OpenCL Volume Sharpen SOP
Added 2018-07-22 19:50:37 +0000 UTCSharpens the voxels of a volume using the unsharp mask technique that enhances edges via a procedure that subtracts a blurred version of the volume from the original volume.
Features:
1. It is orders of magnitude faster than the default Volume Wrangle SOP when significant number of iterations are used and OpenCL acceleration is turned on.
2. Separate controls for blurring and sharpening iterations.
3. Min/Max Cut Off thresholds
4. Ability to use a mask volume to mask out the sharpening.
5. Both OpenCL and C++ network branches.
[Update] Volume Convolve SOP: Min/Max Cut Off thresholds
[Note] Volume Convolve SOP: Parallel execution of multiple OpenCL kernels is turned off in the For Loop network on purpose because by design Side Effects allows a single OpenCL kernel to be executed at any time, even though multiple kernels can actually be executed in parallel. If you turn on this option internally (Multithread when Compiled) it will create artifacts in the resulting volumes unless you are using the very latest builds of Houdini where this is recently fixed.
