Traditional preprocessing methods, such as discrete Levels Of Detail (LOD) or continuous LOD, are inapplicable to large dataset consists of huge amount of models. Division granularity of discrete LOD is coarse while continuous LOD is time-consuming. Real-time rendering is a challenging and open problem to solve. A real-time rendering method to solve preprocessing problem in huge dataset based on pre-computed hierarchical levels of detail is proposed by different granularity and hierarchy division. Experimental result shows that the proposed method is more suitable for huge dataset.
