Abstract

Maximum projection is a volume rendering technique that, for each pixel, finds the maximum intensity along a projector. For certain important classes of data, this is an approximation to summation rendering which produces superior visualizations. In this paper we will show how maximum projection rendering with additional depth cues can be implemented using simple a#ne transformations in object space. This technique can be used together with 3D graphics libraries and standard graphics hardware,thus allowing interactive manipulations of the volume data. The algorithm presented in this paper allows for a wide range of tradeo#s between interactivity and image quality. 1 Introduction The existing approaches to volume visualization can be classified into two categories: direct volume rendering and model based techniques. While these two techniques have often been portrayed as competitors, we think they should actually be seen as being complementary. The method described in this paper use...
