ProcessTriTessFactorsAvg function
Generates the corrected tessellation factors for a tri patch.
Syntax
void ProcessTriTessFactorsAvg(
in float3 RawEdgeFactors,
in float InsideScale,
out float3 RoundedEdgeTessFactors,
out float RoundedInsideTessFactor,
out float UnroundedInsideTessFactor
);
Parameters
-
RawEdgeFactors [in]
-
Type: float3
The edge tessellation factors, passed into the tessellator stage.
-
InsideScale [in]
-
Type: float
The scale factor applied to the UV tessellation factors computed by the tessellation stage. The allowable range for InsideScale is 0.0 to 1.0.
-
RoundedEdgeTessFactors [out]
-
Type: float3
The rounded edge-tessellation factors calculated by the tessellator stage.
-
RoundedInsideTessFactor [out]
-
Type: float
The tessellation factors calculated by the tessellator stage, and rounded.
-
UnroundedInsideTessFactor [out]
-
Type: float
The original, unrounded, UV tessellation factors computed by the tessellation stage.
Return value
This function does not return a value.
Remarks
Generates the corrected tessellation factors for a tri patch, computing the inside tessellation factor as the average of the edge tessellation factors, which is then scaled by InsideScale. The result is then rounded based on the partitioning mode, but the unrounded results are available using the UnroundedInsideTessFactor parameter.
