摘要
虚拟手术系统研究是计算机图形学的一个重要领域,为了提高肌肉纤维纹理合成的真实感与实时性,文章采用了基于场向参数化的方法,并结合最光滑方向场进行了三维模型上的肌肉纤维纹理映射与合成,通过布置奇异点,模拟肌肉纤维损伤的状态。该系统实现了场向参数化的可视化及肌肉纤维纹理合成的简单交互,实验结果表明,系统的实时性与真实感均得到提高。
The research of virtual surgery system is an important research filed of computer graphics. In time of muscle filler texture synthesis, this paper adopted a metliod which based on field-aligned parameterization, combined witli the smootliestdirection field, the algorithm achieved the muscle fiber texture mapping and synthesis on the 3D models. It can mimic the state of muscle fiberinjury by arranging singular points. This system implements the visualization of field-aligned parameterization and simple interaction of musclefiber texture synthesis. The results show that the performance and realism of the system has been great improved.
