void rcRasterizeTriangles
(
rcContext * ctx,
const rcReal * verts,
const int nv,
const unsigned short * tris,
const unsigned char * areas,
const int nt,
rcHeightfield & solid,

Remarks
Rasterizes an indexed triangle mesh into the specified heightfield.
Spans will only be added for triangles that overlap the heightfield grid.
Parameters
| Name | Description |
|---|---|
| ctx | The build context to use during the operation. |
| verts | The vertices. [(x, y, z) * nv] |
| nv | The number of vertices. |
| tris | The triangle indices. [(vertA, vertB, vertC) * nt] |
| areas | The area id's of the triangles. [Limit: <= RC_WALKABLE_AREA] [Size: nt] |
| nt | The number of triangles. |
| solid | An initialized heightfield. |
| flagMergeThr | The distance where the walkable flag is favored over the non-walkable flag. [Limit: >= 0] [Units: vx] |
| rtzFlags | Flags to change the rasterization behavior //UE |
| rtzMasks | Mask for the rasterization flags [Size: hf.w*hf.h] //UE |
