Multitexture Soft Reflections, Environment Mapped Bump Mapping and Cubic Environment Mapping on Radeon®

Figure 1 - Gloss mapped EMBM soft reflection and cubic environment mapping

The sample RadeonEMBMEnvCubeSoftReflect applies an environment mapped bump map (EMBM) to the reflecting wooden surface in the sample RadeonSoftReflect . The EMBM perturbs the texel look-up index into the projected soft refelction texture to give the surface a rough appearance. Additionally, it maps a dynamically generated cube map onto the teapot using the Radeon®'s cubic environment mapping. Figure 1 shows a screen shot of this sample.

RadeonEMBMEnvCubeSoftReflect Controls S - Toggle between regular and larger shear displacement M - Toggle between default (6) and more (12) samples J - Enable/Disable random jitter added to the shear displacement G - Toggle gloss mapping on/off [SPACE] - Advance Frame-by-frame [ENTER] - stop advancing Frame-by-frame [LEFT] - Rotate camera left [RIGHT] - Rotate camera right [ESC] - Quit
