Hello

I am new to POVRAY.
I was wondering if it has capabilities of ray tracing surfaces represented by
higher order meshes (cubic spllines instead of triangular mesh).

Best
Anton

It does do bezier patches. They're not represented as meshes though, just
individual patches.

In addition, it supports something called "parametrics", which can be considered
a generalization of spline patches, defined by an arbitrary set of functions
x(u,v), y(u,v) and z(u,v), with u,v ranging from 0,0 to 1,1. I bet they could
be used to do cubic spline patches, too. Again though, no support for complete
meshes.
