Development stage lighting simulation system is of great significance for the work of stage lighting design, stage model is various, for different stage, the need to the corresponding lighting design. So, in the process of stage lighting design work will have a lot of uncertainty. In this article, through the simulation stage lighting effect, can reduce energy and time.
 
The stage lighting virtual design and implementation effect
 
Through the use of the OGRE engine architecture, can more easily simulate lifelike three-dimensional lighting environment, immersive and interactive ability of the virtual technology itself has not only the static design and creation can be transformed to a dynamic form of reproduction, but also in a timely manner to capture and show the designer's ideas, creativity and inspiration, a mature and perfect platform for the virtual design system for lighting designers, performance director, lighting control operator, or for lighting lighting art teaching and do a presentation, etc is a very professional and practical design tools and right-hand man. And convenient real-time interactive function, make the system more real-time and operability. This system provides a real-time interactive operating environment, meet the needs of the user.
 
A, the system architecture
 
1. The logical architecture
 
Both games and virtual reality, in order to show its lifelike, most virtual scene is more complex, so most of the virtual scene creating generated by 3 d modeling tool, and then to the scene real-time rendering output. Stage lighting design provided by the 3 on3dmax basic scene file, through the DOM (Document Object Model) interface for parsing, and carry on the import and the scene of the resources. Eventually into the OGRE
System for rendering.
 
Illumination model is a variety of, need to achieve their effects respectively in the scene. At the same time the user to be able to take with the UI interface for all kinds of operation. System requirements operation complexity is high, large amount of calculation and strong extensibility. Need to design and build a data processing and high calculation efficiency and strong extensibility, and functional module loose the cohesion and the overall implementation architecture of oa, system into the resource layer, interface layer, rendering layer.
 
Resource layer: from 3 + Ofusion on3dmax plug-in export, generate scene organization, material, entity, texture, etc required by the system resource files.
 
The interface layer: is responsible for the resource file import scenario.
 
Scene rendering layer: the implementation stage and the rendering of lamplight, the management of system resources, the real-time response of user interaction, etc.
