This C++ Function is found inside of [[CAdditionalVertexStreamManager]].

It sets an additional vertex stream.

It can be found in '''Client/Client Core/Sources/CAdditionalVertexStreamManager.cpp''' in Visual Studio.

==Required Arguments==
*'''state:''' To be defined.

==Code==
void CAdditionalVertexStreamManager::SetAdditionalVertexStream ( SCurrentStateInfo& state )
{
HRESULT hr;

// Get matching custom N vbuffer for std PT vbuffer
SAdditionalStreamInfo* pAdditionalInfo = GetAdditionalStreamInfo ( state.stream1.pStreamData );
if ( !pAdditionalInfo )
pAdditionalInfo = CreateAdditionalStreamInfo ( state );

uint StridePT = 20;
uint StrideN = 12;

// Calc area we are going to use
uint viMinBased = state.args.MinVertexIndex + state.args.BaseVertexIndex;
uint viMaxBased = state.args.MinVertexIndex + state.args.NumVertices + state.args.BaseVertexIndex;

uint ReadOffsetStart = viMinBased * StridePT + state.stream1.OffsetInBytes;
uint ReadOffsetSize = ( viMaxBased - viMinBased ) * StridePT;

uint OffsetInBytesN = ConvertPTSize ( state.stream1.OffsetInBytes );
uint WriteOffsetStart = viMinBased * StrideN + OffsetInBytesN;
uint WriteOffsetSize = ( viMaxBased - viMinBased ) * StrideN;

assert ( WriteOffsetStart == ConvertPTSize ( ReadOffsetStart ) );
assert ( WriteOffsetSize == ConvertPTSize ( ReadOffsetSize ) );

// See if area VB area needs updating
if ( !pAdditionalInfo->ConvertedRanges.IsRangeSet ( WriteOffsetStart, WriteOffsetSize ) )
{
// Update VB area
UpdateAdditionalStreamContent ( state, pAdditionalInfo, ReadOffsetStart, ReadOffsetSize, WriteOffsetStart, WriteOffsetSize );
pAdditionalInfo->ConvertedRanges.SetRange ( WriteOffsetStart, WriteOffsetSize );
}

// Save old declaration
hr = m_pDevice->GetVertexDeclaration ( &m_pOldVertexDeclaration );

// Set declaration
hr = g_pProxyDevice->SetVertexDeclaration ( pAdditionalInfo->pVertexDeclaration );

// Set additional stream
uint OffsetInBytes = ConvertPTSize ( state.stream1.OffsetInBytes );
hr = m_pDevice->SetStreamSource ( 2, pAdditionalInfo->pStreamData, OffsetInBytes, pAdditionalInfo->Stride );
}
