The Design And Implementation Of Virtual Reality System For Theme Hotel Rooms Based On Web3D

With the increasing of residents' disposable income, this kind of theme hotel established on a higher comsumption level while with a batter experience has been gradually recognized by the market. How to show the intelligent and uniqueness of theme hotel is a problem that puzzled the whole industry. Most of the solutions on the market at present is to use the "360- degree panorama" to show rooms, but this method has many defects in interactivity and experiential. Aiming at these deficiencies, this paper designed and developed a set of virtual reality system of theme hotel rooms which based on the Web3 D, allows users to experience the rooms in the form of roaming in the first view point, and display new themod of controlling room lighting, air conditioning and background music simply using APP in a strong interactive way, providing a new solution to display the theme hotel.Display of high quality images in real-time is one of the key factors to measure system usability and user experience. So, aiming at real-time rendering of hotel room scene, this paper deeply studied of geometry organization, optimization management, and the mechanism of collision detection of 3D scenes, and achieved three hierarchical bounding box collision detection algorithm based on OpenGL and loose octree scene management algorithm in the Unity3 D.Innovation of this paper lies in: in order to satisfy the requirements of the system real-time rendering, the loose octree scene management algorithm is optimized oriented to theme hotel room scene. Objects in the scene are placed in more suitable node under optimized algorithm, enhances the precision of scene storage, makes this algorithm more suitable for complex scenes with more detail like the hotel rooms, thus reducing “useless render” on the edge of frustum while operating visibility culling, finally meet the requirements for graphics rendering system in real-time.On the basis of the above key algorithms were studied and solved, this paper has carried on the other system function design, in order to realize the complete function system. Specifically, this paper established the theme hotel rooms model using 3dsMax and imported it into Unity3 D, scene roaming and the interaction function such as the control of light, air conditioning setting of temperature, and background music selection were all developed in Unity3D;respectively using the PHP language and Bootstrap fram to develop back-end logic and front-end web framework, implements user functions such as query prices, reviews, ratings,and management functions like comment management, room management, user management.
