Interactive 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 کاملHow to Create and Animate a Dancing Dinosaur with Implicit Surfaces
In this short paper we present a case study of creating a character using implicit surfaces and developing an animation sequence which brings it to life. We show some problems specific to implicit surfaces and discuss solutions we used to deal with them. Basic knowledge of animation techniques and implicit surfaces terminology is assumed.
متن کاملCurvature formulas for implicit curves and surfaces
Curvature formulas for implicit curves and surfaces are derived from the classical curvature formulas in Differential Geometry for parametric curves and surfaces. These closed formulas include curvature for implicit planar curves, curvature and torsion for implicit space curves, and mean and Gaussian curvature for implicit surfaces. Some extensions of these curvature formulas to higher dimensio...
متن کاملControlled Blending of Procedural Implicit Surfaces
Implicit surfaces are becoming increasingly popular in geometric modeling. Procedurally defined implicit surfaces, in particular surfaces built around skeletons, provide an intuitive representation for many natural objects, and objects commonly used in geometric modeling. This paper presents several techniques that provide good control over the way different skeletally defined implicit surfaces...
