Member Enumeration Documentation

enum SoHardwareQuery::HW_Feature

Enumerator:

HW_3DTEXMAP	The system supports OpenGL 3D texture mapping. On some boards, this query may return TRUE even if your board does not support accelerated 3D textures. In this case performance may be slow, and you may prefer to use 2D textures instead. Note: The inability to determine if 3D textures are accelerated is a limitation of OpenGL, not Open Inventor.
HW_TEXCOLORMAP	The system supports the OpenGL paletted texture extension and/or the texture color table extension.
HW_TEXCOMPRESSION	The system supports the OpenGL texture compression extension.

enum SoHardwareQuery::HW_SupportStatus

Enumerator:

NO
YES
UNKNOWN

Member Function Documentation

static SoType SoHardwareQuery::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from SoNode.

virtual SoType SoHardwareQuery::getTypeId

(

)

const [virtual]

Returns the type identifier for this specific instance.

Reimplemented from SoNode.

static HW_SupportStatus SoHardwareQuery::isSupported

(

HW_Feature

feature

)

[static]

Returns information about hardware support for various volume rendering features.

This query is only valid after SoVolumeRendering::init has been called. Otherwise the return value will be UNKNOWN. When using a debug build of Open Inventor, some "no context available" warning messages may be generated. You can ignore them or see SoGLExtension for an example of using SoGLContext to avoid them.
