基于包围盒的快速3D模型切割显示和标注算法

utaway illustrations of 3D models is a visualization technology used in illustrations of 3D scenes with complex inner structure, the technology try to cut part of outside objects in order to give a clear view of the inner objects. We mainly focus on cutaway technology of complex 3D scenes which have nesting occlusion relationships. By giving hierarchical and different types of cutaways, we provide a relative clear view of the inner objective objects and their context. We give a left-right irraditation labeling to the cutaway result, in order to provide semantics information. For better user experience, we propose one accelerating technoly using bounding-box of objects, through this accelerating, cutaway and labeling of relatively complex scenes can get nearly realtime framerates.
