! In 7.1: Improved Freehand tool
Draw curves with LayOut 2’s Freehand tool and watch them turn into smooth, perfect vector lines that you can edit. It’s a more natural way to draw.

Editable Paths

Editable paths
Double click any shape in LayOut 2 to edit its control points. Drag any point onto an adjacent one to make the first one disappear. Hold down Ctrl (Option on a Mac) to add a point or make a smooth curve pointy. Reshape any curve fluidly by dragging its handles. Delicious, no?


Move, rotate and scale
We’ve completely redesigned LayOut’s geometric manipulators to be easier to use and to stay out of your way. You can move, scale and rotate anything on your page without changing tools, and the new « heads-up » display helps with accuracy as you work.

Image export

Export to images
Need JPEGs or PNGs of your pages? LayOut 2 includes direct export to these formats, which saves you from having to use another tool to rasterize your PDFs. We suggest using your extra time to do something for yourself. Maybe buy a hammock.

Group edit

In-place Group edit
Use the Select tool to double click a group to edit its contents. You can move, scale, rotate and copy/paste inside the group, then click outside to go back to the rest of your file. No more ungrouping and regrouping just to make a change.

Break edges

New! In 7.1: Lists
LayOut 2 makes it easy to include lists – bulleted or numbered – in your text.

Improved text

Improved Text
For LayOut 2, we’ve fixed problems and added some new functionality for text. You can now create both bounded (confined to a box) and unbounded text, depending on your need. Text can be aligned to top, bottom, left, right or center within its bounding box, both vertically and horizontally.

Break edges

New! In 7.1: Improved Grids
Being able to see your grid as dots instead of lines, behind or in front of your drawing, makes it easier to see what you’re doing. Hooray for clarity!

Break edges

New! In 7.1: Improved Copy/Paste
We’ve made it easier to move elements like graphics and text between LayOut 2 and the other programs in your design toolbox.


Right-click on any placed SketchUp model and choose Explode. Depending on how it was rendered, you’ll get vector lines, raster images, or a combination of both. It’s the easiest way to get vector geometry to edit directly, hands-down.


And that’s not all!
We made improvements to almost every corner of LayOut in its first non-Beta release: rectangle pick targets, styles handling, text editing, layer visibility, toolbars, presentation mode, overall stability, view performance, memory management — you name it, we made it better.Learn more about LayOut 2 »

PRO Style Builder: Make your own sketchy-edge Styles for SketchUp


Turn models into sketches
Showing a hand-drawn sketch does two things: It abstracts detail so you and your client can talk about what’s important, and it communicates that your concept is open for discussion. With Style Builder, you can create personalized sketchy Styles that tell the story of your design.


Brand your models
The Styles you create with Style Builder are completely unique. When you apply them to your models, you’ll have computer models that look like you made them. After thirty years of CAD, isn’t it about time everybody’s drawings stopped looking the same?


Use any medium at all
Your Styles can be based on any mark you make, in any medium. Marker, pencil, crayon, burnt stick, technical pen, ballpoint, gouache, smudgy finger, pen and ink, highlighter… You get the picture – anything.
