Sorry, but it's a massive png which I don't want to burden my poor server with.

lol, wait for the next release, I'll tell you more.

Actually this one could have been done without a shader, because it uses the identity texture coordinate mapping

nice renders though

Here is a test of procedural marble.

I got stymied when I tried to get more control over the noise. The div function had an error when I tried to divide two reals.

Code: Select all

Error: IndigoDriverExcep: SceneLoaderExcep: Builder: no function with signature div : real * real declared or defined.  (In element 'shader', around line 141, column 13)

Also it would be really, really nice to have a scale parameter for the noise functions.

Thanks Ono getting better and better.

Wow ono, that flower thing is awesome.

Oops yeah I commented out the div function.

As for scaling the noise: just multiply the position vector by a scalar before you pass it into the noise() function. Also try FBM, it gives nicer (more complex) noise than the simple noise() function.

Is it possible to "Warp" that pattern around FBM to get slight irregular deformations of the pattern?
