摘要:
A method for operating a computer graphics system to build custom nodes containing commands and data information that is stored in a data structure in the graphics subsystem. A host processor calls routines which build the custome nodes. A structure walker traverses the data structure and extracts the information from the data structure to pass it to the graphics subsystem for display. The use of custom nodes increases the flexibility of advanced graphics data structures bny allowing the creation of other data structures during execution of a first data structure.
