Abstract
Recent years have shown a tremendous development in graphics processing unit(GPU) hardware. From initially being designed for discrete graphics, they arenow used in a wide area of applications, showing speed-ups of 10--50 times overtraditional CPUs. This talk discusses the use of GPUs to speed up approximativeimplicitization. Approximative implicitization is a computationally demandingalgorithm that finds the best, in a least squares sense, implicitrepresentation of a curve in 2D or surface in 3D.
