Abstract
During integration of lighting simulation systems into CATIA CAD often are needed additional view modes initially absent in this CAD. This article describes adding such view modes directly in CATIA workspace window using CATIA’s native CAA RADE programming environment. Adding these new view modes can significantly simplify user’s preparation of data for lighting simulation. Here the following additional view modes are mentioned: geometry tessellation to triangular meshes (in the wireframe mode), heat map dis-play of the optical values distribution over the scene, and spherical panorama preview. In the paper the problems which may occur while trying to redraw the additional data in real time are described and possible ways of solving or by-passing them are proposed. Using the new display modes provides a possibility of tuning some scene parameters and viewing preliminary results immediately while rendering of such scenes may take several hours. Such additional functionality can significantly increase the modeling process.
Highlights
Optical simulation systems allow synthesizing photorealistic images of various virtual 3D scenes as well as obtaining numerical values of various optical parameters of virtual objects, with sufficient speed and accuracy [1]
The most simple and convenient way to get such data for end user is integration of optical simulation systems with existing computer-aided design systems [2]. Such integration allows usage of ready object models which were designed at the earlier stages in the corresponding CAD systems
2 E.Birukov, A.Voloboy, E.Denisov important for CATIA users [2], so integration with this CAD is very important for the optical simulation
Summary
Optical simulation systems allow synthesizing photorealistic images of various virtual 3D scenes as well as obtaining numerical values of various optical parameters of virtual objects, with sufficient speed and accuracy [1]. The most simple and convenient way to get such data for end user is integration of optical simulation systems with existing computer-aided design systems [2]. Such integration allows usage of ready object models which were designed at the earlier stages in the corresponding CAD systems. The CATIA CAD system provides different modes and additional possibilities for displaying scene objects in its workspace. Among the view modes absent in the CATIA CAD system but important for optical simulation tasks there are most often required displaying of tessellation of geometrical objects into triangular meshes with different subdivision accuracy, and showing optical values at the surfaces of the geometrical objects in the form of a heat map. In this article is described a functionality of showing spherical panorama used as a background image directly in the CATIA workspace viewport
