RENDER TRANSFORM BASED SCROLLING AND PANNING FOR SMOOTH EFFECTS

摘要

An information display system is described herein that separates rendering of information from receiving that information so that the rendering portion can be quickly displayed to the user and the data can arrive as it is available to provide further detail. The rendering portion creates a hardware surface measured to fill the area to be consumed by the list box or other control. Independently, the information retrieval portion queries information from a server or other source and processes the information as it is received. The system can then perform a transformation on the previously created hardware surface to insert the information in the rendered control without re-laying out the entire control or recreating user interface elements. Moving a surface is a cheaper operation for a CPU and can easily be accelerated using a GPU.
