IMAGE-BASED RENDERING SYSTEM FOR DYNAMIC OBJECTS IN A VIRTUAL ENVIRONMENT

摘要

The invention relates to a system for rendering a multiplicity of dynamic three-dimensional objects in a virtual environment, the system comprising a memory for storing a plurality of sample images representing the objects viewed from different angles, the system further comprising processing means configured for: for each object to be displayed, selecting a sample image from the memory based on the angle of viewing the object, wherein the pixels of the sample image include an alpha channel value for identifying a plurality of different regions of the image; mapping the sample image to a polygon representing the location of the object in the environment, including performing multi-pass rendering of the sample image, wherein each pass is for rendering differently coloured regions of the sample image identified by the alpha channel values.
