Vegetable, without bend for now.
Inputs
--------
v[0] == Pos to Center of the vegetable in world space.
v[10] == Center of the vegetable in world space.
v[2] == Normal (present if lighted only)
v[3] == Color (if unlit) or DiffuseColor (if lighted)
v[4] == SecondaryColor (==ambient if Lighted, and use only Alpha part for DLM if Unlit)
v[8] == Tex0 (xy)
v[9] == BendInfo (xyz) = {BendWeight/2, BendPhase, BendFrequencyFactor}
NB: /2 because compute a quaternion
Changes: If unlit, then small changes:
v[0] == Pos to center, with v[0].w == BendWeight * v[0].norm()
v[9] == BendInfo/BlendInfo (xyzw) = {v[0].norm(), BendPhase, BendFrequencyFactor, BlendDist}
NB: v[9].w. is used only in Unlit+2Sided+AlphaBlend. But prefer do this for gestion purpose:
to have only one VBAllocator for all modes.
NB: Color and Secondary color Alpha Part contains Dynamic LightMap UV, (in 8 bits).
Constant:
--------
Setuped at beginning of CVegetableManager::render()
c[0..3]= ModelViewProjection Matrix.
c[6]= Fog vector.
c[8]= {0, 1, 0.5, 2}
c[9]= unit world space Directionnal light.
c[10]= camera pos in world space.
c[11]= {1/DistBlendTransition}
NB: DiffuseColor and AmbientColor of vertex must have been pre-multiplied by lightColor
// Bend:
c[16]= quaternion axis. w==1, and z must be 0
c[17]= { timeAnim , WindPower, WindPower*(1-WindBendMin)/2, 0 }
c[18]= High order Taylor cos coefficient: { -1/2, 1/24, -1/720, 1/40320 }
c[19]= Low order Taylor cos coefficient: { 1, -1/2, 1/24, -1/720 }
c[20]= Low order Taylor sin coefficient: { 1, -1/6, 1/120, -1/5040 }
c[21]= Special constant vector for quatToMatrix: { 0, 1, -1, 0 }
c[22]= {0.5, Pi, 2*Pi, 1/(2*Pi)}
c[23]= {64, 0, 0, 0} (size of the LUT)
// Bend Lut:
c[32..95] 64 Lut entries for cos-like animation
Fog Note:
-----------
Fog should be disabled, because not computed (for speed consideration and becasue micro-vegetation should never
be in Fog).
Speed Note:
-----------
Max program length (lighted/2Sided) is:
29 (bend-quaternion) +
16 (rotNormal + bend + lit 2Sided) +
5 (proj + tex)
2 (Dynamic lightmap copy)
51
Normal program length (unlit/2Sided/No Alpha Blend) is:
12 (bend-delta) +
1 (unlit) +
5 (proj + tex)
2 (Dynamic lightmap copy)
20
AlphaBlend program length (unlit/2Sided/Alpha Blend) is:
12 (bend-delta) +
1 (unlit) +
5 (Alpha Blend)
5 (proj + tex)
2 (Dynamic lightmap copy)
