TexturedRepTileBacklightRequirementsModels: NoneProperties: NoneEditions: TracePro ExpertIntroductionThere are a number of optical systems that use small, repeated optical geometry to perform. Examples include the structure for backlights, brightness enhancement films, and lenslet arrays. RepTile within TracePro allows repetitive structure to be placed on planar surfaces in a number of different patterns without the need to develop each one of the geometry elements. This not only saves time during the development phase, but also time during the ray trace analysis since the computation of intercepts with the RepTile geometry is computed analytically rather than through intersections with geometry. RepTile till now (i.e., prior to Version 4.0 of TracePro) has three cases:IntroductionThere是一个使用小型的光学系统，光学几何重复执行。例子包括背光，增亮膜，透镜阵列结构。爬行动物在TracePro中允许重复结构被放置在平面上许多不同的模式，而不需要开发每一个几何元素。这不仅在开发阶段节省时间，而且还通过与几何的交叉分析计算，而不是因为计算的与爬虫几何的拦截时间在射线跟踪分析。到现在爬行动物（即之前的TracePro4.0版）有三种情况：* Constant: the RepTile geometry (e.g., sphere radius) is constant over the Tiles (or cells) that extend across the RepTile boundary,* Variable Rows: the RepTile geometry (e.g., sphere radius) can vary as a function of the row number over the Tiles (or cells) that extend across the RepTile boundary, and* Parameterized: the RepTile geometry (e.g., sphere radius) can vary as a function of both the row and column numbers over the * Tiles (or cells) that extend across the RepTile boundary.常数是恒定的爬行动物的几何形状（如球体的半径）以上的瓷砖（或细胞），整个爬行动物的边界延伸，*变行：爬行动物的几何形状（如球体的半径）可以作为一个行号的瓷砖（或细胞）的功能变化扩展到整个爬行动物的界线，*参数：在双方的行和列数的函数可以改变的爬行动物的几何形状（如球体的半径）*爬虫边界延伸跨越的瓷砖（或细胞）。All three of these make a single piece of geometry (e.g., a sphere) within a Tile (or cell) that has both a width and height assigned to it. The cases allow more control of the variation of the geometry as one goes down the bulleted list. However, in all cases the RepTile geometry, in a sense, is deterministic, meaning there is no ability to have a random array of RepT
