Parameters

[in]	x	X Coordinate.
[in]	y	Y Coordinate.
[out]	out	Mesh/Triangle identifier and the barycentric weights of the pixel center.

Note

Enlighten converts all incoming meshes to CCW winding order; this means that the Barycentric coordinates created here may require reinterpretation when applied back to the source mesh. Unity and Unreal are examples of engines that would require flipping the order of weights, as they store meshes in CW winding order.
