Representing and Rendering Surfaces with Points
نویسنده
چکیده
This report deals with the use of points as surface rendering and modeling primitives. The main components of point-based rendering and modeling algorithms are identified, different approaches are discussed and compared. The weaknesses of current point-based techniques are pointed out and for some of them a possible solution is suggested. A new algorithm for depth-of-field rendering based on surface splatting is presented. It features rendering time independent of the amount of depth-blur and depth-of-field rendering in scenes with semi-transparent surfaces. For this algorithm a mathematical analysis, an implementation and a discussion of results are given.

Haptic Rendering of Subdivision Surfaces
This report presents a new way of representing subdivision surfaces in a combined haptic and graphic environment. Subdivision surfaces is a technique for rendering smooth surfaces built up by arbitrary formed meshes and is primarily used in computer modeling and animation. Haptics can be described as rendering forces describing the outline of virtual objects aiming to enhance the realism by add...
متن کاملView Dependent Stochastic Sampling for Efficient Rendering of Point Sampled Surfaces
In this paper we present a new technique for rendering very large datasets representing point-sampled surfaces. Rendering efficiency is considerably improved by using stochastic sampling that is controlled using various object and view dependent image space properties. Most of the current rendering algorithms simplify the model in a preprocessing step before rendering. This simplification prima...
متن کاملInteractive Visualization of Non-Manifold Implicit Surfaces Using Pre-Integrated Volume Rendering
We present an interactive method of visualizing both manifold and non-manifold implicit surfaces. The implicit surfaces are directly visualized at interactive frame rates independent of surface complexity by the hardwareaccelerated volume rendering method. Although conventional implicit surfaces can represent only two-manifold surfaces, we have developed a technique of representing non-manifold...
متن کاملIRIS: Illustrative Rendering of Integral Surfaces
Integral surfaces are ideal tools to illustrate vector fields and fluid flow structures. However, these surfaces can be visually complex and exhibit difficult geometric properties, owing to strong stretching, shearing and folding of the flow from which they are derived. Many techniques for non-photorealistic rendering have been presented previously. It is, however, unclear how these techniques ...
