ThreeDimSim: Environment mapping

This example shows a how a highly reflective surface can be generated using a technique called environment mapping. In this case an Environment Texture (EnvTexture) is applied on the surface of the loaded mesh (the head). The scene, without the object with the environment texture, is projected on the environment texture, and then the entire scene is rendered as usual, including the use of the generated texture. The result mimics a reflective surface without the need to use ray-tracing techniques.
