get3DFaceNormal

Returns a normal vector for a face in the underlying 3d mesh.

void get3DFaceNormal(int32_t faceIndex, float& resultX, float& resultY, float& resultZ) const;

	faceIndex		The index of the 3d face to return the normal for.
	resultX		Returns the X coordinate of the normal.
	resultY		Returns the Y coordinate of the normal.
	resultZ		Returns the Y coordinate of the normal.

Use iGround::get3DFaceAtPosition() to obtain a 3D face index.

The returned vector is unit length and points in a direction up from the ground.

void get3DFaceNormal(int faceIndex, out float resultX, out float resultY, out float resultZ);

void get3DFaceNormal(int faceIndex, float_OutArgument resultX, float_OutArgument resultY, float_OutArgument resultZ);
