Method for realizing man-machine interaction on three-dimensional animation engine lower layer

Abstract

The invention discloses a method for realizing man-machine interaction on a three-dimensional animation engine lower layer. The method includes the steps: uniformly packaging pickup, translation, rotation and scaling operation by the aid of an event processing object to respectively form event response functions; defining working states, corresponding to different types of operation and the event response functions, of the event processing object by the aid of enumerative variables based on a finite-state machine; and receiving an interactive event triggered by a user, leading the finite-state machine to skip to the working state corresponding to interactive event and executing the corresponding event response function. A man-machine interaction function for roles in a scene can be realized by means of simple management of the finite-state machine, and difficulty in designing the lower layer for man-machine interaction in the three-dimensional engine design is simplified.

Description

Technical field [0001] The invention relates to the field of three-dimensional animation engine design and three-dimensional graphics in the computer animation industry, in particular to a method for realizing human-computer interaction at the bottom of the three-dimensional animation engine. Background technique [0002] With the development of virtual reality, distributed visual computing, distributed simulation and online 3D games, 3D animation engine has become an indispensable part of 3D animation development. 3D animation design not only requires the model to be highly realistic in graphics and have real-time response capabilities, It also requires the model to have physical properties and behavioral capabilities (that is, the model can move autonomously according to objective laws). If all these designs are developed from the bottom, the workload is conceivable. The realization of human-computer interaction is the most critical part of the bottom layer of the 3D animation ...

AI Technical Summary

Problems solved by technology

[0003] At present, the 3D engine technology based on human-computer interaction is still under development. Although some companies have more mature technologies, such as 3ds Max, Maya, etc., because these 3D engine software completely encapsulates the underlying human-computer interaction implementation, it is only left to the supplier. The user calls the upper interface of the human-computer interaction function, which is more convenient for the use of ordinary 3D engine software, but for users who need to use the specific functions of the 3D engine, it is necessary to develop a set of specific software combined with the human-computer interaction function of the 3D engine

At the same time, the cost of commercial use of existing mature large-scale software is relatively high. For users who do not need too many complex function support, low-cost software that meets specific needs can be developed for use.

[0004] It can be seen that in the prior art, there is no method for implementing function encapsulation and calling by the upper layer for human-computer interaction at the bottom layer of the 3D animation engine through the bottom layer algorithm.
