An analytical method to determine the visible parts of parametrically defined tensor-product surfaces is described. All vistbility calculations are strictly oriented on the (u, u)-parameter plane. This leads to substantial advantages over visibility algorithms based on the approximation of curved surfaces by sets of planar polygons. The new algorithm allows(More)

12 should be further investigated. Alternatively, robust and reasonably fast methods to solve t h e t wo s i m ultaneous nonlinear equations 1 and 2, should be explored, yielding a possible solution for the accessibility problem for both the elliptic and the hyperbolic surface regions.
