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.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLTextureUnitElement.

static SoType SoTextureUnitElement::getClassTypeId

(

)

[static]

static SoDEPRECATED const MappingMethod* SoTextureUnitElement::getMappingMethods

(

SoState *

state

)

[static]

Returns the mapping method associated with each texture unit.

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 int SoTextureUnitElement::isBumpMapping

(

SoState *

state

)

[static]

Indicate if one unit among the current unit list corresponds to an BUMP_MAPPING.

The first corresponding unit found is returned, -1 otherwise.

static int SoTextureUnitElement::isImageMapping

(

SoState *

state

)

[static]

Indicate if one unit among the current unit list corresponds to an IMAGE_MAPPING.

The first corresponding unit found is returned, -1 otherwise.

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 with a mapping method equal to IMAGE_MAPPING.

Returns also the list of units where the mapping method is equal to IMAGE_MAPPING.

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

Pop method.

Reimplemented in SoGLTextureUnitElement.

virtual void SoTextureUnitElement::push

(

SoState *

state

)

[virtual]

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

Reimplemented from SoAccumulatedElement.

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

Sets the current texture unit and mapping method.

Deprecated:

Deprecated since Open Inventor 10000
No more used.

static SbBool SoTextureUnitElement::shouldSendGLData

(

SoState *

state

)

[static]

Indicate according to the current mapping method if GL data must be sent or not.
