shown in figure 3. The beam tree is computed in object space and then passed to a polygon renderer for scan conversion to form the final shaded image. 2.1. Object Space Beam Tracing The beam tree could be formed using any of several object space hidden surface algorithms. The …

The major disadvantage of ray tracing results from its point-sampling approach. ... For each beam-polygon intersection the beam is fragmented and new beams created for the reflected and transmitted swaths of light. These sub-beams are redirected with a 4×4 matrix transformation and recursively traced. This beam tree is an object space ...

These sub-beams are redirected with a 4×4 matrix transformation and recursively traced. This beam tree is an object space representation of the entire picture. Since the priority of polygons is pre-determined, the final picture with reflections, refractions, shadows, and hidden surface removal is easily drawn.

http://www.eng.utah.edu/~cs6958/papers/CG98.pdf
For each traversed voxel, we position its associated objects relatively to the beam. To determine that an object is outside a beam, we use the following rule: if there is a plane that separates the space in a half-space that contains completely the beam and a half-space that contains completely the object, then the object is outside the beam.

In this paper,we describe a beam tracing method that computes high-orderspecular reflection and transmission paths from fixed sources in large polygonal models fast enough to be used for au-ralization in interactive virtual environment systems. The key idea behind our method is to precompute and store spatial data struc-
