ID3DX11EffectVariable::AsMatrix method

Get a matrix variable.

Syntax

ID3DX11EffectMatrixVariable* AsMatrix();

Parameters

This method has no parameters.

Return value

Type: ID3DX11EffectMatrixVariable*

A pointer to a matrix variable. See ID3DX11EffectMatrixVariable.

Remarks

AsMatrix returns a version of the effect variable that has been specialized to a matrix variable. Similar to a cast, this specialization will return an invalid object if the effect variable does not contain matrix data.

Applications can test the returned object for validity by calling IsValid.

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.

Requirements

Requirement	Value
Header	D3dx11effect.h
Library	N/A (An Effects 11 library is available online as shared source.)
