Description

Performance template may be found here.

I am currently hard coding the scene into the executable front ends that invoke the renderer. I added several camera movement functions to my code so that I can interactively move the camera about the scene.

I implemented the extra image by downloading eight quads in sdts format and converted them to dem format with a another tool (google search sdts2dem.c). Next I stitched the dem files together with some of my own software and produced a floating point 2d nrrd. I decided I was interested in a zoomed out view, so I downsampled the data considerably.

Time spent: 4-5 days.
