Primitive Geometric Operations on Planar Algebraic Curves with Gaussian Approximation
We present a curve approximation method which approximates each planar algebraic curve segment by discrete curve points at each of which the curve has its gradient from a set of uniformly distributed normals. This method, called Gaussian Approximation (GAP), provides efficient algorithms for various primitive geometric operations, especially for those related with gradients such as common tange...

متن کاملSurjectivity of Gaussian Maps for Curves on Enriques Surfaces
Making suitable generalizations of known results we prove some general facts about Gaussian maps. The above are then used, in the second part of the article, to give a set of conditions that insure the surjectivity of Gaussian maps for curves on Enriques surfaces. To do this we also solve a problem of independent interest: a tetragonal curve of genus g ≥ 7 lying on an Enriques surface and gener...

متن کاملGaussian Approximations of Objects Bounded by Algebraic Curves
We present a discrete approximation method for planar algebraic curves. This discrete approximation is hierarchical, curvature dependent, and provides eecient algorithms for various primitive geometric operations on algebraic curves. We consider applications on the curve intersections , the distance computations, and the common tangent and convolution computations. We implemented these approxim...
