Question: Accurate intersection for analytic curves

[Mo1999]

Hi,

A quick question:

Are there the intersection functions for the common analytic curves? like straightline/straightline, arc/straightline, arc/bspline, arc/arc and so on and on. It seems that we represent all curves using NURBS. If we treat all curves as NURBS to do intersection, will the result be accurate?

Thank you very much.

Thanks for checking out verb!

If you find a case where an intersection result is not correct, it is a
bug.

You can represent any conic exactly using a NURBS curve. Under the hood,
verb represents all Curve and Surface types as a NURBS - not just for
intersection. This is the elegance of this particular representation.

True, certain types might be represented more compactly using another
formulation (and this might be in store in the future for verb), but
presently that would make the core far more complex for minimal space and
speed improvements.

Thanks!
