Generation And Verification System Of3D Scene Based On Script

Virtual reality can simulate the reality environment that makes people have immersed sense. As techenolgy develops, the simulated environment is more and more lifelike, which requires better3d scene file. The model is fine and there are a lot of types of model data. The problem comes up that how to merge different types of model data into scene file.The requirement of the scene structure is also change. It always needs different scene structure for different application. It is quite inefficient to write code to generate and verify the scene for each application. During the same application, It needs a lot of scene file for debug and test. So how to generate scene file of different structure quickly and efficient is also problem.We propose a new way to generate and verify the scene which is based on scripting language. Scripting language simplify the process of development, deployment, test and debug. It is not only easy to deploy but also simple, easy to learn and use. These traits make it it the work of scene file generation and verification. When the scene structure changes, we only needs to change script. This is quite suitable for generation and verication of3d scene file.We design a set of simple script command and clearify the function and schema of each command. In order to add new command to the command set in feature easily, we come up a good framework. Based on script command set, we implement the generation and verification system. During implementing the generation system, we come up a good framework for satisfying mulity-types of model data, and this framework is easy to support new model data type. Verification system is able to verify the scene according to different scene structure of different application. After the verification, the scene is a right input and the application can run.The whole system is not only extionalbe but also flexible, which can reach the target to generate and verify scene quickly.
