Transmission Method of the Rendered Image based on Cube Environment Mapping

Abstract

The communication between server and browser is the basic problem of remote rendering under B / S architecture. This paper first describes the difficulties of rendered image transmission, then analyzes the model characteristics in virtual reality environment, and summarizes the user action law based on the model characteristics. Because there are a large number of view rotation operations and view movement operations, and the view rotation operations are more frequent than the view movement operations, a rendered image transmission method based on cube environment mapping is proposed for view rotation; When the user rotates the view angle, it does not rely on the server rendering, but directly re renders the picture under the current view angle from the existing data. Compared with the direct transmission of 3D scene data and direct rendering results, the method proposed in this paper has nothing to do with the complexity of 3D scene and the computing power of the terminal. It can realize remote rendering with zero bandwidth pressure.
