Syntax

void rcRasterizeTriangles
(
    rcContext * ctx,
    const float * verts,
    const unsigned char * areas,
    const int nt,
    rcHeightfield & solid,
    const int flagMergeThr,
    const int rasterizationFlags,
    const int * rasterizationMasks
)

Remarks

Rasterizes triangles 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 triangle vertices. [(ax, ay, az, bx, by, bz, cx, by, cx) * 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 //UE4
rtzMasks	Mask for the rasterization flags [Size: hf.w*hf.h] //UE4
