IDirect3DDevice9::CreateVertexShader Method

Creates a vertex shader.

Syntax

HRESULT CreateVertexShader(      

    const DWORD *pFunction,
    IDirect3DVertexShader9** ppShader
);

Parameters

pFunction
[in] Pointer to the vertex shader function token array. This parameter defines the operations to apply to each vertex.
ppShader
[out, retval] Pointer to the returned vertex shader interface. See IDirect3DVertexShader9.

Return Value

If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be one of the following values.
D3DERR_INVALIDCALL The method call is invalid. For example, a method's parameter may have an invalid value.
D3DERR_OUTOFVIDEOMEMORY Microsoft?Direct3D?does not have enough display memory to perform the operation.
E_OUTOFMEMORY Direct3D could not allocate sufficient memory to complete the call.

Remarks

When a device is created, IDirect3D9::CreateDevice uses the behavior flag to determine whether to process vertices in hardware or software. There are three possibilities.
Process vertices in hardware by setting D3DCREATE_HARDWARE_VERTEXPROCESSING.
Process vertices in software by setting D3DCREATE_SOFTWARE_VERTEXPROCESSING.
Process vertices in either hardware or software by setting D3DCREATE_MIXED_VERTEXPROCESSING.
Mixed-mode devices might need to switch between software and hardware processing after the device is created. In this case, use IDirect3DDevice9::SetSoftwareVertexProcessing.

D3DERR_INVALIDCALL	The method call is invalid. For example, a method's parameter may have an invalid value.
D3DERR_OUTOFVIDEOMEMORY	Microsoft?Direct3D?does not have enough display memory to perform the operation.
E_OUTOFMEMORY	Direct3D could not allocate sufficient memory to complete the call.
