Effective removal of detail for a multi-resolution viewer
Kari Pulli, Tony DeRose · 1996
Several authors have described how to construct a multiresolution surface model by adding wavelet coefficients to a base model in arbitrary order. We present a method that allows one to remove detail from a wavelet description, which is important for interactive viewing of multiresolution models. Introduction. Wavelet analysis has been shown to be an effective method for automatically generating accurate models of geometric models at different levels of resolution [4]. An especially attractive feature of wavelet-based models is that the most accurate version of the model already contains all the coarser approximations, so memory is not wasted when storing several models of the same object at different resolutions. An interactive viewer of multiresolution models may be used to render different amounts of detail depending on factors such as the the resolution of the output and the speed of the graphics engine. Should the user zoom in to an object, more detail can be added, but if the...
