simple displacement mapping on a sphere

in General Discussion • Other • 7 months ago

If I want to draw a sphere I just have to call sphere (100) and processing makes one.

There's little info on displacement mapping in processing (2 threads in this forum mostly) but all I've found involves drawing the sphere vertex by vertex manually.

Is there a way to do a simple displacement mapping of a sphere surface? I just want to add some noise so I can get a more "planetoid" look. Similar to what this is doing: http://vimeo.com/43377260

Only way I think you could perform displacement mapping is to use PShader with a GLSL displacement mapping shader that uses a texture for the displacement map. This could be a good start http://www.ozone3d.net/tutorials/vertex_displacement_mapping.php for you to work from.
