Virtual Reality Environments Natural Light Method Based On Real-time Rendering

Due to the rapid development of the computer in the new multimedia environment, there are many methods such as model scanning technology, material scanning technology, motion capture technology, expression capture technology and so on, how to truly rebuild the virtual environment and things, cluster rendering farm In various places, various fields of vigorous development. However, the real-time rendering technology in virtual reality is still the subject of computer art at this stage. Therefore, how to achieve high-quality real-time rendering in virtual reality content development has become the focus of research in recent years.Simulation of light and shadow on the virtual scene of the real or not played a very important role. As the special properties of light, with the temperature, air pressure, humidity, seasonal, time changes have different changes in the simulation of light generated a great challenge, a slight decline in quality, and refresh rate is too low will allow users to Authenticity of doubt, reduce the sense of immersion. But in order to achieve the real, first of all, the real-time rendering of light and shadow on the speed and quality is very high. But also on the diffuse reflection, light reflection, the refraction between objects, atmosphere and interactive features of the virtual reality, a lot of calculation, with the previous rendering technology is difficult to run in real-time computer on the ordinary.At present, the mainstream of the film rendering is through the mainstream rendering software through the cpu of the image data, the calculation speed can not achieve the real-time rendering required by virtual reality and because the rendering volume is already very large, if the scene has more details and More interactive, for the traditional software rendering is not possible, and the early game engine due to technical and hardware bottlenecks can not be complex virtual reality scene rendering, can only be used in a simple interactive platform, can not achieve the use of Of the virtual world tour requirements.In this paper, the illusion of the game engine with MAYA, photoshop and other graphics software combined with complex real-time rendering of virtual reality scenes optimized. The real-time rendering optimization of complex scenes with real-time tour and interactive light source is realized by using the model to simplify the unstructured segment, the texture diversification switch, the virtual engine blueprint design, the delay illumination and the control light source. Combined with HDR technology and delayed illumination model, the corresponding shaderprogram, Realizes the real-time tour and interactive effect of the scene, and finally applies the optimized process to real-time indoor interactive tour, and makes reference to the development of virtual reality content at this stage.
