 // Init device first
 // ... 
 
 Sire::Init(Sire::SIRE_RENDERER_DX11, pSwapChain); // <- pass dxgi swapchain as argument
 
 while (...) {
   /// Clear render target view.
   
   Sire::SetProjectionMode(Sire::SIRE_PROJ_ORTHOGRAPHIC);
   Sire::SetTexture(nullptr, nullptr);
   
   Sire::Begin(Sire::SIRE_TRIANGLE);    
   Sire::SetVertex2f(0.0f, 0.5f);
   Sire::SetVertex2f(0.45f, -0.5f);
   Sire::SetVertex2f(-0.45f, -0.5f);
   Sire::End();
       
   /// Present.
 }
 
 Sire::Shutdown();
 
 // Shutdown device after
 // ...
}
