Multimedia content delivery system

摘要

A multimedia content delivery system includes a server apparatus (100) for delivering graphical information across a network (30) to a client device (200).An environment engine (150) controls a virtual environment responsive to user commands. An object transformation unit (400, 405) transforms original object data (310) relating to a plurality of objects into compressed object data (350). A data management unit (120) transmits the compressed object data to the client device (200). The compressed object data (350) is decompressed and rendered by the client device (200) to output images to represent the virtual environment on a visual display device. Server-side and client side I/O handler units(130, 230) provide the user commands from the client device (200).The compressed object data (360) may comprise coefficients of a solution to a partial differential equation. Methods and apparatus are described relating to polygon-based object geometry (510) and pixel-based image files (600) which are transformed and regenerated using coefficients (540, 606) of a solution to a partial differential equation.
