MarchingCasesA
vtk-examples/Cxx/VisualizationAlgorithms/MarchingCasesA
Description¶
Marching cubes cases for 3D isosurface generation. The 256 possible cases have been reduced to 15 cases using symmetry. Red vertices are greater than the selected isosurface value.
This example runs the example MarchingCases with the arguments 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14.

Download and Build MarchingCasesA¶
Click here to download MarchingCasesA and its CMakeLists.txt file. Once the tarball MarchingCasesA.tar has been downloaded and extracted,
cd MarchingCasesA/build
If VTK is installed:
cmake ..
If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..
Build the project:
make
and run it:
./MarchingCasesA
WINDOWS USERS
Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
