The scene model is extremely complex in the 3DVR remote control platform for shearer. In order to speed up the 3D scene rendering of 3DVR remote control platform for shearer and reduce computational load of the system, we simplified the scene model based on LOD technology. The LOD algorithm was designed, in which the computing method of simplification rate, the algorithm of Triangle mesh simplification based on contraction and data structure of original mesh was described. Two shearer drums were simulated in the XNA platform via the above method. The simulation experiment results show that LOD model generated by the LOD algorithm have almost no loss in the visual effect, meanwhile the complexity of the scene model is reduced and the scene rendering speed is improved.
