-Terminology: Stencil Shadow Volume (sometimes called Stencil Shadows)
-An extrusion of the lit faces, beginning at the original geometry and ending
-further from the light source than the original geometry (presumably at least
-as far as the light's radius, if the light has a radius at all), capped at
-both front and back to avoid any problems (extrusion from dark faces also
-works but has a different set of problems)
-
-This is normally rendered using Carmack's Reverse technique, in which
-backfaces behind zbuffer (zfail) increment the stencil, and frontfaces behind
-zbuffer (zfail) decrement the stencil, the result is a stencil value of zero
-where shadows did not intersect the visible geometry, suitable as a stencil
-mask for rendering lighting everywhere but shadow.
-
-In our case to hopefully avoid the Creative Labs patent, we draw the backfaces
-as decrement and the frontfaces as increment, and we redefine the DepthFunc to
-GL_LESS (the patent uses GL_GEQUAL) which causes zfail when behind surfaces
-and zpass when infront (the patent draws where zpass with a GL_GEQUAL test),
-additionally we clear stencil to 128 to avoid the need for the unclamped
-incr/decr extension (not related to patent).
-
-Patent warning:
-This algorithm may be covered by Creative's patent (US Patent #6384822),
-however that patent is quite specific about increment on backfaces and
-decrement on frontfaces where zpass with GL_GEQUAL depth test, which is
-opposite this implementation and partially opposite Carmack's Reverse paper
-(which uses GL_LESS, but increments on backfaces and decrements on frontfaces).
-
-
-
-Terminology: Stencil Light Volume (sometimes called Light Volumes)
-Similar to a Stencil Shadow Volume, but inverted; rather than containing the
-areas in shadow it contains the areas in light, this can only be built
-quickly for certain limited cases (such as portal visibility from a point),
-but is quite useful for some effects (sunlight coming from sky polygons is
-one possible example, translucent occluders is another example).
-
-
-
-Terminology: Optimized Stencil Shadow Volume
-A Stencil Shadow Volume that has been processed sufficiently to ensure it has
-no duplicate coverage of areas (no need to shadow an area twice), often this
-greatly improves performance but is an operation too costly to use on moving
-lights (however completely optimal Stencil Light Volumes can be constructed
-in some ideal cases).
-
-
-
-Terminology: Per Pixel Lighting (sometimes abbreviated PPL)
-Per pixel evaluation of lighting equations, at a bare minimum this involves
-DOT3 shading of diffuse lighting (per pixel dotproduct of negated incidence
-vector and surface normal, using a texture of the surface bumps, called a
-NormalMap) if supported by hardware; in our case there is support for cards
-which are incapable of DOT3, the quality is quite poor however. Additionally
-it is desirable to have specular evaluation per pixel, per vertex
-normalization of specular halfangle vectors causes noticable distortion but
-is unavoidable on hardware without GL_ARB_fragment_program or
-GL_ARB_fragment_shader.
-
-
-
-Terminology: Normalization CubeMap
-A cubemap containing normalized dot3-encoded (vectors of length 1 or less
-encoded as RGB colors) for any possible direction, this technique allows per
-pixel calculation of incidence vector for per pixel lighting purposes, which
-would not otherwise be possible per pixel without GL_ARB_fragment_program or
-GL_ARB_fragment_shader.
-
-
-
-Terminology: 2D+1D Attenuation Texturing
-A very crude approximation of light attenuation with distance which results
-in cylindrical light shapes which fade vertically as a streak (some games
-such as Doom3 allow this to be rotated to be less noticable in specific
-cases), the technique is simply modulating lighting by two 2D textures (which
-can be the same) on different axes of projection (XY and Z, typically), this
-is the second best technique available without 3D Attenuation Texturing,
-GL_ARB_fragment_program or GL_ARB_fragment_shader technology.
-
-
-
-Terminology: 2D+1D Inverse Attenuation Texturing
-A clever method described in papers on the Abducted engine, this has a squared
-distance texture (bright on the outside, black in the middle), which is used
-twice using GL_ADD blending, the result of this is used in an inverse modulate
-(GL_ONE_MINUS_DST_ALPHA, GL_ZERO) to implement the equation
-lighting*=(1-((X*X+Y*Y)+(Z*Z))) which is spherical (unlike 2D+1D attenuation
-texturing).
-
-
-
-Terminology: 3D Attenuation Texturing
-A slightly crude approximation of light attenuation with distance, its flaws
-are limited radius and resolution (performance tradeoffs).
-
-
-
-Terminology: 3D Attenuation-Normalization Texturing
-A 3D Attenuation Texture merged with a Normalization CubeMap, by making the
-vectors shorter the lighting becomes darker, a very effective optimization of
-diffuse lighting if 3D Attenuation Textures are already used.
-
-
-
-Terminology: Light Cubemap Filtering
-A technique for modeling non-uniform light distribution according to
-direction, for example a lantern may use a cubemap to describe the light
-emission pattern of the cage around the lantern (as well as soot buildup
-discoloring the light in certain areas), often also used for softened grate
-shadows and light shining through a stained glass window (done crudely by
-texturing the lighting with a cubemap), another good example would be a disco
-light. This technique is used heavily in many games (Doom3 does not support
-this however).
-
-
-
-Terminology: Light Projection Filtering
-A technique for modeling shadowing of light passing through translucent
-surfaces, allowing stained glass windows and other effects to be done more
-elegantly than possible with Light Cubemap Filtering by applying an occluder
-texture to the lighting combined with a stencil light volume to limit the lit
-area, this technique is used by Doom3 for spotlights and flashlights, among
-other things, this can also be used more generally to render light passing
-through multiple translucent occluders in a scene (using a light volume to
-describe the area beyond the occluder, and thus mask off rendering of all
-other areas).
-
-
-
-Terminology: Doom3 Lighting
-A combination of Stencil Shadow Volume, Per Pixel Lighting, Normalization
-CubeMap, 2D+1D Attenuation Texturing, and Light Projection Filtering, as
-demonstrated by the game Doom3.
