Process2DQuadTessFactorsMax function

Generates the corrected tessellation factors for a quad patch.

Syntax

void Process2DQuadTessFactorsMax(
  in   float4 RawEdgeFactors,
  in   float2 InsideScale,
  out  float4 RoundedEdgeTessFactors,
  out  float2 RoundedInsideTessFactors,
  out  float2 UnroundedInsideTessFactors
);

Parameters

RawEdgeFactors [in]

Type: float4

The edge tessellation factors, passed into the tessellator stage.

InsideScale [in]

Type: float2

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: float4

The rounded edge-tessellation factors calculated by the tessellator stage.

RoundedInsideTessFactors [out]

Type: float2

The rounded tessellation factors calculated by the tessellator stage for inside edges.

UnroundedInsideTessFactors [out]

Type: float2

The tessellation factors calculated by the tessellator stage for inside edges.

Return value

This function does not return a value.

Remarks

Generates the corrected tessellation factors for a quad patch, computing the inside tessellation factors as the maximum of the edge tessellation factors. The U and V inside tessellation factors are computed independently using the maximums of opposing sides of the domain, then are scaled by InsideScale. The result is then rounded based on the partitioning mode, but the unrounded results are available using the UnroundedInsideTessFactors parameter.
