Preprint : Clip Art Rendering of Smooth Isosurfaces
Clip art is a simplified illustration form consisting of layered filled polygons or closed curves used to convey 3-D shape information in a 2-D vector graphics format. This paper focuses on the problem of direct conversion of smooth surfaces, ranging from the free-form shapes of art and design to the mathematical structures of geometry and topology, into a clip art form suitable for illustratio...

متن کاملIllustration of Smooth Isosurfaces
We present in this paper a new particle-based method for sampling and rendering several types of the nonphotorealistic feature contours on implicit surfaces: silhouette, shadow and suggestive contours. We introduce a curve adhesion behavior for dynamic particles that brings up the possibility to render any contour that is defined as an intersection of two smooth implicit surfaces. In the case o...
متن کاملHardware Accelerated Point Rendering of Isosurfaces
Interactive volume sculpting and volume editing often employ surface based visualization techniques, and interactive applications require fast generation and rendering of surface primitives. In this paper, we revisit point primitives as an alternative to triangle primitives. We propose an approximate technique for point scaling using distance attenuation which makes it possible to render points...
متن کاملInterval arithmetic algorithms for rendering isosurfaces
The use of interval arithmetic for ray tracing implicit surfaces is analyzed in terms of its reliability and performance. This paper analyzes when and how to use interval arithmetic as an alternative to the methods used in POV-Ray for ray intersection. Interval methods are applied as robust approaches for solving the ray-surface intersection problem; i.e. to find the minimal root in a set of an...
