ohif-step's Issues

GrowCutGenerator does not work for a single slice.

I've observed that GrowCut does not work for a single slice, the labelmap/strengthmaps do not change between iterations. I assume this is because the center is [x/2,y/2,0], and the latter coordinate means that no fragment in the shader pases this block:?

It must be a flooring issue, but I would expect the value in the shader to be 0.5 in the z direction for all voxels in the single frame sized texture any ideas @pieper?

Do we need a special 2D routine to deal with this edge case?
This is likely true for the core step library also.
