Embodiment Construction

[0022] Those skilled in the art understand that in the prior art, when voxelizing a grid model into voxels, a simple intersection judgment method is generally used. For example, by determining whether the patch in the mesh model intersects with a voxel unit in the voxel, it is judged whether the voxel unit needs to be marked, and the set of all marked voxel units in the voxel can be used to represent Voxelized mesh model. If the user wants to accurately display the details of the mesh model in voxels, it is necessary to set the voxel unit as small as possible, and ensure that the details of the mesh model can be accurately voxelized by refining the voxel granularity , however, such a solution will greatly increase the data calculation amount of the computer, seriously affect the voxelization efficiency of the computer, and is not conducive to the user's operating experience.

[0023] In order to solve the above technical problems, the technical solution of the present inventi...

Abstract

Provided is a grid model voxelization method and apparatus. The method includes the following steps of acquiring a grid model; determining a plurality of voxel units and preprocessing at a part of the grid model according to the preset voxelization parameters to obtain the pre-facet list of each voxel unit; processing the pre-facet list of each voxel unit to obtain a preferable facet list set, the preferable facet list set of each voxel unit includes at least one preferable facet list to express that at least one facet in the pre-facet list is included in the voxel unit; acquiring the total facet list of a single voxel grid according to the preferable facet list set of each voxel unit; acquiring the total facet list according to the total facet list of their respective single voxel grids of the plurality of voxel units, the total facet list is used for forming the corresponding voxels of the grid model after the voxelization. The grid model voxelization method and apparatus can completely guarantee all of the details of the grid model in the voxelization result in an accurate, efficient and robustness manner.

Description

technical field [0001] The invention relates to the field of computer graphics processing, in particular to a voxelization method and device for a grid model. Background technique [0002] Computer graphics is a discipline that establishes a mathematical model of the real world and calculates the light and shadow effects of the mathematical model based on the computer to display images on the display device. With the rapid development of computer technology, computer graphics has been more and more applied to fields such as film and television special effects, advertising, animation, computer games, military simulation, medical imaging, etc., and has become the core technology for displaying images. Modeling is a basic problem in computer graphics, which is used to study the representation of three-dimensional objects. [0003] At present, the mainstream modeling technology in the industry uses voxels or polygonal grids to represent 3D models for applications in 3D imaging,...
