Scene decoration based real time interaction rendering method

Abstract

The invention provides a scene decoration based real time interaction rendering method. The method includes steps of construction and exporting of a model, model pre-treatment, model scenario setting,key model marking, model data flow transmission, WebGL flow type rendering and local caching. A camera is arranged in the center of a space environment and takes a plurality of scene photos continuously during a process of rotating 360 degrees in the space environment by taking 30-degree stepping as shooting points in sequence, and stores each scene photo. A contextual multi-core SVM scene identification algorithm is adopted for the multiple scene photos. A standard Web flow transmission method is adopted. A configuration file, material information and light source data information of the whole space environment and then different component models and secondary models in the space environment according to component critical level of the components from high to low are transmitted in sequence. Then data of an adjacent scene of the initial scene is transmitted. Finally, residual data is transmitted. By adopting the above method, waiting time for real time rendering is reduced distinctively and real time rendering efficiency and effect are improved.

Description

technical field [0001] The invention relates to the technical field of 3D scene rendering, in particular to a real-time interactive rendering method based on scene decoration. Background technique [0002] With the rapid development of computer technology and multimedia technology, image processing and display has crossed from the 2D era to the 3D era. 3D movies, virtual reality, 3D games, etc. are all widely used 3D technology in people's daily life environment. In the field of home decoration, people have also moved from traditional 2D renderings to 3D renderings. More and more decoration software and decoration companies have begun to apply 3D rendering technology to show users a more realistic post-decoration experience. . [0003] In these 3D applications, the technical realization method is mainly through the rendering server, relying on the mainstream rendering software to render the 3D model, and then combine the rendering effect with video, picture or multiple pic...
