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.
