OpenCL Volume Blur SOP
Added 2018-08-25 16:24:48 +0000 UTCApplies Gaussian blur to a volume.
Features:
1. It is orders of magnitude faster than the default Volume Blur SOP when significant number of iterations are used and OpenCL acceleration is turned on.
2. Min/Max Cut Off thresholds
3. Both OpenCL and C++ network branches.
4. No radius option by design. Using radius creates a large kernel to execute. It's much faster to use 3x3x3 kernel with many iterations that yields a much higher quality result. Using radius also reveals the cubic nature of the volumes as shown in the image above.
If you use the same number of iterations and turn off Radius option in the default Volume Blur, the results will match 100%.
