This is GPU-parallel implementation of Marching Cubes using Vulkan. It builds using CMake, and you can run it via:
./vulkan_marching_cubes <volume_file.raw> <isovalue> [optional output.obj]
The program takes volumes whose file names are formatted like those found on OpenScivisDatasets, you can download datasets from that page to try out the app. For example, you can compute the isosurface at isovalue = 80 on the skull and output the mesh to an OBJ file:
./vulkan_marching_cubes skull_256x256x256_uint8.raw 80 skull_iso_80.obj
