VTK

VTK

The Visualization Toolkit (VTK)[1] is an open-source, freely available software system for 3D computer graphics, image processing, and visualization.

VTK in HPC

Example: NOVCA-Visualization [2] - NOVCA-Example

The execuatable "CreateGraph", which by complining using cmake, is executed to get the unstructured VTK file "testVertex.vtu" which is fed to ParaView to get the graph similar to "graphCXX.png".

CWRU HPC Specific Guide

VTK/Cxx

Request a compute node with Visualization Support. We recommend using Ondemand Desktop listed as one of the options at HPC Visual Guide.

Load the required VTK module:

module load cmake

module load VTK

Clone the Repository:

git clone https://github.com/sxg125/NOVCA-Visualization

Go to NOVCA-Visualization directory:

cd NOVCA-Visualization

Checkout the VTKCxx branch:

git checkout VTKCxx

Compile the Code:

mkdir buid

cd build

cmake ..

make

Run the Executable:

./CreateGraph

You will get the "testVertex.vtu" file which needs to be fed to the ParaView. Open the file in ParaView, apply glyph and get the one similar to graph "graphCXX.png" at [2].

VTK/Python

Request a compute node with Visualization Support. We recommend using Ondemand Desktop listed as one of the options at HPC Visual Guide.

Load the required modules including the VTK:

module load python

module load VTK

Clone the Repository:

git clone https://github.com/sxg125/NOVCA-Visualization

Go to NOVCA-Visualization directory:

cd NOVCA-Visualization

Run the script:

./paraviewGraph.py

You will get the "testVertex.vtu" file which needs to be fed to the ParaView. Open the file in ParaView, apply glyph and get the one similar to graph "graphCXX.png" at [2].
