| 摘 要： | 针对复杂产品模型较大、小型零部件多的特点,提出一种动态装配对象可见性计算方法.该算法将装配结构树表达为层次包围盒场景图,在实时绘制时结合视锥剔除和细节剔除,采用改进的快速查询策略实现虚拟装配对象的可见性判断和剔除.实验结果表明,该方法能高效地剔除动态装配对象中的细小像素个体,使虚拟装配复杂动态场景的实时绘制效率得到明显提高.

| Abstract: | An efficient visibility culling method was presented for dynamic models of complex products in virtual assembly.By this method,the product assembly tree was represented using a BVH scene graph.During the rendering stage,a strategy was proposed in order to improve occlusion query efficiency.Combining with VFC and detail-culling,the visibility culling method for virtual assembly was realized.Experiments show that the method can efficiently cull small-pixels parts of dynamic models in virtual assembly,thus gre... |
