Abstract

Visual optimization of three dimensional models in computer automated design is disclosed herein. An example method includes receiving a three dimensional model having a first rendering complexity level, displaying the three dimensional model in such a way that areas of complexity are visually distinct from other areas, based on an optimization schema applied to the three dimensional model, applying the optimization schema to decimate the areas of complexity such that the three dimensional model can be rendered at a second rendering complexity level, the decimation being bounded by a visual quality level for the three dimensional model, and displaying the three dimensional model at the second rendering complexity level on a display system.
