CreateNURBS

[wahn]

Commit 79cd36d provides two .pbrt files containing NURBS patches. With order 3 and 4. They render fine with the C++ version:

For the Rust version we have to implement CreateNURBS (and some other helper functions):

std::vector<std::shared_ptr<Shape>> CreateNURBS(const Transform *o2w,
                                                const Transform *w2o,
                                                bool reverseOrientation,
                                                const ParamSet &params) {
...
}
