A Virtual Reality System for Automation Assisted Interior Design

Abstract

With the economic development and people's growing demand for a better life, the proportion of home decoration market in the economic market is also gradually rising. However, under the impact of the downturn of the general environment and the new mode of Internet, many offline home decoration companies cannot bear the heavy burden and are struggling in the market operation. For a variety of marketing methods of businesses, consumers have immunity, little effect, so home decoration technology needs to produce a new model in the Internet environment. Though combining virtual reality technology with interior design, a new intelligent automation interior design system based on VR technology is introduced. This paper introduces the design and implementation of virtual system for interior design, and analyzes the key technologies of VR application. The main design idea of this system is to automatically design a perfect indoor layout with lighting effect, reflection effect and visual effect as the technical indicators according to different room types, including the functions of importing CAD drawings to dynamically create houses, automatically calculating scene layout, and accepting user interaction to change the design. In the specific implementation process, through the improved LOD technology, that is, according to the characteristics of VR scene, focus on rendering objects in the first person perspective, for all kinds of actors out of the perspective of high LOD optimization, PBR Technology (Physics Based Rendering Technology), combined pre-rendering and real-time Rendering can not only avoid the influence of the first person perspective effect caused by the general global rendering of the scene, but also avoid the high cost of computer performance caused by the rendering process.
