Haptic 3D mesh painting based on dynamic subdivision

Abstract

In this paper, we present a haptic painting system which provides users an easy way to accurately add color on the mesh models. Unlike some of previously published methods which require texture mapping or point resampling, our system is totally mesh-based. Since a local dynamic subdivision algorithm has been developed in our method, the quality of painting can be less dependent on the original mesh density so that fine details can also be created in sparse models. Sample studies have shown that the visual painting results on mesh models are good enough for early industrial design of multi-materials (or multi-colors) parts where frequent and easy changes of painting are required. Our approach can also provide useful information in mesh editing like smoothing and cutting, which makes the system possible to be further developed into a 3D interactive design tool for parts made of multi-materials that are normally manufactured by multi-shot molding processes. © 2008 CAD Solutions, LLC.
