************************ Lighting Documentation v1.00 ************************ * Lighting with the programmable graphics pipeline currently requires the use of * the effects framework and works on the object level. This means the algorithm * with which you wish to illuminate your object will work on the entire object, not * a subset of that object. The inputs for the algorithm also work on the object level, * meaning all subsets will use the same values. * * To avoid bloating the object class, three variables will be used across the various * algorithms in different ways. It is very important to note that an algorithm may not * neccesarily use all three variables in its calculations. Also, each algorithm may * accept different ranges of values from each of the variables it does use. The * lighting algorithms available for use in the framework are described below: * * Functions * --------- * power(), setPower(float) * getRoughness(), setRoughness(float) * getIndexOfRefraction, setIndexOfRefraction(float) * getAlgorithm(), setAlgorithm(LightAlgorithm) * * Inputs for setAlgorithm() * PHONG * BLINN_PHONG * COOK_TORRANCE * OREN_NAYAR * WARD_ANISO * ASH_SHIRLEY * * == Phong == * Isotropic * * Input Effective Range * power 0.0 - 1000 * * Makes objects look plastic * ========================================================================== * == Blinn-Phong == * Isotropic * * Input Effective Range * power 0.0 - 1000 * * Like Phong, but uses less instructions, also gives objects a plastic look * ========================================================================== * == Cook-Torrance == * Isotropic * * Input Effective Range * roughness 0.0 - 15.0 * index of refraction 0.0 - 10.0 * * Gives objects a metallic look * ========================================================================== * == Oren-Nayar == * Isotropic * * Input Effective Range * roughness 0.0 - 2.0 * * Diffuse only model, good for making objects look rough * ========================================================================== * == Ward Anisotropic == * Anisotropic * * Input Effective Range * roughness 0.0 - 2.0 * power 0.0 - 2.0 * * Allows the manipulation of specular lobe (change its shape) * ========================================================================== * == Ashikhmin-Shirley == * Anisotropic * * Input Effective Range * roughness 0 - 10000 * power 0 - 10000 * index of refraction 0.0 - 10.0 * * Good for making objects look metal or plastic, and can manipulate specular lobe * ========================================================================== * * For more information on lighting, check out: http://wiki.gamedev.net/index.php/D3DBook:Lighting
