Real Time Implicit Bulging and Volume Preservation
Niall Linden, Hugh W. Reynolds, Carol O. Sullivan · 1999
Implicit Surfaces are particularly suitable for the animation of deformable objects, although some problems still remain, especially in real time applications. One problem is that of volume loss when objects are squashed. This paper presents a real time solution for the preservation of volume using dynamic creation of primitives in two dimensions. We also look at the unwanted blending problem and propose a more efficient solution. Keywords: Implicit Surfaces, Volume Preservation, Unwanted Blending, Real Time Animation. 1 Introduction As time has passed, and the power of computers has increased dramatically, problems that could only be solved off line are now becoming real time issues. One such problem is that of animating deformable objects. These are objects whose topology can change over time and which can join and separate. The use of Implicit Surfaces provides an elegant solution to these problems. The idea of Implicit Surfaces has been around for over 15 years and was init...
