ID3DX11Effect interface

  • Article

An ID3DX11Effect interface manages a set of state objects, resources, and shaders for implementing a rendering effect.

Members

The ID3DX11Effect interface inherits from the IUnknown interface. ID3DX11Effect also has these types of members:

Methods

The ID3DX11Effect interface has these methods.

Method Description
CloneEffect Creates a copy of an effect interface.
GetClassLinkage Gets a class linkage interface.
GetConstantBufferByIndex Get a constant buffer by index.
GetConstantBufferByName Get a constant buffer by name.
GetDesc Get an effect description.
GetDevice Get the device that created the effect.
GetGroupByIndex Gets an effect group by index.
GetGroupByName Gets an effect group by name.
GetTechniqueByIndex Get a technique by index.
GetTechniqueByName Get a technique by name.
GetVariableByIndex Get a variable by index.
GetVariableByName Get a variable by name.
GetVariableBySemantic Get a variable by semantic.
IsOptimized Test an effect to see if the reflection metadata has been removed from memory.
IsValid Test an effect to see if it contains valid syntax.
Optimize Minimize the amount of memory required for an effect.

Remarks

An effect is created by calling D3DX11CreateEffectFromMemory.

The effect system groups the information required for rendering into an effect which contains: state objects for assigning state changes in groups, resources for supplying input data and storing output data, and programs that control how the rendering is done called shaders.

Note

The DirectX SDK does not supply any compiled binaries for effects. You must use Effects 11 source to build your effects-type application. For more information about using Effects 11 source, see Differences Between Effects 10 and Effects 11.

Note

If you call QueryInterface on an ID3DX11Effect object to retrieve the IUnknown interface, QueryInterface returns E_NOINTERFACE. To work around this issue, use the following code:

    IUnknown* pIUnknown = (IUnknown*)pEffect;>     pIUnknown->AddRef();

Requirements

Header
D3dx11effect.h
Library
