Abstract

Recent interest in photo-realistic 3D modeling has appeared in a variety of areas. These models are extremely useful in a realistic simulation environment. When viewing these large models, however, the frame-rate of even the fastest computers can be extremely low. Therefore, methods to lower the resolution of the model, and thus increase the frame- rate, while retaining the realism are desired. By using a multi-resolution model, low-resolution representations can be used while interacting with or moving the model, and the details from the higher resolution representation added when the model is stationary. To aid in the creation of such a model, we have developed a new triangle mesh reduction technique based on pattern vectors which creates a representation of a model. The reduction method presented here is based on the edge collapse/vertex split concept since this method lends itself easily to the multi- resolution mesh concept. The uniqueness of this reduction method, however, comes in the form of the data representation. We not only use the position of the vertices, but also other geometric properties such as normal and curvature. In addition, we have the advantage of having even more information about the mesh than just structural information.
