Detailed Description

Stores the current texture unit identifier.

This element stores the the current texture unit identifier.

static SbBool SoTextureUnitElement::activateTextureUnit	(	SoState *	state,
		int	unit
	)			`[static]`

Activates the current texture if it exists.

Returned value indicates if it is successful.

static int SoTextureUnitElement::getActiveTextureUnit ( SoState * state ) [static]

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

static int SoTextureUnitElement::getClassStackIndex ( ) [static]

Returns the stack id for this element.

static SoType SoTextureUnitElement::getClassTypeId ( ) [static]

Returns the type identifier for this class.

static int SoTextureUnitElement::getMaxTextureUnit ( SoState * state = NULL ) [static]

Returns the maximum texture units.

static const SbIntList& SoTextureUnitElement::getTextureUnits ( SoState * state ) [static]

Returns the current list texture units.

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.

virtual void SoTextureUnitElement::pop	(	SoState *	,
		const SoElement *	prevTopElement
	)			`[virtual]`

Pop method.

virtual void SoTextureUnitElement::push ( SoState * state ) [virtual]

Overrides push() method to copy values from next instance in the stack.

static void SoTextureUnitElement::set	(	SoState *	state,
		SoNode *	node,
		int	unit
	)			`[static]`

Sets the current texture unit.
