摘要:
This document describes systems and techniques for representing computer-generated objects with a limit mesh. In general, the systems and techniques may generate an object's form or appearance based on an estimation of how the object would look if shapes that form the object were infinitely subdivided to create a smooth surface for the object. For example, when a user views a distance object in a video game, its shape can be estimated by calculating an approximation of what the object would look like if the polygons that make up the object were infinitely divided. As the user approaches the object, curving solutions that may be embedded in the object can be used to construct curves for the object so that it appears smooth.
