|
Inputs
|
||
|
|
--------
|
||
|
|
Standard:
|
||
|
|
v[0] == StartPos. Hence, It is the SplitPoint of the father face.
|
||
|
|
v[8] == Tex0 (xy)
|
||
|
|
v[9] == Tex1 (xy) (different meanings for Far and Tile).
|
||
|
|
v[13] == Tex2 (xy) (just for Tile mode).
|
||
|
|
|
||
|
|
Geomorph:
|
||
|
|
v[10] == { GeomFactor, MaxNearLimit }
|
||
|
|
* where GeomFactor == max(SizeFaceA, SizeFaceB) * OORefineThreshold.
|
||
|
|
It's means vertices are re-computed when the RefineThreshold setup change.
|
||
|
|
|
||
|
|
* MaxNearLimit= max(nearLimitFaceA, nearLimitFaceB)
|
||
|
|
|
||
|
|
v[11].xyz == EndPos-StartPos
|
||
|
|
|
||
|
|
Alpha: NB: Since only useful for Far1, v[12] is not in the VB for Far0 and Tile VertexBuffer.
|
||
|
|
v[12] == { TransitionSqrMin, OOTransitionSqrDelta}
|
||
|
|
* TransitionSqrMin, OOTransitionSqrDelta : Alpha transition, see preRender().
|
||
|
|
There is only 3 values possibles. It depends on Far1 type. Changed in preRender()
|
||
|
|
|
||
|
|
|
||
|
|
Constant:
|
||
|
|
--------
|
||
|
|
Setuped at beginning of CLandscape::render()
|
||
|
|
c[0..3]= ModelViewProjection Matrix.
|
||
|
|
c[4]= {0, 1, 0.5, 0}
|
||
|
|
c[5]= RefineCenter
|
||
|
|
c[6]= {TileDistFarSqr, OOTileDistDeltaSqr, *, *}
|
||
|
|
c[7]= ???
|
||
|
|
c[8..11]= ModelView Matrix (for Fog).
|
||
|
|
c[12]= PZBModelPosition: landscape center / delta Position to apply before multipliying by mviewMatrix
|
||
|
|
|
||
|
|
|
||
|
|
Fog Note:
|
||
|
|
-----------
|
||
|
|
Fog is computed on geomorphed position R1.
|
||
|
|
R1.w==1, and suppose that ModelViewMatrix has no Projection Part.
|
||
|
|
Then Homogenous-coordinate == Non-Homogenous-coordinate.
|
||
|
|
Hence we need only (FogVector*R1).z to get the FogC value.
|
||
|
|
=> computed in just on instruction.
