The Curves primitive defined in RenderMan is useful for modelling and rendering ribbonlike objects. This paper gives a simple framework for ray-curve intersection tests in ray tracing, and provides concrete details for one form of the primitive. The form is especially important for fine objects such as hair and fur.

Ray tracing primitives. Mathematical preliminaries. Coordinate systems. To deal easily with the various primitive objects, you need to be able to work in all three of the standard 3D coordinate systems: rectangular (x,y,z), spherical polar ( ), and cylindrical polar ( ). To convert from one to another you use the following formulae.

Nakamaru & Ohno - Ray Tracing for Curves Primitive - A Bézier curve is approximated with a number of line segments obtained by recursively subdividing the curve - For each line segment: > Compute point P along the segment that is nearest the ray and determine if this distance is less than the thickness of the segment - To efficiently calculate ...
