Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] see Figure 1 to Figure 4 , the present invention provides a method for realizing the action of a virtual character grasping a target object, which is realized according to the following steps:

[0039] Step S1, initialization, analyzing the human skeleton of the virtual character, displaying the maximum limit value of the model's palm grip recorded by the skeleton on the model, and then recording the quaternion rotation value of each finger joint bone of both hands;

[0040] Step S2, obtain finger data, search for the mesh model bound to the left hand and right hand on the avatar; traverse all the vertices bound to each finger joint bone on the mesh model, establish a vertex dictionary and use the bone as the key to divide the vertices according to the bone Classify and store; traverse the grid position of all vertices in the vertex dictionary, and obtain the ...

Abstract

The invention relates to a method and a system for realizing a target object grasping action of a virtual character, and the method comprises the following steps: S1, initialization, S2, finger data acquisition, S3, finger collision body calculation, S4, target object collision body calculation, S5, grasping action calculation, S6, a grasping action realization module, comprising: carrying out difference processing on the recorded grasping data and the current action according to a set weight value; and applying the processed data to the virtual character model. According to the scheme, the hand shape action that the hand grabs any object is automatically calculated. The 3D animation or game for realizing the grabbing action of the virtual character does not need to make the hand-shaped action for grabbing the object in the production process. In addition, due to the fact that the mechanism of automatically calculating the hand shape according to the shape of the object can be achieved, the size of the grabbed object does not need to be standardized, and the richness of the grabbed object is enhanced.

Description

technical field [0001] The invention relates to the technical field of virtual character action execution, in particular to a method and system for realizing the action of a virtual character grasping a target object. Background technique [0002] At present, the method for realizing the virtual character's grasping of the object is the hand grasping animation edited by the software used. The disadvantage of this solution is that manpower is required for animation editing, and the size of the captured objects must be standardized. Otherwise, using the same hand grabbing action will produce the effect of piercing. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a method for realizing the action of a virtual character grasping a target object, so that the virtual character can grasp the target object without wearing a hand. [0004] In the embodiment of the present invention, the following solutions...
