Pink noise with LIC

At the suggestion of Anne in the comments of a previous posting about line-integral convolution (LIC) algorithm for vector field visualization, I tried pink noise as the input texture map.

UPDATE 10/27/12: Apple seems to have removed templates, here is a […]

POV-Ray destination for IDL object graphics

I spent some time improving the POV-Ray destination for object graphics I talked about in a previous article. I can now produce visualizations of actual data (like the one on the right) using this destination and its related library of classes.
