Martin Peternell (Technische Universität Wien)
In the present talk it will be shown that polynomial quadratic triangular
Bezier surfaces are LN-surfaces which means that their normal vector field
n(u,v) can be parametrized by linear coordinate functions.
The close relation to quadratic Cremona transformations in the parameter
domain is elucidated. These reparameterizations
can be used for the computation of convolution surfaces.
