<br class="">
Is there any way to get a list containing the IDs of all voxels within a<br class="">
vtkImageStencilData?<br class="">
<br class="">
My method at the moment for getting all the voxels in the stencil is to<br class="">
create a vtkOBBTree and check if the centre of each voxel is inside the<br class="">
vtkPolyData related to the stencil, but this is very slow.<br class="">
<br class="">
Thanks in advance for any pointers,<br class="">
