Abstract
A method and apparatus for operating a computer graphics system to perform a conditional test on a node in a graphics data structure during the traversal of the graphics data structure by a structure walker. The graphics system is operated to manipulate data contained in a memory to define a value for an operand that is to be tested. The system accesses the operand from the memory. A structure walker performs a test on the value of the operand during traversal of the graphics data structure. Depending upon the result of the test, the structure walker traverses one of several paths in the graphics data structure to create a graphics display.
