ID3DX11Effect interface
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
