Two methods for wavelet-based volume rendering
(1996)Comp. Sc. Dept. internal reportThis paper describes two methods for wavelet domain rendering of volume data sets, which base on entire different paradigms for the approximation of the underlying volume rendering equation. The first approach comprises a ray-tracing algorithm for cardinal B-spline wavelet representations of both color and opacity values and carries out high quality images. We especially propose elaborated integration and evaluation schemes, where the ...Report -
Ray–tracing of multiresolution B–Spline volumes
(1995)Comp. Sc. Dept. internal reportThis paper describes a wavelet–based ray–tracing algorithm that carries out high quality images. Our appoach takes advantage of the multiresolution representation of the volume data and the self–similarity of the basis functions. The results are flexible high order approximations of the low albedo rendering equation. We propose accurate integration and evaluation schemes for shading and intensity computation. This paper also describes the ...Report
