Saving Pixel State With a StateBlock (Direct3D 9)

A state block can be used to capture only pixel state (see State Blocks Save and Restore State (Direct3D 9)). The following state is pixel state:

To capture pixel state with a state block, specify D3DSBT_PIXELSTATE when calling IDirect3DDevice9::CreateStateBlock.

Pixel 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 pixel state:

Pixel 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 pixel state:

Sampler States Default Value
D3DSAMP_ADDRESSU D3DTADDRESS_WRAP
D3DSAMP_ADDRESSV D3DTADDRESS_WRAP
D3DSAMP_ADDRESSW D3DTADDRESS_WRAP
D3DSAMP_BORDERCOLOR 0x00000000
D3DSAMP_MAGFILTER D3DTEXF_POINT
D3DSAMP_MINFILTER D3DTEXF_POINT
D3DSAMP_MIPFILTER D3DTEXF_NONE
D3DSAMP_MIPMAPLODBIAS 0
D3DSAMP_MAXMIPLEVEL 0
D3DSAMP_MAXANISOTROPY 1
D3DSAMP_SRGBTEXTURE 0
D3DSAMP_ELEMENTINDEX 0

 

Pixel Pipeline: Texture State

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

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

Texture States Default Value
D3DTSS_COLOROP D3DTOP_DISABLE
D3DTSS_COLORARG1 D3DTA_TEXTURE
D3DTSS_COLORARG2 D3DTA_CURRENT
