Conversion of Global Illumination into VRM Textures
Abstract:
One aspect of export of illumination maps (i-maps) into VRML format is considered in the paper. The aspect concerns mapping of indirect illumination onto textured surfaces. The described algorithm correctly calculates physical values of illumination stored in i-maps for each pixel of resultant texture containing as initial usual texture as well as calculated illumination. The VRML files can be browsed in any available browser. Due to proposed method it is possible to reduce the number of triangles and the volume of texture memory. This leads to interactive speed of rendering of huge models preserving high quality of illuminance distribution.
