Development Of Chemical Technology Scene Graphics Simulation Common Tools

Visual simulation (VS) is a technique, which creates the simulation analysis environment by visibly processing data or other form information. People can master variably relation between variable and variable, variable and parameter, variable and foreign effect to directly comprehend static and dynamic system character through visual information. It is to summarize common element and structure law, and to make visibly outputting of simulation separate software system studying Visual Simulation tools. Moreover, it is make chemical model simulation input straight and output visualized using computer graphics image technique studying the interactive chemical technology scene Visual Simulation tools.With guide of software engineering, computer graphics, simulation theory, this paper make a study of chemical technology scene Visual Simulation platform in realization and theory. The idea of "open structure of Visual Simulation platform", " physics animator", " 3D dynamic interactive", "date drive " and resolvent are presented, conformed in unit operation as well.About construct of chemical technology scene Visual Simulation platform Open design of system structure in software and hardware of chemical technology scene Visual Simulation platform is resolved using distributing simulation and software component and architecture theory. Realization method and technology standard is givenStudying movement rule of chemical technology scene, the paper presents the conception of "physics graphics animation" differing from custom animation-key frame animation. The realization of physics animator is also given with the support of OpenGL. On the basis of above, the paper study 3D dynamic interactive and resolve it by method of "Two-dimension selecting " idea. Suggested by texture transposition, the new method is advanced by which background system with character of "panoramic vagabondize " is come true.This paper present conception of "date driver ". Diversified commutation method is studied with support of DLL, ActiveX, ADO. Connection and visitation to various data source is resolved by creating commutation component and data interface sever.Finally, how to perfect the Visual Simulation (VS) system, expand system fromVisual Simulation to Multimedia Simulation (MS) and Visual Simulation to Virtue Reality (VR) is conceived.
