Marching Cubes algorithm implementation with DirectX / C++. Heavy lifting done on the geometry shader.
It's an old hobby project, the code could be way cleaner :)
For now the only way to use the program is to download the project, fix DirectX SDK paths if needed, run the project and observe the results.
- To change the precision of the resulting geometry, change the data size (height, depth, width) variables in the beginning of DirectXApp::setupVisualizationData().
- To change how the geometry is coloured, play with the variables that are named something related to colors in the geometry shader.
- To visualize different kinds of density data, select (comment/uncomment) one of the functions in the beginning of VolumetricData::CreateTestData(). The descriptions of the images below have the name of the function that was used to create the densities for that image in the parentheses.
Ugly gif of the thing live
A sphere which we've distorted with coherent 3d noise (used VolumetricData::createBumpySphere())
Only coherent 3d noise (used VolumetricData::createRandomNoise())
No noise, just a sphere (used VolumetricData::createSphere())
