A new method to approximate the volume rendering equation using wavelet bases and piecewise polynomials
(1994)ETH, Eidgenössische Technische Hochschule Zürich, Departement Informatik, Institut für InformationssystemeIn the following paper we describe a new generic method to find an approximate solution for the volume rendering equation using hierarchical, orthonormal wavelet basis functions. The approach is based on the idea that an initial volume data set can be decomposed into a pyramidal representation by means of a 3D wavelet transform. Once the wavelet function is described analytically, it is possible to approximate the volume density function. ...Report
