Skin-top affecting weight distribution method based on standby joint point collection

Abstract

The method includes steps: (1) vertex normal projection, i.e. spot projecting all skin vertexes and prepared articulation points to be selected onto normal direction of parallel intercepted plane in concentration; (2) dividing the said articulation points, and attaching two adjacent articulation points to divided skin vertexes; (3) attaching determined articulation points to skin vertexes; (4) according to sorting rules, sorting skin vertexes; according to relation between skin vertexes and positions of two affected articulation points, setting up class attribute of vertex, and adjusting accessory affected articulation points according to adjusting strategy; (5) setting up weight value of affected articulation points on skin vertexes including three classes. The invention saves manual labor for modeling, as well as raises automatic degree in procedure for geometrical modeling virtual human and in matching procedure between geometrical model of virtual human and moving data framework.

Description

technical field [0001] The invention belongs to the technical fields of computer virtual reality and computer graphics, and in particular relates to a virtual human skeleton animation technology and a skin deformation technology in the virtual skeleton animation. Background technique [0002] Virtual human technology, especially virtual human animation technology (character animation technology) is more and more widely used in virtual reality systems, distributed virtual reality systems, computer character animation, 3D games, digital film technology and other fields. In virtual reality, especially in distributed virtual reality systems, it is required that the virtual human controlled by humans has a certain degree of realistic geometric model, and at the same time, it can simulate part of human actions in the real environment in a natural and realistic way, so that operators and observers The user can obtain a certain degree of immersion. In the field of character animati...

Problems solved by technology

[0007] The implementation of the above skeletal animation requires the model and the collected motion data to use the same set of skeleton structures, but in fact the two processes of modeling and collecting motion data are relatively independent, so a large number of established virtual human models or No skeleton structure is attached, or the attached skeleton does not match the skeleton definition of the motion data to be used, which will have a certain impact on the application of skeletal animation
