both front and back to avoid any problems (extrusion from dark faces also
works but has a different set of problems)
-This is 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 we use a biased stencil clear of 128 to avoid requiring the
-stencil wrap extension (but probably should support it), and to address
-Creative's patent on this sort of technology we also draw the frontfaces
-first, and backfaces second (decrement, increment).
+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)
-on Carmack's Reverse paper (which I have not read), however that patent
-seems to be about drawing a stencil shadow from a model in an otherwise
-unshadowed scene, where as realtime lighting technology draws light where
-shadows do not lie.
+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: 2D Attenuation Texturing
+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

+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: Light Cubemap Filtering
A technique for modeling non-uniform light distribution according to
-direction, for example projecting a stained glass window image onto a wall,
-this is done by texturing the lighting with a cubemap.

+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).

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
