export 3D scalar volume data from triangular surface model
Author
hello...
I have a triangular surface model...
i wan to make a algorithm in which i imaginary draw a grid in x , y and z direction ...these three grids make cubes...
i want to detect that if the vertex of triangle is in inside of the cube or not...
actually i want to export 3D scalar volume data from my triangular surface model...
for marching cube algorithm...
how can i do this...
much thanks in advance..

If I'm understanding you correctly, would something like what's being done in this chapter of GPU Gems 3 (search for the Voxelization section) be what you're looking for?
Hi Lucky,
I found this library which may help. I believe it uses the GPU hardware to perform the voxelization, and also handles "antialiasing" by determining whether a cell is "inside", "outside" or partially inside and outside at the same time.
