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 85 words
A graphics system command stream for use in a graphics system, the command stream being operable upon execution to set a vertex descriptor, the command stream comprising: a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes, wherein upon execution of the command stream the vertex descriptor is set.
Claim 2
Dependent Claim 85 words
A graphics system command stream for use in a graphics system, the command stream being operable upon execution to set a vertex descriptor, the command stream comprising: a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes, wherein upon execution of the command stream the vertex descriptor is set.
Claim 3
Dependent Claim 71 words
A computer readable storage medium encoded with executable instructions for setting a vertex descriptor comprising: a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes, wherein execution of the encoded instructions sets the vertex descriptor.
Claim 4
Dependent Claim 71 words
A computer readable storage medium encoded with executable instructions for setting a vertex descriptor comprising: a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes, wherein execution of the encoded instructions sets the vertex descriptor.
Claim 5
Dependent Claim 62 words
A graphics command stream decoder comprising: a first decoding section decoding a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and a second decoding section decoding a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes.
Claim 6
Dependent Claim 62 words
A graphics command stream decoder comprising: a first decoding section decoding a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and a second decoding section decoding a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes.
Claim 7
Independent Claim 76 words
A method of setting a vertex descriptor using a graphics command stream, the method comprising: generating a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and generating a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes, wherein upon execution of the graphics command stream the vertex descriptor is set.
Claim 8
Independent Claim 76 words
A method of setting a vertex descriptor using a graphics command stream, the method comprising: generating a stream command 0x0850 followed by a 32-bit value including seventeen bits defining attribute indexing information for up to twelve attributes, and generating a further stream command 0x0860 followed by a 32-bit value including sixteen bits encoding attribute indexing information for up to an additional eight attributes, wherein upon execution of the graphics command stream the vertex descriptor is set.
