Another post at real-time rendering

More interesting links posted at the real-time rendering blog.

The OpenGL 3.2 and GLSL 1.5 tutorial programs he mentions sound like they could be useful. I started to investigate the shader language part of OpenGL recently but didn't get very far. Using a gpu to speed up the drawing of computer graphics sounds like it could be useful thing to know. It seems the new features of OpenGL are encouraging that direction. At the least, I'm planning on reading the code for a phong shaded sphere at the tutorial site to compare with some the code of a toy ray tracer in Python.

Image Convolution

A tutorial on image convolution is available on a page at Arizona State University.
