Spatially encoded image-space simplifications for interactive walkthrough
Andrew Wilson, Dinesh Manocha · 2002
Many interesting geometric environments contain more primitives than standard rendering techniques can handle at interactive rates. Sample-based rendering acceleration methods such as the use of impostors for distant geometry can be considered simplification techniques in that they replace primitives with a representation that contains less information but is less expensive to render. In this dissertation we address two problems related to the construction, representation, and rendering of image-based simplifications. First, we present an incremental algorithm for generating such samples based on estimates of the visibility error within a region. We use the Voronoi diagram of existing sample locations to find
