The "curves" primitive provides a way to define ribbon-like objects such as fur and hair. Ray tracing thin primitives is a difficult problem. It is possible to compute ray/curve intersections without tessellation [Nakamaru and Ohno 2002], but it requires many samples to reduce aliasing. On the other hand, GPU/rasterization based methods incorporate the(More)
