Virtual surgery system

This paper describes the development of a virtual surgery system, called VQSplat. The system takes volume data as inputs and is capable of display multiple volumetric models, manipulating and editing (cutting) them. The system uses a hierarchical multi-resolution point rendering system, which is derived from an existing point rendering system, QSplat. The features of VQSplat are listed as follows: Use hierarchical multi-resolution point rendering system to render volume data; Support multiple translucent object display; Support object selection, manipulation, free cutting; A unique hierarchical data structure to accelerate the rendering process, as well as cutting, and object splitting; integrated support of raw volume data importing, image enhancement, normal estimation; and portable code. Separate core library with user interface.
