Effect states are name value pairs in the form of an expression.

Effect Object State

This Effect Object Maps to
RASTERIZERSTATE A Rasterizer State state object.
DEPTHSTENCILSTATE A Depth and Stencil State state object.
BLENDSTATE A Blend State state object.
VERTEXSHADER A compiled vertex shader object.
PIXELSHADER A compiled pixel shader object.
GEOMETRYSHADER A compiled geometry shader object.
DS_STENCILREFAB_BLENDFACTORAB_SAMPLEMASK Members of D3DX11_PASS_DESC.

 

Defining and using state objects

State objects are declared in FX files in the following format. StateObjectType is one of the states listed above and MemberName is the name of any member that will have a non-default value.

StateObjectType ObjectName {
  MemberName = value;
  ...
  MemberName = value;
};

For example, to set up a blend state object with AlphaToCoverageEnable and BlendEnable[0] set to FALSE the following code would be used.

BlendState NoBlend {
  AlphaToCoverageEnable = FALSE;
  BlendEnable[0] = FALSE;
};

The state object is applied to a technique pass using one of the SetStateGroup functions described in Effect Technique Syntax (Direct3D 11). For example, to apply the BlendState object described above the following code would be used.

SetBlendState( NoBlend, float4( 0.0f, 0.0f, 0.0f, 0.0f ), 0xFFFFFFFF );
