Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
43 words
A method for rendering, with a plurality of processors, a primitive having a plurality of spans comprising the steps of: assigning at least one span to each processor; each processor calculating endpoints within the primitive for each assigned span; and displaying the primitive.
Claim 2
Dependent Claim
18 words
The method of Claim 1 wherein the step of assigning includes interleaving the spans assigned to the processors.
Claim 3
Dependent Claim
24 words
The method of Claim 1 or 2 wherein the step of calculating includes calculating span endpoints as an increment from a previously calculated endpoint.
Claim 4
Dependent Claim
17 words
The method of Claim 3 further comprising a step of interpolating values for points between calculated endpoints.
Claim 5
Dependent Claim
21 words
The method of Claim 1, 2, 3 or 4 further comprising a step of updating a frame buffer with interpolated values.
Claim 6
Independent Claim
41 words
An apparatus for rendering a primitive having a plurality of spans comprising: a plurality of processors; means for assigning at least one span to each processor; and each processor including means for calculating endpoints within the primitive for each assigned span.
Claim 7
Dependent Claim
20 words
The apparatus of Claim 6 wherein the means for assigning includes means for interleaving the spans assigned to the processors.
Claim 8
Dependent Claim
26 words
The apparatus of Claim 6 or 7 wherein the means for calculating includes means for calculating span endpoints as an increment from a previously calculated endpoint.
Claim 9
Dependent Claim
16 words
The apparatus of Claim 8 further comprising means for interpolating values for points between calculated endpoints.
Claim 10
Dependent Claim
20 words
The apparatus of Claim 6, 7, 8 or 9 further comprising means for updating a frame buffer with interpolated values.
Claim 11
Dependent Claim
66 words
The apparatus of Claim 6, 7, 8, 9 or 10 wherein the apparatus is a data processing system comprising: a processor for processing data; a memory for storing data to be processed; and an adapter coupled to the processor and memory for performing graphics functions, the adapter including: said plurality of graphics processors; said means for assigning; and each graphics processor including said means for calculating.
