Algorithm of Efficient Ray Tracing of Complex Scenes

ZHAO Shuang1,LI Xuejun2(1.Beijing Institute of Tracking and Telecommunications Technology,Beijing 100094;2.Computer Graphic Lab,Academy of Equipment Command & Technology,Beijing 101416)  
To improve the speed,accelerating algorithm for ray tracing is fully studied and compared and an improved 3d-DDA ray tracing algorithm based on auto-grouping is presented.It doesn’t divide the whole space,but auto-grouping the whole scenes,to divide the group that including enough num of entities.And to interact with ray combine with bounding volume,the entity link is saved by grid,the ray proceeding by the change of t.The accelerating algorithm not only improves the rendering speed more than ten times but also brings no depress on image quality.It gives a more capability method for the application of rendering 3-D graphics.
