Tutorial

About this page

This page contains materials for the VTK-m tutorial.

This tutorial will be presented on Sunday, October 20th at the VIS19 conference in Vancouver, Canada. Attendees can get the slides HERE and the user guide is HERE.

There are two options for running code:

1. Building VTK-m on your own machine. For more instructions click here.
2. Running our VirtualBox image with VTK-m installed. For more instructions click here.

Sections below describe how to pursue each of these options.

Download and build VTK-m

The process to build VTK-m:

• Download V1.5.0 here.
  • (note the build page assumes you will be accessing the master via a git clone, but we encourage you to use the released version for the tutorial)
• Do not enable the TBB, OpenMP or CUDA support, at least at first.
  • (we stand behind our support for these backends, but it is good to start simple)

In all, your process on Unix/Mac should be something like:

# (download VTK-m 1.5.0)
# tar xvfz vtk-m-v1.5.0.tar.gz
# mkdir build install # out of source build
# cd build
# cmake -DCMAKE_INSTALL_PREFIX=../install \
#       -DVTKm_ENABLE_TESTING:BOOL=OFF \
#       ../vtk-m-v1.5.0
# cmake --build . -j 4

The main instructions to download and build are here. That said, we recommend following the instructions above.

The process to build code examples:

• Download the examples for the tutorial [ here].

Your process on Unix/Mac should be something like:

# (downloads from above)
# export P=/path/where/you/want/to/place/tutorial/examples
# export D=/path/to/where/your/browser/downloads/files
# cp $D/VTKm_tutorial_examples.tar $P
# cd $P
# tar xvf VTKm_tutorial_examples.tar # places tutorial files in $PWD
# cmake . -DCMAKE_PREFIX_PATH="<path_to_vtkm-installation>/"
# cmake --build . 
# ./tut_io # run 1st example
# ls out_io.vtk # confirms 1st example successfully completed

Download Virtual Box image with VTK-m

The Virtual Box instance with VTK-m installed can be found here. VTK-m files can be accessed in the "/home/vtkm/Softwares/VTK-m/"

1. The `build` directory is where VTK-m is built using `CMake`.
2. The `install` directory is where VTK-m is installed.
