Embodiment Construction

[0062] Below in conjunction with accompanying drawing and example the present invention is described in further detail:

[0063] The present invention is applied to the visual simulation of virtual soldiers in a virtual battlefield environment. The bottom layer of the client system is the data layer, which provides a basic behavior library supporting the actions of virtual soldiers; the second layer is the animation synthesis engine layer, which accepts and parses the The command flow from the virtual soldier is generated by animation transition and hybrid algorithm; the third layer is the OpenGL graphics rendering layer, which displays the rendering result of the virtual soldier's 3D geometric model and outputs it on the screen.

[0064] The implementation process of the invention includes four main steps: constructing a motion combination relation table, command flow analysis and motion file sequence generation, motion data mixing and animation interpolation playing.

Abstract

The invention discloses a command stream based three-dimensional character animation synthesis method. The method comprises the steps of firstly performing classified description on character action models according to moving states, whole body postures and upper body postures; prefabricating specific three-dimensional animation files according to a combination relation table of action classification; building a distributed client/server network model, and formulating protocol specifications for datagram transmission; and searching the combination relation table of action combination by a client after parsing a command data stream transmitted by a server, acquiring relevant action files, and synthesizing a new animation sequence after performing motion blending and performing interpolation on the location and the orientation of a character. According to the invention, automatic switching between difference actions of virtual soldiers in a virtual battlefield environment can be reproduced authentically, smooth interpolation update of the position and the orientation of virtual characters is supported at the same time, a problem of combination explosion between the tedious command control process and actions is avoided, action switching is performed smoothly and naturally, and the method can be widely applied to various virtual battlefields. Therefore, the command stream based three-dimensional character animation synthesis method has a certain application value.

Description

technical field [0001] The invention relates to the technical field of computer virtual reality, in particular to an animation synthesis method of a three-dimensional character based on command flow. Background technique [0002] Virtual reality technology originated in the aerospace and military sectors. With the rapid development of the new military transformation centered on information technology in the century, the application requirements in the military field have put forward higher requirements for virtual reality technology, which has promoted and promoted the gradual maturity of the technology. At the same time, the development of network and virtual reality technology has made military exercises and combat styles different from traditional warfare in terms of concepts and methods, and have been more and more widely used. Virtual reality technology is safe and non-destructive, consumes less resources than actual combat exercises, is not limited by natural condition...
