Formation method and system of role model

Abstract

The invention relates to a role model formation method. When bone models and bone levels of a role model are established, a bone is added through extending the hip to a back portion of the bone model and is taken as an extra hip bone; the level of the extra hip bone is a father level of the level of the hip; motion capturing data at the hip is bound with the role model, the motion capturing data is separated to acquire displacement data and rotation data, the displacement data is added to the level of the extra hip bone, and the rotation data is added to the level of the hip. Through the method, displacement deviation and motion deviation caused by center-of-gravity deviation can be effectively eliminated, and motion abnormity in cartoons can be avoided. The invention further provides a role model formation system.

Description

technical field [0001] The invention relates to the field of animation production, in particular to a method for forming a role model and a system for forming a role model. Background technique [0002] The pre-animation production work includes character setting, character model building, character rigging (binding) and animation setting. Among them, the assembly of characters is an important link in the process, and it is an important means to endow characters with individuality. A good hierarchical (skeletal hierarchy) relationship in character rigging can help animators efficiently complete animation rigging. The so-called hierarchical relationship is the hierarchical structure system, which is a powerful means of making computer animation. It can clearly reflect the relationship between the bones in the character rig. Object linking forms a hierarchy by linking one object to another to create a parent-child relationship. The transformation applied to the parent object...

However, for the motion recording of the hip (HIPS, the control point for the overall displacement and rotation of the skeletal model), usually the tracker of the motion capture system is set at the coccyx of the motion capture actor, and when the motion capture data is superimposed on the 3D modeling and In the character model of the animation software (the bone with the controller in the software), the data recorded by the tracker at the coccyx is placed in the hip of the character model, resulting in a deviation of the center of gravity, see Image 6

When the actor is doing the action, it will cause abnormal movement in the animation, which will increase the modification work of the animator in the later stage; for example, when the actor is standing still or squatting down, the upper half of the character model will appear backward
