Syntax

void rcRasterizeTriangle
(
    rcContext * ctx,
    const float * v0,
    const float * v1,
    const float * v2,
    const unsigned char area,
    rcHeightfield & solid,

)

Remarks

Rasterizes a triangle into the specified heightfield.

No spans will be added if the triangle does not overlap the heightfield grid.

Parameters

Parameter	Description
ctx	The build context to use during the operation.
v0	Triangle vertex 0 [(x, y, z)]
v1	Triangle vertex 1 [(x, y, z)]
v2	Triangle vertex 2 [(x, y, z)]
area	The area id of the triangle. [Limit: <= #RC_WALKABLE_AREA]
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
