Point-based Level-of-detail with Object Textures

We introduce Object Textures, a technique for mapping complex objects onto small texture patches which are dynamically retrieved during rendering. Each patch contains a subset of the object’s primitives which are read from GPU texture by a geometry shader. As a proof of concept, we demonstrate the method with a Level-of-Detail application for Point-Based Rendering. Only the coarsest resolution level is sent to the GPU while the more refined levels are recovered from an Object Texture.
