A SYSTEM AND A METHOD FOR DETERMINING APPROXIMATE SET OF VISIBLE OBJECTS IN BEAM TRACING

摘要

A computer-implemented method for beam tracing, wherein a set of beams is a representation of a physical wave phenomenon, the method comprising: receiving information regarding a beam and potentially intersecting objects; executing beam-triangle intersection tests; discarding elements, for which an intersection test is negative; dividing the beam into smaller partial beams; providing data for parallel processing; discarding of triangles with respect to partial beams; dividing the partial beams into smaller partial beams; approximating the smaller partial beams with rays; for each ray finding the closest triangle if such a triangle exists; creating delimited smaller partial beams; selectively applying merging of smaller partial beams previously delimited.
