how can i get such noise / algorithm, osl, cycles

Hey there,

I am trying to get a procedural texture like you can see in the pictures below:



I think its somehow connected to this method: http://en.wikipedia.org/wiki/Lucas–Kanade_method
Any ideas? It would be really great to have some more procedural texture algorithms in cycles.

I found some more noisy alorithms on github and on blogspot. Is there another resource where i can download some shader code?

The method you refer to is an image analysis method, not so much a method to generate noise I think. The noise in your images does look interesting but it might be a simple as mapping Blender’s basic noise texture no only to color but use it as a height map as well.

Do you have a link to the original images? (maybe we can find out what the generating method was)

cheers,

it looks like the height maps Bryce makes (think they was fractal remember you could tile them )

Its done in c4d. The noise type is called Luka. Thats all Infos i have. I will have a look at Bryce. Here is the nearest i come with Blender sofar. Its a cloud texture with the voronoi algorithm.


It distinctly looks to me like, in the original shot, one texture is being used to modify another. For instance, a noise texture which is “sort-of being bump-mapped,” except that the pixels are being displaced in all three dimensions. It’s as though you’re using another texture to “sculpt a cloud.”
