Append (DirectX HLSL Stream-Output Object)
Append geometry-shader-output data to an existing stream.
Append( StreamDataType);
Parameters
| Item | Description |
|---|---|
| StreamDataType |
A data input description. This description must match the stream-object template parameter called DataType. |
Return Value
None
Example
This code snippet (from the CubeMapGS Sample) shows a partial example of appending triangle strip primitives to a stream-output object.
[maxvertexcount(18)]
void GS_CubeMap( triangle GS_CUBEMAP_IN input[3],
inout TriangleStream<PS_CUBEMAP_IN> CubeMapStream )
{
for( int f = 0; f < 6; ++f )
{
// Compute screen coordinates
PS_CUBEMAP_IN output;
output.RTIndex = f;
for( int v = 0; v < 3; v++ )
{
output.Pos = mul( input[v].Pos, g_mViewCM[f] );
output.Pos = mul( output.Pos, mProj );
output.Tex = input[v].Tex;
CubeMapStream.Append( output );
}
CubeMapStream.RestartStrip();
}
}
