Detailed Description

OpenGL device management class

This class provides functions to discover, and query information about, GPU devices available in the system through the OpenGL API. You can query, for example, the total memory available on the device.

Please see SoDevice for general information about the device classes.

See SoGLScreenDevice for information about displays attached to a GPU.

Member Function Documentation

exitClass()

static void SoGLDevice::exitClass ( )

static

Cleans SoGLDevice.

findFirstAvailableDevice()

static SoGLDevice * SoGLDevice::findFirstAvailableDevice ( )

static

Returns the first available device found in the system.

Since Open Inventor version 9.7.2, this is guaranteed to be the device that Open Inventor will actually use for rendering.

getAvailableMemory()

virtual unsigned long long SoGLDevice::getAvailableMemory ( ) const

virtual

Returns the currently available memory of this device in bytes.

IMPORTANT NOTE: This function may returns the same value as getTotalMemory() because of driver limitations.

Implements SoDevice.

getDevice()

static SoGLDevice * SoGLDevice::getDevice ( int  index )

static

Returns the SoGLDevice indicated by index (starting from 0).

Parameters

index

The index of the SoGLDevice.

getDeviceName()

SbString SoGLDevice::getDeviceName ( ) const

inlinevirtual

Returns the name of this device.

Implements SoDevice.

Definition at line 260 of file SoGLDevice.h.

getDevicesCount()

static unsigned int SoGLDevice::getDevicesCount ( )

static

Returns the number of GPUs on the sytem.

getDeviceSettings()

virtual SoGLDeviceSettings * SoGLDevice::getDeviceSettings ( ) const

virtual

Returns an handle of the driver API allowing to modify profile of this device.

The return is depending of the driver manufacturer (NVidia, AMD, Intel...). Returns NULL if the API is not available. E.g.: For Intel driver, NULL is always returned.

getDriverVersion()

virtual SbString SoGLDevice::getDriverVersion ( ) const

virtual

Returns the driver version of this GPU.

Implements SoDevice.

getLogicalUnits()

unsigned int SoGLDevice::getLogicalUnits ( ) const

inlinevirtual

Returns the number of logical units on this device (i.e.

the number of cores of this GPU).

Implements SoDevice.

Definition at line 254 of file SoGLDevice.h.

getMainScreenDevice()

SoGLScreenDevice * SoGLDevice::getMainScreenDevice

(

)

Returns the main screen device connected to the GL device.

getScreenDevice()

SoGLScreenDevice * SoGLDevice::getScreenDevice

(

int

index

)

Returns the SoGLScreenDevice indicated by index (starting from 0).

Parameters

index

The index of the SoGLScreenDevice.

getScreenDevicesCount()

unsigned int SoGLDevice::getScreenDevicesCount

(

)

Returns the number of screen devices connected to the GL device.

getTotalMemory()

unsigned long long SoGLDevice::getTotalMemory ( ) const

inlinevirtual

Returns the total memory of this device in bytes.

Implements SoDevice.

Definition at line 248 of file SoGLDevice.h.

initClass()

static void SoGLDevice::initClass ( )

static

Initializes SoGLDevice.
