Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A method for controlling a real-time rendering engine comprising the steps of: defining in a first region of system memory, a block header comprising an instructions count field for storing the number of instructions within a block; an instruction identification field for defining the format of the corresponding instructions; a hardware version number field for identifying the supported hardware version level; and enable/bypass fields for programmably enabling or bypassing rendering functions; where the block header is to be processed before the corresponding instructions; and defining in a second region of said memory, flow-control instructions.
Claim 2
Independent Claim
94 words
A method for controlling a real-time rendering engine comprising the steps of: defining in a first region of system memory, a block header comprising an instructions count field for storing the number of instructions within a block; an instruction identification field for defining the format of the corresponding instructions; a hardware version number field for identifying the supported hardware version level; and enable/bypass fields for programmably enabling or bypassing rendering functions; where the block header is to be processed before the corresponding instructions; and defining in a second region of said memory, flow-control instructions.
Claim 3
Dependent Claim
31 words
The method of claim 1, further comprising the step of defining in the block header a vertex replace-mode field for controlling automatic generation of `strip` and `fan` forms of triangle chains.
Claim 4
Dependent Claim
14 words
The method of claim 1, wherein said flow-control instructions comprise time-deferred vertex-based draw lists.
Claim 5
Dependent Claim
23 words
The method of claim 1, wherein said flow-control instructions comprise `immediate` instructions for issuing commands to the rendering engine on a non-time-deferred basis.
Claim 6
Dependent Claim
63 words
A computer-readable memory device encoded with a block header for controlling a real-time rendering engine, comprising: an instructions count field for storing the number of instructions within a block; an instruction identification field for defining the format of the corresponding instructions; a hardware version number field for identifying the supported hardware version level; and enable/bypass fields for programmably enabling or bypassing rendering functions.
Claim 7
Dependent Claim
63 words
A computer-readable memory device encoded with a block header for controlling a real-time rendering engine, comprising: an instructions count field for storing the number of instructions within a block; an instruction identification field for defining the format of the corresponding instructions; a hardware version number field for identifying the supported hardware version level; and enable/bypass fields for programmably enabling or bypassing rendering functions.
Claim 8
Dependent Claim
14 words
The computer-readable memory device of claim 5, further comprising a list of flow-control instructions.
Claim 9
Dependent Claim
16 words
The computer-readable memory device of claim 5, wherein the flow-control instructions comprise time-deferred vertex-based draw lists.
Claim 10
Dependent Claim
25 words
The computer-readable memory device of claim 5, wherein said flow-control instructions comprise `immediate` instructions for issuing commands to the rendering engine on a non-time-deferred basis.
Claim 11
Dependent Claim
28 words
The computer-readable memory device of claim 5, wherein the block header comprises a vertex replace-mode field for controlling automatic generation of `strip` and `fan` forms of triangle chains.
Claim 12
Independent Claim
105 words
A system for controlling a real-time rendering engine comprising: a central processing unit (CPU); coupled to the CPU, a memory comprising a control program for defining in a first region of system memory, a block header comprising: an instructions count field for storing the number of instructions within a block; an instruction identification field for defining the format of the corresponding instructions; a hardware version number field for identifying the supported hardware version level; and enable/bypass fields for programmably enabling or bypassing rendering functions; coupled to the CPU, a memory comprising a control program for defining in a second region of system memory, flow-control instructions.
Claim 13
