HitTriangleVertexPositionsKHR
HitTriangleVertexPositionsKHR
A variable decorated with the HitTriangleVertexPositionsKHR decoration
will specify the object space vertices of the triangle at the current
intersection in application-provided order.
The positions returned are transformed by the geometry transform, which is
performed at standard floating-point
precision, but without a specifically defined order of floating-point
operations to perform the matrix multiplication.
