Saving All Device States with a StateBlock

A state block can be used to capture all device states (see State Blocks Save and Restore State). The following state elements are included in the device state:

• Vertex state (see Saving Vertex States With a StateBlock).
• Pixel state (see Saving Pixel State With a StateBlock).
• Each texture assigned to a sampler.
• Each vertex texture.
• Each displacement map texture.
• The current texture palette.
• For each vertex stream: a pointer to the vertex buffer, each argument from IDirect3DDevice9::SetStreamSource, and the divider (if any) from IDirect3DDevice9::SetStreamSourceFreq.
• A pointer to the index buffer.
• The viewport.
• The scissors rectangle.
• The world, view, and projection matrices.
• The texture transforms.
• The clipping planes (if any).
• The current material.

To capture all device states with a state block, specify D3DSBT_ALL when calling IDirect3DDevice9::CreateStateBlock.
