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