摘要： A graphics system configured to apply multiple layers of texture information to primitives. The graphics system receives parameters defining a primitive and performs a size test on the primitive. If the size test cannot guarantee that a fragment size of the primitive is less than or equal to a fragment capacity of a texture accumulation buffer, the primitive is divided into subprimitives, and the graphics system applies the multiple layers of texture to fragments which intersect the primitive. The graphics system switches from a current layer to the layer next when it has applied textures corresponding to the current layer to all the fragments intersecting the primitive. The graphics system stores color values associated with the primitive fragments in the texture accumulation buffer between the application of successive texture layers.

摘要： A data processor architecture wherein the processors recognize two basic types of objects, an object being a representation of related information maintained in a contiguously-addresed set of memory locations. The first type of object contains ordinary data, such as characters, integers, reals, etc. The second type of object contains a list of access descriptors. Each access descriptor provides information for locating and defining the extent of access to an object associated with that access descriptor. The processors recognize complex objects that are combinations of objects of the basic types. One such complex object (a context) defines an environment for execution of objects accessible to a given instance of a procedural operation. The dispatching of tasks to the processors is accomplished by hardware-controlled queuing mechanisms (dispatching-port objects) which allow multiple sets of processors to serve multiple, but independent sets of tasks. Communication between asynchronous tasks or processes is accomplished by related hardware-controlled queuing mechanisms (buffered-port objects) which allow messages to move between internal processes or input/output processes without the need for interrupts. A mechanism is provided which allows the processors to communicate with each other. This mechanism is used to reawaken an idle processor to alert the processor to the fact that a ready-to-run process at a dispatching port needs execution.
