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 81 words
A graphics system command stream for use in a graphics system having a buffer, the graphics system command stream being operable upon execution to clear a buffer, comprising: a stream command 0×614F followed by a pad, an alpha value and a red value; a stream command 0×6150 followed by a pad, a green value and a blue value; and a stream command 0×6151 followed by a 24-bit z value, wherein upon execution of the graphics command stream the buffer is cleared.
Claim 2
Dependent Claim 81 words
A graphics system command stream for use in a graphics system having a buffer, the graphics system command stream being operable upon execution to clear a buffer, comprising: a stream command 0×614F followed by a pad, an alpha value and a red value; a stream command 0×6150 followed by a pad, a green value and a blue value; and a stream command 0×6151 followed by a 24-bit z value, wherein upon execution of the graphics command stream the buffer is cleared.
Claim 3
Dependent Claim 64 words
A computer readable storage medium encoded with executable instructions for clearing a buffer comprising: a stream command 0×614F followed by a pad, an alpha value and a red value; a stream command 0×6150 followed by a pad, a green value and a blue value; and a stream command 0×6151 followed by a 24-bit z value, wherein execution of the encoded instructions clears the buffer.
Claim 4
Dependent Claim 64 words
A computer readable storage medium encoded with executable instructions for clearing a buffer comprising: a stream command 0×614F followed by a pad, an alpha value and a red value; a stream command 0×6150 followed by a pad, a green value and a blue value; and a stream command 0×6151 followed by a 24-bit z value, wherein execution of the encoded instructions clears the buffer.
Claim 5
Dependent Claim 62 words
A graphics command stream decoder comprising: a first decoding section decoding a stream command 0×614F followed by a pad, an alpha value and a red value; a second decoding section decoding a stream command 0×6150 followed by a pad, a green value and a blue value; and a third decoding section decoding a stream command 0×6151 followed by a 24-bit z value.
Claim 6
Dependent Claim 62 words
A graphics command stream decoder comprising: a first decoding section decoding a stream command 0×614F followed by a pad, an alpha value and a red value; a second decoding section decoding a stream command 0×6150 followed by a pad, a green value and a blue value; and a third decoding section decoding a stream command 0×6151 followed by a 24-bit z value.
Claim 7
Independent Claim 74 words
A method of clearing a buffer in a graphics system using a graphics command stream, the method comprising: generating a stream command 0×614F followed by a pad, an alpha value and a red value; generating a stream command 0×6150 followed by a pad, a green value and a blue value; and generating a stream command 0×6151 followed by a 24-bit z value, wherein upon execution of the graphics command stream the buffer is cleared.
Claim 8
Independent Claim 74 words
A method of clearing a buffer in a graphics system using a graphics command stream, the method comprising: generating a stream command 0×614F followed by a pad, an alpha value and a red value; generating a stream command 0×6150 followed by a pad, a green value and a blue value; and generating a stream command 0×6151 followed by a 24-bit z value, wherein upon execution of the graphics command stream the buffer is cleared.
