From 2 triangles and 1 point, the relative position between the point and the first triangle is applied to the second triangle to find the target point. the barycentric weights are calculated in 2D space with a signed area so values outside the triangle bounds are supported. wrapped by python: pt_to = Geometry.BarycentricTransform(pt_from, t1a, t1b, t1c, t2a, t1b, t1c) NOTE: - moved some barycentric weight functions out of projection painting into the math lib. - ended up making some of the math functions use const args. TODO: - support exceptional cases. zero area tries and similar.
