Saving Vertex States With a StateBlock

A state block can be used to capture only vertex state (see State Blocks Save and Restore State). The following state is vertex state:

Vertex render state (see Vertex Pipeline: Render State).
Vertex sampler state (see Vertex Pipeline: Sampler State).
Vertex texture state (see Vertex Pipeline: Texture State).
The NPatch mode segments from IDirect3DDevice9::SetNPatchMode.
Each light from IDirect3DDevice9::SetLight, as well as whether or not the light is enabled with IDirect3DDevice9::LightEnable.
The current vertex shader and each of the vertex shader constants.
For each vertex stream, store the divider value from IDirect3DDevice9::SetStreamSourceFreq.
The current vertex declaration.

To capture vertex state with a state block, specify D3DSBT_VERTEXSTATE when calling IDirect3DDevice9::CreateStateBlock.

Vertex Pipeline: Render State

Device render states affect the behavior of almost every part of the pipeline. Render states are set by calling IDirect3DDevice9::SetRenderState.

The following table includes all render states that set-up vertex state:

Vertex Pipeline: Sampler State

Sampler states control sampling related topics such as filtering, tiling, and texture coordinate address modes. Use IDirect3DDevice9::SetSamplerState to set up the sampler state (including the one used in the tessellator unit to sample displacement maps). The sampler states have been renamed with a "D3DSAMP_" prefix to enable compile time error detection when porting from DirectX 8.

The following table includes all sampler states that set-up vertex state:

Sampler States	Default Value
D3DSAMP_DMAPOFFSET	256

Vertex Pipeline: Texture State

Texture states control texture blending operations of the multi-texture blender. Use IDirect3DDevice9::SetTextureStageState to set-up texture states. Use IDirect3DDevice9::SetTexture to associate a texture with a sampler stage.

The following table includes all the texture states that set-up vertex state:

Texture States	Default Value
D3DTSS_TEXCOORDINDEX	0
D3DTSS_TEXTURETRANSFORMFLAGS	D3DTTFF_DISABLE

D3DTSS_TEXCOORDINDEX is a fixed function vertex processing state. If a programmable vertex shader is used, this state is ignored.
