Detailed Description

Get GPUs VRAM information using DirectX.

vtkDirectXGPUInfoList implements Probe() method of vtkGPUInfoList through the DirectX API. As recommended by Microsoft, the WMI interface is used for Windows XP and the DXGI interface is used for Windows Vista and later. (see documentation of VideoMemory sample of the DirectX SDK) ref: http://msdn.microsoft.com/en-us/library/ee419018(v=VS.85)

Member Function Documentation

static vtkDirectXGPUInfoList* vtkDirectXGPUInfoList::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkGPUInfoList.

static int vtkDirectXGPUInfoList::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGPUInfoList.

virtual int vtkDirectXGPUInfoList::IsA

(

const char *

name

)

[virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGPUInfoList.

static vtkDirectXGPUInfoList* vtkDirectXGPUInfoList::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkGPUInfoList.

virtual vtkObjectBase* vtkDirectXGPUInfoList::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkGPUInfoList.

vtkDirectXGPUInfoList* vtkDirectXGPUInfoList::NewInstance

(

)

const

Reimplemented from vtkGPUInfoList.

void vtkDirectXGPUInfoList::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		[virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkGPUInfoList.

virtual void vtkDirectXGPUInfoList::Probe

(

)

[virtual]

Build the list of vtkInfoGPU if not done yet.

Postcondition:

probed: IsProbed()

Implements vtkGPUInfoList.

bool vtkDirectXGPUInfoList::ProbeInfoWithDXGI	(	HMONITOR	m,
		vtkGPUInfo *	info
	)		[protected]

Probe the GPUs with the DXGI api (Windows Vista or later). It returns true if it succeeded (DXGI API is supported and probing succeeded)

Precondition:

m_exists: m!=0

info_exist: info!=0

void vtkDirectXGPUInfoList::ProbeInfoWithWMI	(	HMONITOR	m,
		vtkGPUInfo *	info
	)		[protected]

Probe the GPUs with the WMI api (Windows XP or later).

Precondition:

m_exists: m!=0

info_exist: info!=0

bool vtkDirectXGPUInfoList::GetDeviceIDFromHMonitor	(	HMONITOR	hm,
		WCHAR *	strDeviceID,
		int	cchDeviceID
	)		[protected]

Used by ProbeInfoWithWMI().

Precondition:

pre hm_exists: hm!=0

strDeviceID_exists: strDeviceID!=0

cchDeviceID_is_positive: cchDeviceID>0
