Product design : NURBS & trim curves #461

Closed nyue closed 3 years ago

nyue commented 3 years ago

Hi,

I understand from a recent webinar that OSPray is used in product design and car companies (e.g. Bentley) are using it.

Will NURBS surface and trim curves be supported geometry in the future for OSPray ?

Cheers

Well, I don't think so, at least not in the near future. Best way is to tessellate NURBS into triangles (or bilinear patches). It is not clear that direct ray intersection of NURBS provides benefits over a pre-tessellated representation.
