Problems solved by technology

If OBB is used, the problem of inaccurate judgment can be avoided to a certain extent, but OBB still has the problem that each frame needs to be dynamically generated according to the character's pose and animation, and the cost is relatively high.

Embodiment Construction

[0025] In order to make the technical principles, features and technical effects of the technical solution of the present application clearer, the technical solution of the present application will be described in detail below in conjunction with specific embodiments.

[0026] In 3D graphics simulation, character modeling is divided into two parts, the first is to create the skeleton of the character, and then the skinning operation is performed on the basis of the skeleton. Such as figure 1 As shown, multiple triangles constitute the character skeleton, and the model is the skin based on the skeleton. After the character modeling is completed, the 3D graphics engine drives the bone position change, and then drives the skin model to change, and finally forms the effect of the character making various actions.

[0027] According to the principle of character modeling in 3D graphics simulation, this application proposes the following collision detection scheme:

[0028] Body p...

Abstract

The invention discloses a collision judgment method. The collision judgment method includes the steps that firstly, the portions, needing collision judgment, of the bodies of roles are determined; secondly, each portion is provided with at least one spherical surrounding box, and the spherical surrounding boxes are bound to bones of the roles; thirdly, the spherical surrounding boxes move along with motion of the bones, and whether the spherical surrounding boxes collide with other objects or not is judged in the motion process. By the adoption of the scheme, collision of the specific portions of the bodies can be accurately described, and collision computing cost is low.

Description

technical field [0001] The present application relates to the technical field of computer virtual reality, and in particular to a collision determination method. Background technique [0002] At present, in order to achieve the purpose of improving the user's sense of game substitution, most games use various technical means to improve the degree of game simulation reality and bring users a more realistic game experience. Especially for action and fighting games, the most important way to improve the sense of game substitution is to improve the accuracy of one party's judgment of the other's attack or defense action as much as possible during the character battle process, and obtain more accurate judgment results. This can not only bring users more and more realistic game experience, stimulate players' interest, but also become an inseparable and important part of the skill system of various types of games. [0003] The traditional collision detection method in the prior ar...
