Campbell Barton	fde4686d77	barycentric transform utility geometry function. ... 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.	2009-12-27 01:32:58 +00:00
Brecht Van Lommel	b83751d8c2	Math Lib: merging over some changes from the sculpt branch: ... * swap v2/v3 * multiply-and-add (madd) v3 * inline v3 short/float conversion * mul_v3_m3v3	2009-11-28 13:11:41 +00:00
Brecht Van Lommel	385875632d	Math Lib ... * Fix remaining issues before conversion. * Inline various vector functions, currently enabled for all platforms. I expect this to work in GCC/MSVC at least, if other platforms don't support it, #ifdef's can be added.	2009-11-10 19:13:05 +00:00
