Cubics cannot translate perfectly into quadratics, no. You can estimate a set of quadratics to build what appears to be a cubic, but they're not identical at any arbitrary resolution.
Quadratic bezier curves, unlike cubic ones, do actually map really well onto GPUs (given their basis on triangles) quite unlike what you've said here.
- starmole 12y agoSorry for not being clear. Of course you are right, they are not the same. What I tried to say was that in the context of rendering approximating cubics by quadratics will not be the bottleneck.
