METHOD AND DEVICE FOR ANALYZING OPTICAL ENVIRONMENT

摘要

PURPOSE:To reduce errors and to shorten a simulation time by synthesizing/ decomposing tracking meshes and reconstituting a reflecting light source mesh having an aspect ratio closer to '1' and a larger shape. CONSTITUTION:Many X-Y, Y-Z and Z-X planes decomposing all inner surfaces forming an optical environment space to be analyzed in each object are inputted as coordinates, the whole space is divided into tracking blocks 30 and respective surfaces of respective objects forming all the inner surfaces are thinnly divided by many planes to form tracking meshes 31 having optional shapes. Small/flat meshes out of the meshes 31 are synthesized/divided in each object to recompose a reflecting light source mesh 32 having an aspect ratio more close to '1' and a larger shape. Both the meshes 31, 32 are used as light sources, the meshes 31 are used as reflecting faces and the locus of light beams mutually reflected in a room space is tracked by using the blocks 30 to complete the quantity of received light of respective meshes 31.
