The development of stage lighting simulation system for stage lighting design work has important significance, the stage model is varied, for different stage, need the corresponding lighting design. In this way, in the stage lighting design process, there will be a lot of uncertain factors. In this article, through the simulation of stage lighting effects, can reduce energy and time of investment.

Guangzhou stage lighting through the use of OGRE engine architecture, can be more convenient to simulate realistic three-dimensional stage lighting environment, virtual technology itself has the ability to spot and interactive capabilities not only can be static design and creation into a dynamic form of reproduction, but also to capture and display the designer's ideas, creativity and inspiration, a mature and perfect virtual design system platform for lighting designers, performance director, lighting control operator, or for lighting and lighting effects are a very professional and practical design tools and powerful assistant. And real-time interactive features, the system makes the system more real-time and operability. This system provides a real-time interactive operating environment, to meet the needs of users.

First, system architecture

1 logical framework

Whether games or virtual reality, in order to show their fidelity, the virtual scene is more complex, so the creation of the virtual scene is mostly generated by the 3D modeling tool, and then the scene real-time rendering output. Stage lighting design by the 3DMAX to provide the basic scene file, through the DOM (Object Model Document) interface for analysis, and the introduction of resources and the organization of the scene. Eventually entered OGRE

System rendering.

The illumination model is varied, and it is needed to realize their effect in the scene. At the same time, users should be able to perform a variety of operations through the UI interface. System requirements of high complexity, large amount of computation, can be expanded. Need to design and build a data processing and computing efficiency, scalability, and functional modules loosely engage in a strong cohesion of the overall implementation structure (as shown in Figure 1), the system is divided into resource layer, interface layer, rendering layer.

Resource layer: the 3DMAX + Ofusion plugin is derived, generating the scene organization, material, entity, map, and other system required resources.

Interface layer: responsible for importing these resources into the scene.

Rendering layer: to realize the rendering of the scene and lighting, the management of system resources, and the real-time response of the user interaction.

System interface and summary

Three, system interface

System can achieve the stage of the handover, the stage of various scenes effect, but also with the stage scenes and various lights for real-time interaction. As shown in Figure 4 for the stage fireworks effect diagram, figure 5 is the volume light effect diagram.

Summary:

Stage lighting design has become a major problem for lighting designers. They often have to face such a high cost, high energy consumption and high time consuming problems. With the rapid development of information industry, professional stage lighting field has entered a comprehensive digital era. The system uses 0-GRE to build virtual stage, and the stage lighting design and adjustment for real-time rendering, while the stage lighting designers to provide a wealth of interactive features, can be a good solution to this problem. Next, the system also need to further enrich the stage lighting model, to simulate a wide variety of lights, such as: soft lights, flash, chasing lights. User interface also needs to be further optimized to improve the user friendliness of the operation.
