Some small tools I have written to speed up 3D voxel processing with CUDA, or parsing and writing 3D mesh.

vox2dem

A CUDA accelerated C++ tool to extract digital elevation models (i.e. heightmaps) from building voxels. link

voxRefactor

A CUDA accelerated C++ tool to dilate building voxels. link

gml2obj

A Python tool to extract individual buildings from CityGML files. link



(More messy code from course projects…)

CUDA conv

…with tiling and memory tricks on GPU. link
