Abstract

This paper presents an architecture for 3D virtual environment rendering on the Web applied to computers with limited capacity for graphics processing, which do not have a GPU for rendering the virtual environment. 3D rendering of the scene is done remotely, on demand, and employs 3D warping technique for generating views locally in the client. Thus, the client is able to render new views while waiting for data requested to the server or even when there are problems in the transmission or receiving delay. The proposed architecture allows the virtual environment rendering using residual images, which make the data transmission between client and server more efficient since less information is sent when compared to complete frames rendered from the 3D model. A method for taking advantage of the residual images received by clients is proposed and implemented, improving the quality of the resulting views instead of being discarded. Furthermore, an approach to reducing the quality degradation problem of the views locally rendered in the client is presented.
