ID3D11Device::CreateGeometryShader Method

Create a geometry shader.

Syntax

HRESULT CreateGeometryShader(
  [in]   const void *pShaderBytecode,
  [in]   SIZE_T BytecodeLength,
  [in]   ID3D11ClassLinkage *pClassLinkage,
  [out]  ID3D11GeometryShader **ppGeometryShader
);

Parameter

• pShaderBytecode [in]
  Typ: const void*

  A pointer to the compiled shader.

• BytecodeLength [in]
  Typ: SIZE_T

  Size of the compiled geometry shader.

• pClassLinkage [in]
  Typ: ID3D11ClassLinkage*

  A pointer to a class linkage interface (see ID3D11ClassLinkage); the value can be NULL.

• ppGeometryShader [out]
  Typ: ID3D11GeometryShader**

  Address of a pointer to a ID3D11GeometryShader interface. If this is NULL, all other parameters will be validated, and if all parameters pass validation this API will return S_FALSE instead of S_OK.

Rückgabewert

Typ: HRESULT

This method returns one of the following Direct3D 11 Return Codes.

Hinweise

Once created, the shader can be set to the device by calling ID3D11DeviceContext::GSSetShader.

Beispiele

Usage Example

ID3D11GeometryShader*       g_pGeometryShader11 = NULL;
ID3DBlob* pGeometryShaderBuffer = NULL;
ID3DBlob * errorbuffer = NULL;

D3DX11CompileFromFile( str, NULL, NULL, "GS", "gs_4_0", dwShaderFlags, 0, NULL,
                                         &pGeometryShaderBuffer, &errorbuffer, NULL );

pd3dDevice->CreateGeometryShader( pGeometryShaderBuffer->GetBufferPointer(),
               pGeometryShaderBuffer->GetBufferSize(), NULL, &g_pGeometryShader11 );
