Abstract: A framework based on tile-pyramid model and linear quadtree tile-index is put forward for the real-time visualization of massive terrain dataset.The real-time loading of terrain dataset is achieved by employment of the view frustum culling technology and the target-tile searching algorithm based on resolution-testing.The dynamic binary tree triangulation is used for the real-time rendering of the terrain tiles.The experimental results show that this framework can achieve good performance for real-time rendering of massive terrain dataset running on the current personal computers.
