I am looking to represent some scientific data that changes in real-time by displaying the data as a 3d surface. I am thinking that one way to do this would be to build and render a heightmap. I am wondering if anyone has any simple pointers or tuts on how best to do this with OGL. I was thinking that as I get the real-time data updates I can update values of intensity in the heightmap and have that automatically drive the final rendering. Any suggestions on this?
