Image Description, by
Inspired by Jaap's GBA screenshots from his 3d engine, I thought I'd try some
raytracing on the GBA. For anyone that grew up with dos mode13 graphics programming,
programming the GBA is like taking a walk in the park, really nice.
I use the 15bit Mode3, rendering times are 2-3 mins for a simple picture, and 5 times
slower with supersampling on.
Features:
Plane and Sphere primitives
Phong shading
Shadows
Reflections
Supersampling
As you can see I use iGBA for emulation and I use ARM Software Development Toolkit v2.50 for
compilation. The source code the be found at my homepage http://come.to/polygone.
I have no idea if it works on the actual hardware, but if someone tries please tell me what
happened.
