In order to meet the need of tire tracks visualization in dynamic terrain simulation, one GPU-based view-dependent continuous level of detail dynamic terrain rendering algorithm is proposed. The terrain deformation algorithm is executed in GPU memory, at the same time the tiled block quad-tree algorithm is used to render the deformed terrain. Different blocks are rendered with different level of detail by reusing a small vertex buffer and index buffer as well as different scale and bias factors. The skirt is added to each block's border to repair the potential cracks between neighboring blocks. The inquiry of the elevation is executed in the shader to collision detection. In the end, the experimental results show that our method is feasible and efficient.
