We present a framework for optimizing the streaming of large 3D applications to allow an instant interaction independently from network bandwidth or available processing power of the rendering unit. The instantaneous display of imperfect content that gets continuously refined is state of the art for many application areas on the web, why we propose to utilize this idea for interactive 3D web applications. To achieve this, two new approaches were chosen. In addition to a progressive transmission of geometry and texture data, we firstly propose an overall rating function to control the priorities between different media transmission blocks. Secondly, we use a similarity metric to use already loaded scene parts as a replacement of parts with lower priority. Our approach utilizes a client-server architecture to collect, convert, control, and transmit the scene data at runtime to allow an instant distribution of adapted data, while also reducing the CPU load and network traffic.
