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.
基于CATIA CAD的照明仿真新观看模式的阐述
在将照明模拟系统集成到CATIA CAD中,通常需要额外的视图模式,这些模式最初在CAD中是不存在的。本文描述了使用CATIA的本机CAA RADE编程环境直接在CATIA工作空间窗口中添加这样的视图模式。添加这些新的视图模式可以大大简化用户准备照明模拟数据。这里提到了以下额外的视图模式:几何镶嵌到三角形网格(在线框模式下),热图显示在场景上的光学值分布,以及球形全景预览。本文描述了在实时重绘附加数据时可能出现的问题,并提出了解决或绕过这些问题的可能方法。使用新的显示模式提供了调整一些场景参数和立即查看初步结果的可能性,而渲染这些场景可能需要几个小时。这样的附加功能可以显著地增加建模过程。
