ID3D10Effect interface

An ID3D10Effect interface manages a set of state objects, resources, and shaders for implementing a rendering effect.


The ID3D10Effect interface has these methods.

Method Description
ID3D10Effect::GetConstantBufferByIndex Get a constant buffer by index.
ID3D10Effect::GetConstantBufferByName Get a constant buffer by name.
ID3D10Effect::GetDesc Get an effect description.
ID3D10Effect::GetDevice Get the device that created the effect.
ID3D10Effect::GetTechniqueByIndex Get a technique by index.
ID3D10Effect::GetTechniqueByName Get a technique by name.
ID3D10Effect::GetVariableByIndex Get a variable by index.
ID3D10Effect::GetVariableByName Get a variable by name.
ID3D10Effect::GetVariableBySemantic Get a variable by semantic.
ID3D10Effect::IsOptimized Test an effect to see if the reflection metadata has been removed from memory.
ID3D10Effect::IsPool Test an effect to see if it is part of a memory pool.
ID3D10Effect::IsValid Test an effect to see if it contains valid syntax.
ID3D10Effect::Optimize Minimize the amount of memory required for an effect.


An effect is created by calling D3D10CreateEffectFromMemory.

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. For more information, see Effects (Direct3D 10).


If you call QueryInterface on an ID3D10Effect object to retrieve the IUnknown interface, QueryInterface returns E_NOINTERFACE. To work around this issue, use the following code:

IUnknown* pIUnknown = (IUnknown*)pEffect;
