Bone flexible-body realization method and device and electronic equipment

Abstract

The embodiment of the invention provides a bone flexible-body realization method and device and electronic equipment. The method includes: creating a bone joint tree corresponding to a target object,wherein the bone joint tree is formed by multiple bones; for each bone with a father bone thereof, obtaining a current-frame position and a next-frame position of the bone, and obtaining a current-frame position and a next-frame position of the father bone of the bone; calculating and obtaining the amount of rotation of the bone relative to the father bone according to the current-frame position and the next-frame position of the bone and the current-frame position and the next-frame position of the father bone; and controlling a bone chain between the bone and the father bone to rotate aroundthe father bone according to the amount of rotation to enable the bone to move from the current-frame position to the next-frame position. According to the bone flexible-body realization scheme, movement of the bone is converted into rotation of the bone and the bone chain before the father bone, massive calculation overheads caused by one-by-one calculation on vertices in the prior art are avoided, and running efficiency of a flexible body is improved.

Description

technical field [0001] The present invention relates to the technical field of computer animation, in particular to a method, device and electronic equipment for realizing a skeletal flexible body. Background technique [0002] The use of soft bodies in 3D games can improve the reality and performance of the picture, such as cloth and hair fluttering in the wind. Because the movement of the soft body is based on the result of real physical calculations, its picture performance is very real. Compared with normal skeletal animation, skeletal animation is an effect adjusted by the art in advance, no matter how the character moves, it will be presented in front of the player. It is a definite result, and the soft body will show different results with different movements of the character. It is calculated based on real physics and can bring better performance. [0003] In the prior art, the way to realize the skeletal flexible body is to calculate the physical position of each v...

Problems solved by technology

Although GPU-accelerated computing solutions are currently provided, there are many protagonists visible on the same screen in large-scale online games, which may reach hundreds of people, and each protagonist will have many soft body models. This kind of calculation is unbearable for ordinary computers.
