Different "BoxBlur" Algorithms

Im trying out some different ‘boxblur’ algorithims, but specifically, to blur surface normals on surfaces. I have had good luck with this one:

The problem is, most of the rest different algorithims are built into libraries specifically for images (they do the image-> num conversion). Any one have access to this kind of data logic? I.E. different techniques on sorting into blur boxes.


If the question is : Is there blurring method for 3d geometry ? The answer is yes. There are many

There are methods in Dendro … and many others.
You can apply the pixel method on voxel with 3d matrix …

Absolutely, the Monte-Carlo looks very interesting.
