A new algorithm for interactive rendering of huge point-sampled geometry based on view-dependent level-of-detail(LOD) and out-of-core techniques is presented.

Firstly, a hierarchical quadtree-based method of organizing the data of ground objects in a large area was proposed; Secondly, the interactive rendering process of ground objects in a large area was introduced, and the steps of view-frustum culling of quadtree nodes and occlusion culling were described particularly.

The technologies,such as real-time interactive controlling,dynamic simulation,which are employed to express varies of change during machining process,were detailed.

Modeling and real-time rendering complex virtual scene of hydraulic engineering;

Research on real-time rendering algorithm in ship visual scenes;

Cloud simulation and real-time rendering for flight simulation;

Per Vertex Lighting has been employed many years in common for real time rendering.

To investigate real time rendering of terrain surface, improve the speed of rendering and the fidelity of simplification, the algorithm taking the distance from vertex to average plane as the error metric and progressive meshes based dynamic simplification was used, which provided view dependent simplification of the model.

The efficient visibility culling method is one of the important research aspects of real time rendering of complexle dynamic scene.

Objective To satisfy different observational demands, a real-time interactive volume rendering for laser scanning confocal microscope (LSCM) image was realized on the PC.
