Hi. I'm trying to do some kind of perlin noise (1 or 2 octaves max) in ARB_VP (not Cg!). I've searched the net for some ideas but I found only 2 partly useful examples. One on nVidia's dev pages that uses table look-up and uses way to many instructions and another on opengl.org forums that uses hashing function. I've translated it to ARB_VP and it seams it only works for small input values. So if anyone has (working) example of VP(ARB_VP, NV_VP, (DX)VS) perlin noise I would realy like to see it. ps: Should I post this in OpenGL forum? You should never let your fears become the boundaries of your dreams. [edited by - _DarkWIng_ on November 27, 2003 6:41:12 AM]

I''m not really sure about that, but if i remember correct there is a demo around which uses vertex programs for generating noise for terrain rendering. I don''t remember if it actually do that (generate noise in the vp) but i think so.

I think this is the link: (I don''t know how to actually apply a link to this, so this is the address )

and this is the demo

Hope you find what you are searching.

I''ve saw that, but perlin noise is created on CPU and not in VP. Any other link?
