ROOT 6.10/09 Reference Guide |
A parametric surface is a surface defined by a parametric equation, involving two parameters (u, v):
For example, "limpet torus" surface can be defined as:
where -pi <= u <= pi, -pi <= v <= pi.
$ROOTSYS/tutorials/gl/glparametric.C
contains more examples.
Parametric equations can be specified:
