Hello
I am not sure if a GA version could make it much quicker, but I would be very interested (for nice deep learning application) to have an efficient way to compute partial volume in a 3D grid from a surface (triangular meshes)
It is a pure geometric problem, simple at first look but very long to compute
see Surface to 3D partial volume for more detail
I recently find an other implementation from this paper
https://arxiv.org/pdf/2101.08511.pdf
again the execution time is around 10 mn for a 200^3 grid, which makes it difficult to use for training a deep neural network
I would be glad to collaborate, if you are interested
