摘要：A graphics processing pipeline comprises a tessellation stage that is configuredto tessellate a patch into tessellation primitives. When tessellating the patch, thetessellation stage generates tessellation vertex coordinate pairs that define within aparameter space the locations of vertices of the tessellation primitives for the patch. The

tessellation vertex coordinate pairs are initially represented using a first binaryrepresentation and are then encoded into a more convenient second binaryrepresentation, but without any loss of resolution in the data. The step of encodingcomprises mapping at least one of the tessellation vertex coordinate pairs to a mappedcoordinate pair that can be represented using the second binary representation, whereinthe mapped coordinate pair defines a location within an area of the parameter space thatwould otherwise be unused, invalid and/or unreachable for the vertices of thetessellation primitives for the patch.
