By the analysis to the complex scene,a double-layer visibility culling algorithm is proposed,and the algorithm combines view frustum culling,detail culling and occlusion culling methods.

Some key technologies are discussed,such as the modeling and optimizing of cosmically and complex scene,scene database optimizing,the showing and optimizing of CAD models,the optimizing of data structures.

The complex scene of the block scheduling strategy and its improvement programme are discussed,and it is applyed to "the virtual training system of station" ,soluted the "jump flash" phenomenon in the block scheduling strategy.

A Fast Soft Shadows Algorithm for Dynamic Scene in MMOG

An algorithm is proposed in the paper to extract video object from dynamic scene based on motion estimation and the graph pyramid.

And then the paper introduces loose octree into dynamic scene organization and puts forward the concept of data dispatching pipeline.

Dynamic scenes generation system based on image database;

The rendering of dynamic scenes in terrain environment is studied.

Second, according to dynamic scenes rendering, we research update algorithms on accelerators, try to make accelerators in every frame can be reuse by next frame without restructuring, so we can save the restructuring time which takes a majority of render time.
