Modeling and Rendering of Bronze Articles

A system for modeling and rendering of the bronze articles is instroduced. First, we import the three dimensional mesh model and segment the model into regions by use of geometric features. Next, we parameterize these regions by modifying existing parameterization method to ensure the patterns mapped without distortion. Finally, the relief surface and the corrosion effects on the bronze articles are simulated through normal mapping, multiple texture blending and dilation techniques. We accelerate rendering by taking advantage of the parallelism and programmability of GPU. Through UI users are able to alter the arrangements of the patterns and corrosion effects with ease. Potential applications of our system are digital museum, digital library, design of decorative products with bronze features, and art education.
