HARDWARE IMPLEMENTATION OF EWA For Point-Based Three-Dimensional Graphics Rendering
Adam Herout, Pavel Zemčík, Julien Reptin · Kluwer Academic Publishers eBooks · 2006
This paper presents a novel algorithm for rasterization of circular scene elements projected as ellipses, suitable for hardware acceleration of pointbased scene rendering. The algorithm is based on the screen space Elliptical Weighted Average (EWA) filter, promising high quality rendering, support for transparent objects, screen space and texture space antialiasing, etc.
