Environment mapping

(Position 3)

TechTest Model using Reflection-Shading with a Environment-Texture

Environment map is used for metalic and glass objects. The effect is here used together with texture mapping, diffuse shading, and specular shading. Mapping coordinates are not generated by usual GL_SPHERE_MAP, but are rather custom calculated for full 360 degrees view independent environment mapping. The environment map is generated using all 6 environment views from the object position.
