Overview
These shaders implement some useful procedural noises that are not readily available with the V-Ray supported version of OSL.
They all are 3D noises that use the shading point's position in object space rather than the surface's texture coordinates.
Use the shaders with a VRayOSLTex instance with the "wrap texture coordinates" option turned off.
The shader code can be found at alligatorNoise.zip.
Parameters
n - the n values for the red/green/blue wavelengths (f.e. 0.65, 0.55 and 0.45 micrometers).
k - the k values for the red/green/blue wavelengths
