Embodiment Construction
[0034] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] figure 1 It is a flowchart of a method for generating a multi-level-of-detail grid according to the present invention, which will be referred to below figure 1 , the method for generating a multi-level-of-detail grid of the present invention is described in detail.
[0036] First, in step 101, the voxel data is down-sampled.
[0037] In this step, the voxel data is down-sampled to generate voxel data and additional information required by other levels of LOD.
[0038] When downsampling is performed on voxel data, the basis for downsampling is eight adjacent voxels, which become one voxel after downsampling. A conservative downsampling method is used here, ...
