Matrix math for curved prims - N. W. Perry - 2022-12-01
Is it possible to get a rotation matrix for a circular primitive, given a simple (I guess quadratic) Bézier curve? All of our curved prims are circles or conical, and I’ve read that any affine transformation of a conic section will result in another conic section. If the simple Bézier curves are likewise conic (which may be a wrong assumption), then theoretically they can all be represented by a 2D shear matrix, right? |
