  • Graphics application programming interface avoiding repetitive transfer of texture mapping data
    Patent number: 6046747
    Abstract: A computer graphics system includes a host computer, including a graphics application program and an application programming interface, and graphics hardware. The application programming interface creates a display list for receiving and storing user-specified commands and stores each user-specified texture download command in a texture image list. When a texture processing command is received and the corresponding texture map is optimizable, the texture image list is stored in a texture object, the texture object is marked as not downloaded and a bind texture call is inserted in the display list. The bind texture call contains a reference to the texture object.
