Abstract

Animation of a time-varying 3-D scalar field distribution requires generation of a set of images at a sampled time intervals i.e. frames. Although, volume rendering method can be very advantageous for such 3-D scalar field visualizations, in case of animation, the computation time needed for generation of the entire set of images can be considerably long. To address this problem, this paper proposes a fast volume rendering method which utilizes orthonormal wavelets. The coherency between frames, in the proposed method, is eliminated by expanding the scalar field into a series of wavelets. Application of the proposed method for time-varying eddy-current density distribution inside an aluminum plate (TEAM Workshop Problem 7) is given
