Y. Dobashi, T. Yamamoto, T. Nishita
Proceedings the Eighth Pacific Conference on Computer Graphics and Applications  
The purpose of this paper is to develop a method for displaying shafts of light at interactive rates by making use of the graphics hardware.  ...  The method makes use of hardware-accelerated volume rendering techniques to display the shafts of light.  ...  Appendix A As shown in Fig A. 1, a local coordinate system with its origin at a position of a light source is assumed. z-axis is assumed to coincide with the direction of the light source called an illumination  ...
