Hi Yun-Ho Jang,

Yes, the code can be used to get a binary mask at a specified z-depth by specifying the required z-depth as the input gridZ. This works as long as gridZ is not an integer value. (By integer I do not mean in terms of datatype (int16, int32, int64, etc), I just mean in terms of being a whole number.)

However, if gridZ is an integer value then the code presumes that it defines the number of voxels in the grid in the z direction. To work around this, you could voxelise at two z-depths defined in gridZ (as a two-element vector), then discard the slice you don't want to leave you with a single binary layer. Not an elegant way to do it unfortunately, but this wasn't an anticipated use-case for the code when it was designed.

Hope this helps,
Adam

Hi Eff,
This code is designed for triangular-polygon meshes only, but your example mesh consists of quadrilateral faces.
Hope this helps,

I was looking for a way to convert 3d stl data into a volume and this function is great!
