[Insight-users] fastest way to get image voxels(pixels) within an itkMesh ?

[Dan Mueller]

Hi Greg,

You could try rasterizing your mesh, then iterating over the image
considering only values under the raster mask. Further, you could
constrict the iteration to the bounding box of the raster mask. If
your mesh consists of triangles, you can use
itkTriangleMeshToImageFilter to create a binary image mask.

If rasterizing the mesh is already too slow, I'm not sure what else
you could do...

Some more information regarding your specific problem might also help
discover solutions "outside the box".

Hope this helps.

Regards, Dan
