A Simple Multi-Models Rendering Framework - PM-OCMMRF

We presented a new framework for dynamic level of detail rendering of multi-models. Our framework adopts LOD control on every single model, and keeps low screen errors. Firstly, we introduce a new simple and efficient implementation of PM which is used to save memory and CPU resource. Secondly, we try to optimize all models by combining progressive mesh with occlusion culling. At last, we promote a view-dependent level of detail rendering system by technics such as frustum culling, LOD control, reservation of resource, GPU cache and so on. Experiments show that this simple framework which is named PM-OCMMRF (Progressive Mesh-Occlusion Culling combined Multi-Models Rendering Framework) values a lot in applications of rendering multi-models.
