HRESULT IRdD3DLayer::Clear

(

void

)

Clear all data in the Layer.

HRESULT IRdD3DLayer::GetID

(

[out] RtDWORD *

pVal

)

Return Renderer's ID for the Direct3D Layer. This is internal method of D3DView.

HRESULT IRdD3DLayer::SetID

(

[in] RtDWORD

pVal

)

Stores Renderer's ID for the Direct3D Layer. This is internal method of D3DView.

HRESULT IRdD3DLayer::GetScanningRootsCount

(

[out] RtDWORD *

pVal

)

Method returns the number of graph roots that the associated render target is required to scan for updates.

Parameters:

pVal

is filled with the root count.

HRESULT IRdD3DLayer::GetScanningRoot	(	[in] RtDWORD	dwIndex,
		[out] BSTR *	pVal,
		[out] DWORD *	dwRootType
	)

Method returns the scanning root at specified index.

Root type is combination of following values: D3DSR_VIEWROOT - 1 - This root is a viewroot - only subobjects are processed. D3DRS_OBJECT - 2 - This root is a plain watched object (i.e. camera, light). D3DRS_CAMERA - 4 - This root is a camera object.

Parameters:

	dwIndex	specifies the index of the root
	pVal	is filled with the root string
	dwRootType	is filled with the root type

HRESULT IRdD3DLayer::AddScanningRoot	(	[in] BSTR	pVal,
		[in] DWORD	dwRootType
	)

Method adds scanning root to the list (if not there already).

Root type is combination of following values: D3DSR_VIEWROOT - 1 - This root is a viewroot - only subobjects are processed. D3DRS_OBJECT - 2 - This root is a plain watched object (i.e. camera, light). D3DRS_CAMERA - 4 - This root is a camera object.

Parameters:

	pVal	specifies the root string
	dwRootType	specifies the root type

HRESULT IRdD3DLayer::AppendScanningRoots

(

[in] IRdD3DLayer *

pVal

)

Method adds scanning roots from other layer to current one.

Parameters:

pVal

specifies the layer whose roots to add.
