River Pilot Simulator Benchmark

This is a simple benchmark that runs the River Pilot Simulator (RPS) for 30 seconds. The RPS is part of the RiverWeb project. It is the prototype exhibit that we installed at the Science Museum of Minnesota. More info here:

The scene is made up of some terrain covered with a large land-usage texture, tree billboards, a water plane showing a depth texture, a tugboat model, and river flow vectors. The terrain data was about 4 million triangles. It was decimated down to ~150,000 and broken up into 256 chunks for efficient culling. A typical scene has about 30,000 tris.

Scene statistics:
~30,000 tris
~6 MB of textures
700x700 resolution

Results

brighton:
benchmark: 266 frames 30.0302s 8.85774 fps
benchmark: 265 frames 30.0215s 8.82701 fps
benchmark: 264 frames 30.0769s 8.77751 fps

notes: MXE has only 4 MB texture. It is loading 16 MB of texture per second which is consistent with 6 MB (scene) - 4 MB (mem) = 2 MB per frame.

Eliminated texture loading. Used scaled-down textures and no tug textures:
benchmark: 412 frames 30.0287s 13.7202 fps
benchmark: 413 frames 30.022s 13.7566 fps

notes: trying to stay under the 4 MB limit for this project is hopeless. :-)
