| Abstract: |
| The real time display of 3D complex models，which is widely used in flight stimulation，scientific computing visualization and architecture walkthrough，is becoming one of the most challenging issues in Computer Graphics．In this paper．the authors have developed several efficient techniques to perform real time display，including multi—reso lution model，hierarchical model，instancing，visibility determination，texture mapping，levels switching and controlling and so on．These techniques have been successfully ap-plied to the information management and decision support system of Yuxi Cigarette Facto ry．Finally，the result is given and the future work is presented． |
