Polygonal meshes dominate the representations of 3D graphics models due to their compactness and simplicity. Recent advances in design, modeling, and acquisition technologies have simplified the generation of 3D models, which have led to the generation of large 3D models. These models consist of millions of polygons and often exceed the rendering capabilities of advanced graphics hardware. Therefore, there is a need to reduce the complexity of these models to match the hardware's rendering capability, while maintaining their visual appearance. Numerous algorithms have been developed to reduce the complexity of graphics models. These include level-of-detail rendering with multi-resolution hierarchies, occlusion culling, and image-based rendering.

View-dependent rendering approaches change the mesh structure at each frame to adapt to the appropriate level of detail. Traditional view-dependent rendering algorithms rely on the CPU to extract a level-of-detail representation. However, within the duration of a single frame, the CPU often fails to extract the frame's geometry. This limitation usually results in unacceptably low frame rates. In this presentation I will present new approaches for interactive view-dependent rendering of large polygonal datasets, which use the advanced features of modern graphics hardware, and free the CPU.
