Get neighbor tile across a edge.
-
Parameters:
-
| patchid |
is the id of this patch |
| edge |
is the edge shared with the neigbor |
| position |
is the position over the edge in CCW across the patch. So if edge == 0, position is oriented like OT So if edge == 1, position is oriented like OS So if edge == 2, position is oriented like -OT So if edge == 3, position is oriented like -OS |
| patchOut |
will be filled with the output patch id |
| sOut |
will be filled with the output patch s coordinate |
| tOut |
will be filled with the output patch t coordinate |
| patchInfos |
is the vector of all patch info |
-
Returns:
-
false if no neighbor has been found or tile ratio is not the same than in this patch.

Adjusts a CPatchInfo array to get a symmetrized / rotated zone with matching oriented tiles.
This method only adjuste tile and vertex color array, does'nt transform vertices.
Transform an array of patchInfo by a symmetry on OY axis followed by a 90° CCW rotation (0, 1, 2, 3).
The method doesn't transform vertices. If symmetry, the method invert 0-3 and 1-2 vertices indexes to get CCW oriented patches. It will fix bind informations. The method fixes tile and color vertex arrays. The method fixes tile rotation, 256 cases and tile transistions.
Return false if something wrong.

uint8 NL3D::CPatchInfo::_CornerSmoothFlag [private]
|
|
| uint16 NL3D::CPatchInfo::BaseVertices[4]
|
|
|
|
The base corner vertices indices in the current zone. Used for patch connectivity.
Definition at line 125 of file src/3d/zone.h. |
| float NL3D::CPatchInfo::ErrorSize
|
|
|
|
The Base Size*bumpiness of the patch (/2 at each subdivide). Set to 0, if you want CZone to compute it for you.

"The don't smooth" flags.
For each edge of the patch (0~3), the flag means that this patch mustn't be smoothed with its neightbor. The n-th edge links the vertices "n" and "(n+1)%4". The flag for the n-th edge is (1<<n).

The Tile lumels for this patch.
There must be (OrderS*4+1)*(OrderT*4+1) tile lumels. Those are lumel value in tiles. There is 4x4 lumels by tiles plus last lumels. They are stored in line first order, from S=0 to 1, and T=0 to 1.

| uint8 NL3D::CPatchInfo::NoiseRotation

|
|
The orientation of the NoiseMap. 0,1,2,3. This represent a CCW rotation of the NoiseMap.

| std::vector<CTileColor> NL3D::CPatchInfo::TileColors
|
|
|
|
The Tile colors for this patch.
There must be (OrderS+1)*(OrderT+1) tile colors. Those are the colors at the corners of the tiles. They are stored in line first order, from S=0 to 1, and T=0 to 1.

There is (OrderS/2+1) * (OrderT/2+1) tiles light influence.
It indicates which static pointLight influence each corner of a TessBlock (block of 2*2 tiles).
If size==0, suppose no light influence. but CZone::retrieve() always return a size == (OrderS/2+1) * (OrderT/2+1).
They are stored in line first order, from S=0 to 1, and T=0 to 1.
