318 Common Part. Inputs and constants.
319
320 Inputs
321 --------
322 Standard:
323 v[0] == StartPos. Hence, It is the SplitPoint of the father face.
324 v[8] == Tex0 (xy)
325 v[9] == Tex1 (xy) (different meanings for Far and Tile).
326 v[13] == Tex2 (xy) (just for Tile mode).
327
328 Geomorph:
329 v[10] == { GeomFactor, MaxNearLimit }
330 * where GeomFactor == max(SizeFaceA, SizeFaceB) * OORefineThreshold.
331 It's means vertices are re-computed when the RefineThreshold setup change.
332
333 * MaxNearLimit= max(nearLimitFaceA, nearLimitFaceB)
334
335 v[11].xyz == EndPos-StartPos
336
337 Alpha: NB: Since only useful for Far1, v[12] is not in the VB for Far0 and Tile VertexBuffer.
338 v[12] == { TransitionSqrMin, OOTransitionSqrDelta}
339 * TransitionSqrMin, OOTransitionSqrDelta : Alpha transition, see preRender().
340 There is only 3 values possibles. It depends on Far1 type. Changed in preRender()
341
342
343 Constant:
344 --------
345 Setuped at beginning of CLandscape::render()
346 c[0..3]= ModelViewProjection Matrix.
347 c[4]= {0, 1, 0.5, 0}
348 c[5]= RefineCenter
349 c[6]= {TileDistFarSqr, OOTileDistDeltaSqr, *, *}
350 c[7]= ???
351 c[8..11]= ModelView Matrix (for Fog).
352 c[12]= PZBModelPosition: landscape center / delta Position to apply before multipliying by mviewMatrix
353
354
355 Fog Note:
356 -----------
357 Fog is computed on geomorphed position R1.
358 R1.w==1, and suppose that ModelViewMatrix has no Projection Part.
359 Then Homogenous-coordinate == Non-Homogenous-coordinate.
360 Hence we need only (FogVector*R1).z to get the FogC value.
361 => computed in just on instruction.

366 /*
367 Common start of the program for Far0, Far1 and Tile mode.
368 It compute the good Geomorphed position.
369 At the end of this program, nothing is written in the output register, and we have in the Temp Registers:
370
371 - R0= scratch
372 - R1= CurrentPos geomorphed
373 - R2.x= sqrDist= (startPos - RefineCenter).sqrnorm(). Useful for alpha computing.
374
375 Pgr Len= 18.
376 NB: 9 ope for normal errorMetric, and 9 ope for smoothing with TileNear.
377
378 The C code for this Program is: (v[] means data is a vertex input, c[] means it is a constant)
379 {
380 // Compute Basic ErrorMetric.
381 sqrDist= (v[StartPos] - c[RefineCenter]).sqrnorm()
382 ErrorMetric= v[GeomFactor] / sqrDist
383
384 // Compute ErrorMetric modified by TileNear transition.
385 f= (c[TileDistFarSqr] - sqrDist) * c[OOTileDistDeltaSqr]
386 clamp(f, 0, 1);
387 // ^4 gives better smooth result
388 f= sqr(f); f= sqr(f);
389 // interpolate the errorMetric
390 ErrorMetricModified= v[MaxNearLimit]*f + ErrorMetric*(1-f);
391
392 // Take the max errorMetric.
