The barycentric transformation

WebJan 17, 2015 · For triangles you can use mathutils.geometry.barycentric_transform: import mathutils.geometry pd = mathutils.geometry.barycentric_transform (p, v1, v2, v3, d1, d2, d3) To test if the point is inside a triangle you can use mathutils.geometry.intersect_point_tri. This is a neat solution! And I have one more question. WebJan 1, 2010 · A squared area is chosen and is decomposed using 3-level discrete biorthogonal wavelet transform.
