Syntax

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

    const int rasterizationFlags
)

Remarks

Rasterizes an indexed triangle mesh into the specified heightfield.

Spans will only be added for triangles that overlap the heightfield grid.

Parameters

Parameter	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]
int	Flags to change the rasterization behavior //UE4
