Abstract

Abstract An interface for a graphics system includes simple yet powerful constructs that are easy for an application programmer to use and learn. Features include a unique vertex representation allowing the graphics pipeline to retain vertex state information and to mix indexed and direct vertex values and attributes; a projection matrix value set command; a display list call object command; and an embedded frame buffer clear/set command.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 92 words
A graphics system command stream for use in a graphics system to set an array, the command stream comprising: an array base load register command comprising 0x08Ax, where the second-mentioned “x” after “A” encodes an attribute indicator, a 32-bit including a 26-bit address, a stream command 0x08Bx, where the second-mentioned “x” after “B” encodes an attribute indicator, and a succeeding 32-bit value including eight bits indicating a stride for an array, wherein upon executing of the command stream an array base and an array stride register are set for a vertex array.
Claim 2
Dependent Claim 92 words
A graphics system command stream for use in a graphics system to set an array, the command stream comprising: an array base load register command comprising 0x08Ax, where the second-mentioned “x” after “A” encodes an attribute indicator, a 32-bit including a 26-bit address, a stream command 0x08Bx, where the second-mentioned “x” after “B” encodes an attribute indicator, and a succeeding 32-bit value including eight bits indicating a stride for an array, wherein upon executing of the command stream an array base and an array stride register are set for a vertex array.
Claim 3
Dependent Claim 90 words
A computer readable storage medium encoded with executable instructions for setting an array, comprising: an array base load register comprising 0x08Ax, where the second-mentioned “x” after “A” encodes an attribute indicator, and a 32-bit value including a 26-bit address, a stream command 0x08Bx, where the second-mentioned “x” after “B” encodes an attribute indicator, and a succeeding 32 -bit value including eight bits indicating a stride for an array, wherein upon execution of the command stream an array base register and an array stride register are set for a vertex array.
Claim 4
Dependent Claim 90 words
A computer readable storage medium encoded with executable instructions for setting an array, comprising: an array base load register comprising 0x08Ax, where the second-mentioned “x” after “A” encodes an attribute indicator, and a 32-bit value including a 26-bit address, a stream command 0x08Bx, where the second-mentioned “x” after “B” encodes an attribute indicator, and a succeeding 32 -bit value including eight bits indicating a stride for an array, wherein upon execution of the command stream an array base register and an array stride register are set for a vertex array.
Claim 5
Dependent Claim 76 words
A graphics command stream decoder comprising: a first decoding section decoding an array base load register command comprising 0x08Ax, where the second-mentioned x encodes an attribute indicator, and a second decoding section decoding a 32-bit value including a 26-bit address, a third decoding section decoding a stream command 0x08Bx, where the second-mentioned x encodes an attribute indicator, and a fourth decoding section decoding a succeeding 32-bit value including eight bits indicating a stride for an array.
Claim 6
Dependent Claim 76 words
A graphics command stream decoder comprising: a first decoding section decoding an array base load register command comprising 0x08Ax, where the second-mentioned x encodes an attribute indicator, and a second decoding section decoding a 32-bit value including a 26-bit address, a third decoding section decoding a stream command 0x08Bx, where the second-mentioned x encodes an attribute indicator, and a fourth decoding section decoding a succeeding 32-bit value including eight bits indicating a stride for an array.
Claim 7
Independent Claim 91 words
A method of setting an array in a graphics system using a graphics command stream comprising: generating an array base load register comprising 0x08Ax, where the second-mentioned x encodes an attribute indicator, and generating a 32-bit value including a 26-bit address, generating a stream command 0x08Bx, where the second-mentioned x encodes an attribute indicator, and generating a succeeding 32-bit value including eight bits indicating a stride for an array, wherein upon execution of the command stream an array base register and an array stride register are set for a vertex array.
Claim 8
Independent Claim 91 words
A method of setting an array in a graphics system using a graphics command stream comprising: generating an array base load register comprising 0x08Ax, where the second-mentioned x encodes an attribute indicator, and generating a 32-bit value including a 26-bit address, generating a stream command 0x08Bx, where the second-mentioned x encodes an attribute indicator, and generating a succeeding 32-bit value including eight bits indicating a stride for an array, wherein upon execution of the command stream an array base register and an array stride register are set for a vertex array.
