Hi,

Im drawing everything in my scene using effects (ID3DXEffect) and ID3DXMesh::DrawSubset.

There are only one type of object (MeasurementLines) that Im rendering using IDirect3DDevice9::DrawPrimitiveUP. Im drawing these MeasurementLine objects after Im rendering all the others, but I cant seem to set the IDirect3DDevice9::SetTransform and the device does not draw these lines the color that I set them when I create their FVF.

Im probably missing something fundamental, but dont know what it is.


D3DVertexColor l_aVertexPositionData[2];

l_aVertexPositionData[0].position.x = this->m_pStartPoint->GetWorldTransform()->GetPosition().x;
l_aVertexPositionData[0].position.y = this->m_pStartPoint->GetWorldTransform()->GetPosition().y;
l_aVertexPositionData[0].position.z = this->m_pStartPoint->GetWorldTransform()->GetPosition().z;

l_aVertexPositionData[1].position.x = this->m_pEndPoint->GetWorldTransform()->GetPosition().x;
l_aVertexPositionData[1].position.y = this->m_pEndPoint->GetWorldTransform()->GetPosition().y;
l_aVertexPositionData[1].position.z = this->m_pEndPoint->GetWorldTransform()->GetPosition().z;

l_aVertexPositionData[0].color = 0xff000000;

l_aVertexPositionData[1].color = 0xff000000;

D3DXMATRIX l_d3dmIdentity;

D3DXMatrixIdentity( &l_d3dmIdentity );

HRESULT hr;

ENGINEMANAGER->GetGraphicsDevice()->SetFVF( D3DFVF_XYZ | D3DFVF_DIFFUSE );

hr = ENGINEMANAGER->GetGraphicsDevice()->SetTransform( D3DTS_WORLD, &l_d3dmIdentity );

hr = ENGINEMANAGER->GetGraphicsDevice()->SetTransform( D3DTS_VIEW, &D3DCAMERAMANAGER->GetActiveCamera()->GetProjectionMatrix() );

hr = ENGINEMANAGER->GetGraphicsDevice()->SetTransform( D3DTS_PROJECTION, &D3DCAMERAMANAGER->GetActiveCamera()->GetViewMatrix() );

ENGINEMANAGER->GetGraphicsDevice()->SetRenderState( D3DRS_ZENABLE, D3DZB_FALSE );

hr = ENGINEMANAGER->GetGraphicsDevice()->DrawPrimitiveUP( D3DPT_LINESTRIP, 1, (void *)l_aVertexPositionData, sizeof( D3DVertexColor ) );


So in summary, it draws the line primitive, but does not take the color I specify or the Word transform into account. How do I fix this?
