Lighting

Instructions to incorporate advanced lighting into your game:

Download the full working solution here:
OR
Download just the files that have changes relevant to lighting here:

Copy from the files or manually code the following:

Configuration.h
Increase the MAX_STR_ARRAYS macro by 1 (Line 46)
Add two more elements to the Integer enum: GF_NO_ALGS and GF_DF_ALGO (Lines 88, 89)
Add an element to the StrArray enum: GF_LITDESC (Line 127)
Create a macro called LIGHT_DESCRIPTIONS (Line 331)
Create an enum called LightAlgorithm (Line 389)

Context.cpp

************************ 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
* necessarily 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
* ==========================================================================
