摘要
基于VRML建立大范围、多景物的场景,通过Web进行浏览时存在着网络带宽和绘制困难的问题。本文把大范围的场景分成许多矩形场景块,通过ProximitySensor、VisibilitySensor节点和Javascript调度场景块,使每次调入的场景块数量尽可能的少,能在一定程度上克服上述问题。
When we browse over a wide - field with multiobject scenery on the Web, we have to tackle two problems. Firstly, the network bandwidth is limited; and secondly, it is difficult in rendering. In this paper, we partition the wide field into many rectangle blocks, and dispatch it with ProximitySensor,VisibilitySensor and Javascript, so as to make the number of folding scene blocks as less as possible in each time. The problems can thus be overcome partly.
