Save State of a Direct3D Device

Question

State should include at least the following:

• All settings set via SetStreamResource()
• Indices

I have a class whose Draw() function will call SetStreamResource, set Indices and eventually call DrawIndexedPrimitive(). I would like to restore the device state before Draw() returns.

I am looking for something along the lines of GDI's SaveDC()/RestoreDC().

Answer 1

Looks like these will do it:

Microsoft::DirectX::Direct3D::Device::BeginStateBlock
Microsoft::DirectX::Direct3D::Device::EndStateBlock

Answer 2

State blocks are the mechanism provided by the API to save and restore chunks of device state. I cover the details of state blocks in Chapter 3. Direct3D Devices from my book The Direct3D Graphics Pipeline. You can download the PDF for that chapter from the link above.
