Abstract

The invention discloses a dynamic bone implementation method and device in an animation. The implementation method comprises the steps of creating a bone joint tree in allusion to a target object, wherein the joint, which is closer to a root node, in two directly connected joints in the bone joint tree, is a parent joint, and the joint, which is far away from the root node, is a sub joint; calculating location information of joints in the bone joint tree in the next frame; and in allusion to at least one sub joint in the bone joint tree, converting location transformation of the sub joint from the current frame to the next frame into rotation transformation of the sub joint around the parent joint of the sub joint, and thus moving the sub joint to the position in the next frame through rotation transformation. Therefore, the moving process is enabled to be smoother through converting location transformation of a joint into rotation transformation around a parent joint thereof, and the visual experience is improved.

Description

technical field [0001] The invention relates to the technical field of computer animation, in particular to a method and device for realizing dynamic bones in animation. Background technique [0002] Actions such as walking, running, and attacking characters in the game are essential, and the method of realizing them generally adopts frame animation or skeletal animation. The difference between frame animation and skeletal animation is that each frame of frame animation is a snapshot of a character's specific pose, and the smoothness and smoothness of animation depends on the number of frames. The skeletal animation is an animation generated by binding the pictures of various parts of the character's body parts to the "bones" that interact and connect, and controlling the position, rotation direction, and zoom in and out of these bones. [0003] In the process of 3D game development, the action performance of the character model is usually realized by using bone skin animat...
