Abstract

The present disclosure is directed toward systems and methods for providing a preview that includes a visualization of various properties of an object to be printed from a three-dimensional input model. For example, systems and methods described herein involve performing one or more of a printability analysis, appearance analysis, true-visual analysis, accuracy analysis, and an integrity analysis to identify defects, visual characteristics and other properties of the object to be printed. Systems and methods described herein further relate to generating texture maps and applying the texture maps to three-dimensional renderings of the three-dimensional model to provide an interactive preview to enable a user to view and comprehend various issues associated with printing the object from the three-dimensional model.
