- Description
The TDx_3DDevice::GetInfo() method will retrieve Direct3D or device driver rendering information.
This method can reveal driver specific types and structures not documented in Dx7.
Use this method on debug Dx7, as attempts to use it on retail Dx7 will cause the method succeed but return with S_FALSE.
Execution is synchronous and can impact performance, so do not call it between calls to TDx_3DDevice::BeginScene() and TDx_3DDevice::EndScene().
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
- Parameters
DevInfoID
The DevInfoID parameter indicates what type of information to retrieve.
The described effect applies when the flag is set.
-
D3DDEVINFOID_D3DTEXTUREMANAGER
DevInfoStruct references a TD3DDevInfo_TextureManager component for holding Direct3D texture management information.
D3DDEVINFOID_TEXTUREMANAGER
DevInfoStruct references a TD3DDevInfo_TextureManager component for holding device driver texture management information.
If the driver performs no texture management, Direct3D texture management information will be retrieved instead.
D3DDEVINFOID_TEXTURING
DevInfoStruct references a TD3DDevInfo_Texturing component for holding the applications texturing activity.
The DevInfoStruct parameter will reference the specified device information if this method returns successfully.
This can be a TD3DDevInfo_Texturing or a TD3DDevInfo_TextureManager component, as specified by the DevInfoID parameter.
Size
The Size parameter defines the size, in bytes, of the component referenced by the DevInfoStruct parameter.
