Calculation of Tight Bounding Volumes for Cyclic CSG- Graphs*
Cyclic CSG graphs are a memory safe representation of objects with a very complex, recursive structure. This class of objects are defined by CSG-PL-Systems, an adaption of the well known Parametric Lindenmayer Systems (PL-Systems) to the CSG concept. They are a powerful tool to model natural phenomena like plants, clouds or fractal terrain but also linear fractals or any objects with a repetiti...
متن کاملInteractive Rendering of CSG Models
We describe a CSG rendering algorithm that requires no evaluation of the CSG tree beyond normal-ization and pruning. It renders directly from the normalized CSG tree and primitives described (to the graphics system) by their facetted boundaries. It behaves correctly in the presence of user dened, \near" and \far" clipping planes. It has been implemented on standard graphics workstations using I...
متن کاملRendering CSG scenes with general antialiasing
Ray-tracing is one of the most popular techniques for rendering 3D images. Effects such as shadows, reflection, refraction and so on can be produced with this technique. However, raytracing is a point-sampling technique with well-known aliasing problems. In particular, small objects and small shadows can be hidden between rays and not be detected. No ray-tracing method, even using oversampling,...
متن کاملModeling and Rendering of Various Natural Phenomena Consisting of Particles
The simulation of various natural phenomena is one of the important research fields in computer graphics. In particular, aspects such as sky, clouds, water, fire, trees, smoke, terrains, desert scenes, snow and fog are indispensable for creating realistic images of natural scenes, flight simulators and so on. Therefore, a lot of researchers have been trying to develop methods for simulating and...
متن کاملScalable GPU rendering of CSG models
Existing methods that are able to interactively render complex CSG objects with the aid of GPUs are both image based and severely bandwidth limited. In this paper we present a new approach to this problem whose main advantage is its capability to efficiently scale the dependency on CPU instruction throughput, memory bandwidth and GPU instruction throughput. Here, we render CSG objects composed ...
