a Gabor noise node for OSL

OSL provides us with a fairly new noise alternative but this noise is not yet available as a node so I implemented a super simple one. You can read about on my blog.

The picture above could probably have been made with Perlin noise as well, but by varying the bandwidth, the number of impulses or the direction vector (in the anisotropic case) you can achieve effects that are definitely not achievable with Perlin noise or fBM noise. There are more nice qualities to this noise, there is a link in the blog article to the authors site.

I encourage people to experiment and if you have some interesting effect, please post it!

Created an overview of the parameters of Gabor noise with graphic examples:


Might be useful for people who wish to experiment.
