Histogram-preserving Blending for Randomized Texture Tiling (aka Procedural stochastic texturing)

I have the first working version of the support for Brent Burley's "Histogram-preserving Blending for Randomized Texture Tiling" (aka Procedural stochastic texturing).
Given this image map:
A normal tiled rendering will look like:
While with randomized tiling:
Another example:
The support can be enabled by just setting the ".randomizedtiling.enable" property to 1:
Code: Select all
scene.textures.imgtex.file = pattern-3.jpg
scene.textures.imgtex.randomizedtiling.enable = 1
Quite amazing stuff !

OMFG!

Another strike in the right field. Well done Dade.

Good to see that you are still arround.

This is now available in the Blender addon, so you can play around with it. It's an option in the imagemap node.
Note that you will have to switch the device to CPU to use it, until GPU support is implemented.

That is fast thanks BYOB !

I have also yet to write single channel and check bump mapping support.

Good looking and a necessary addition.
BTW
Are there any plans for custom controls like U&V offset, rotation & scale, amount and type of blending?
Here's corona's version for example
