  • Texture data compression and rendering in 3D computer graphics
    Patent number: 7463269
    Abstract: View-dependent texture images and view-independent texture data for a 3D computer model are processed to compress each view-dependent texture image by subtracting the view-dependent data and view-independent data in a common 2D image space to generate a difference image, and compression encoding the difference image. The difference images, 3D computer model and view-independent texture data are transmitted to a second apparatus, where the difference data and view-independent texture data are recombined in a common 2D image space as part of the processing to render an image.
