Point-based Modelling and Rendering using Radial Basis FunctionsAbstract:A point-based 3D surface modelling technique combined with a new point rendering technique is presented. Surfaces are modelled by specifying a set of unorganized points on the surface. An implicit representation of the surface through these points minimizing the bending energy is then calculated using radial basis functions while guaranteeing a specifiable continuity. The surface is directly rendered view-dependently in an output-sensitive multiresolution manner without the creation of a polygonal mesh representation. This is done by the local generation of 3D surface points for the rendering adapted to the output device. A new texturing technique using the material properties of the points is presented.Keywords:Approximation of surfaces and contours, Spline and piecewise polynomial approximation, Picture/Image Generation, Display algorithms, Computational Geometry and Object Modeling, Curve, surface, solid, and object representations |
