Returned value indicates if it is successful.

◆ getActiveTextureUnit()

static int SoTextureUnitElement::getActiveTextureUnit ( SoState state)
static

Returns the current active texture unit (the last texture unit set).

◆ getClassStackIndex()

static int SoTextureUnitElement::getClassStackIndex ( )
static

Returns the stack id for this element.


◆ getClassTypeId()

static SoType SoTextureUnitElement::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getMaxTextureUnit()

static int SoTextureUnitElement::getMaxTextureUnit ( SoState state = NULL)
static

Returns the maximum texture units.

◆ getTextureUnits()

static const SbIntList & SoTextureUnitElement::getTextureUnits ( SoState state)
static

◆ isMultiTexturing()

static SbBool SoTextureUnitElement::isMultiTexturing ( SoState state,
SbIntList &  imageTexUnitList 
)
static

Returns TRUE if the multi-texturing is active: i.e., at least 2 texture units are defined.

Returns also the list of units.

◆ pop()

virtual void SoTextureUnitElement::pop ( SoState ,
const SoElement prevTopElement 
)
virtual

static void SoTextureUnitElement::set ( SoState state,
SoNode node,
int  unit 
)
static

Sets the current texture unit.
