08 Feb 2013 Mesh voxelisation Voxelise a triangular-polygon mesh. Author: Adam A

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 Alonso,
The function tells you the path to the output .sat file, displaying it in the command window. Have you tried looking in that location?

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

I suspect the best way will be to rotate the STL before voxelisation, like you suggest. If you try to do it post-voxelisation by rotating the 3D grid then you'll need to do a lot of interpolating, which will be slow and could introduce errors or artifacts. As for parallel processing - I don't see any reason why it shouldn't work, but I haven't looked into it.

21 Jun 2013 Plot a 3D array using patch Plotting a 3D array using a patch surface mesh Author: Adam A Hassan

Great work Adam.
However, I get this error whenever I run your code on my data:

??? Undefined function or method 'PATCH_3Darray' for input arguments of type 'double'.

Any idea of why I am getting this error and what should I do to fix it?

Nay I know how can I create the voxelisation using 3D points(x,y,z) of on the surface only. The 3D points should be the vertices. But how can I get the normals. Hope to get some help

Hello Adam,

Thanks a lot. I can get a large size binary mask based on your comments.

Hello Adam,

Your code is great, but when I tried to voxelize with a bit large number of grids, (eg. 1000x1000x100), it generated out of memory error. Is there any way to get a binary mask at specific z-depth?

Thank you in advance.
