Optimal Adaptive Polygonal Approximation of Parametric Surfaces
Luiz Velho e Luiz Henrique de Figueiredo

We present a new method for adaptive polygonization of parametric surfaces.
The method combines
recursive simplicial subdivision of the domain and
point sampling along curves on the surface.
We avoid cracks in the polygonal mesh by
determining the optimal sampling rate along the edges of a cell
before subdividing it.
The method is suitable for surfaces with low variations,
such as bicubic patches,
as well as for surfaces with high variations,
such as height fields
