Three-dimensional garment and human model collision detection method and device

Abstract

The invention provides a three-dimensional garment and human model collision detection method and device. The method comprises the steps that a three-dimensional garment pattern piece corresponding to a to-be-displayed garment and a three-dimensional human model are obtained; collision parameters of all discrete grid points in the three-dimensional garment pattern piece are obtained, and a mass spring model corresponding to the three-dimensional garment pattern piece is built; when the mass spring model is moved to the collision position matched with the three-dimensional human model, collision detection is conducted on the mass spring model and the three-dimensional human model according to an algorithm of the bounding box tree to determine whether the three-dimensional garment pattern piece is actually attached to the three-dimensional human model or not. In this way, the display effect of the to-be-displayed garment on the three-dimensional human model is more vivid and truer; meanwhile, by means of the algorithm of the bounding box tree, collision detection between the three-dimensional garment pattern piece and the three-dimensional human model can be completed rapidly, and the real-time property of the whole process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer-aided garment modeling, in particular to a collision detection method and device for a three-dimensional garment and a human body model. Background technique [0002] Based on the rapid development of virtual reality technology, people are eager to simulate the real world. For the current online clothing consumers, they not only want to see the standard style of the clothing worn on the model, but also want to see the real effect of the clothing worn on themselves, so as to choose the style, model and color of the clothing in a targeted manner Collocation, the overall shape. [0003] At present, based on computer-aided clothing modeling technology, it is to wear clothing on models made in advance by computer software, specifically including: obtaining 3D clothing patterns and 3D human body models, and then manually moving the 3D clothing patterns to Finally, the clothing is displayed on the thr...

Problems solved by technology

[0004] However, in the matching process between the 3D clothing pattern and the 3D human body model achieved by the above manual method, the effect of clothing displayed on the 3D human body model is not accurate due to errors in the manual operation
