I started testing the physics engine of the prototype today. Since we're dealing with a standardized triangle, I'm feeding the engine various ball positions and velocities to see if it detects a collision. The standardized triangle is located at ((0, 0, 0), (1, 0, 1), (1, 0, 0)). Among the values tested:

Testing surface collision:

• Ball=(.2, 5, .2), Velocity=(0, -10, 0), Radius=1, returned alpha=0.40202
• Ball=(.2, 10.9, .2), Velocity=(0, -10, 0), Radius=1, returned alpha=0.99202
• Ball=(2, 2, 2), Velocity=(-2, -2, -2), Radius=1, returned alpha=0.64646

Testing edge collision:

• Ball=(.5, 0, -1), Velocity=(0, 0, 10), Radius=1, returned alpha=0
• Ball=(.5, 0, -10), Velocity=(0, 0, 10), Radius=1, returned alpha=0.9

Testing vertex collision:

• Ball=(0, 1, 0), Velocity=(0, 1, 0), Radius=1, returned alpha=0
• Ball=(0, 1.999, 0), Velocity=(0, 1, 0), Radius=1, returned alpha=0.999

Testing non-collisions:

• Ball=(0, 2, 0), Velocity=(0, 1, 0), Radius=1, returned alpha=1
• Ball=(5, 5, 5), Velocity=(0, -10, 0), Radius=1, returned alpha=1
• Ball=(2, 2, 2), Velocity=(-1, -1, -1), Radius=1, returned alpha=1

Finalized the UML diagrams, WBS, Gnatt chart, etc.

Implemented a timer.

The prototype can now read triangle and ball coordinates and ball velocity from a file. I also created a handful of test files to use, including a cube.

I played around with the code to load files. You can now use RAW files generated by MilkShape?, combined with our own custom MG files, which specify ball coordinates, and, eventually, texture information.
