Research of Dynamic Generation for Terrain and Dredging Cutter
The paper introduces the system for dynamic generation of terrain and dredging cutter in work. The model of dredging cutter and the method of calculating the soil quantity are emphasized. 3D terrain is rendered by point pattern and grid model, represented by LOD(Level of Detail). Besides, the cutter model and its implicit equation are built. The collision between terrain grid and the dredging cutter is quickly detected by the cutter boundary box so that dynamic change of terrain and the soil quantity are solved effectively when the cutter sucks the soil. The experiment results show that the method can meet the real-time change of terrain and the accuracy of the soil quantity.
