| This paper is base on the 3D Desktop system, it handle and manage the space and solid Desktop system, this system use for reference the handing and managing to man-machine conversation 2D Desktop system, do some in-depth research, make the 3D Desktop system be more ability and practicability.On the 3D Desktop, man-machine conversation is the important instrument for conversation between user and computer. The research of man-machine conversation mechanism is belong to the exploitation of 3D Desktop system in this paper, the important task for this research is introducing the basic theory about how to sort 3D cursor and 3D mouse, design a suit of mechanism for alternation base on sorting 3D mouse and OpenGL, and give the exhibition of romance mechanism, dealing with message mechanism, dealing with data flow and control correspond module particularly in the condition of 3D.This paper analysis the exploiters idea and structure of design tool of MFC interface device and CEGUI device, combine the sort theory of 3D mouse and OpenGL, use QT core signal and slot mechanism, define the communication interface be aimed at 3D Desktop system, devise and achieve a-sort of user-defined communicate mechanism among the objects of 3D Desktop system.Alternation mechanism is satisfying the man-machine conversation and protect, we must set up the geometry construct and 3D model for it. This paper bring forward a sort of policy be able to optimize the alternation model, decrease the number of module of alternation operate, such as the number of net triangular when modeling the menu and dialog box, advance the efficiency of system to read and protract model.The interaction system links the 3Dvirtual sense with the underlying computer, and it can reach real time control of the program installed in the operate system automatically and can configure the operate system.This paper also gives a design of UI warehouse of controls. Keywords:3D Desktop Interaction module OpenGL SDL... |
