Abstract: A method, apparatus, system, article of manufacture, and computer readable storage medium provide the ability to render point cloud data. After obtaining point cloud data, polygons are fit to the point cloud data. A texture atlas is created for each of the polygons. A lookup table is generated from the texture atlases and maps each pixel to a corresponding texture location. When a scene is loaded for rendering/processing, the polygons and texture atlas are loaded and projected into an off-screen buffer that defines a depth map of the scene with approximations of a depth per pixel in screen space. The off-screen buffer is used as a lookup table to determine texture data to be rendered for the scene.

Abstract translation: 方法，装置，系统，制品和计算机可读存储介质提供渲染点云数据的能力。 获得点云数据后，多边形适合点云数据。 为每个多边形创建纹理图集。 从纹理图集生成查找表，并将每个像素映射到相应的纹理位置。 当加载场景进行渲染/处理时，多边形和纹理图集被加载并投影到屏幕外缓冲区中，该屏幕缓冲区用屏幕空间中每像素的深度近似定义场景的深度图。 离屏缓冲器用作查找表以确定要为场景渲染的纹理数据。
