Member Function Documentation

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.

static SoType SoTextureUnitElement::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoAccumulatedElement.

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.

Reimplemented from SoAccumulatedElement.

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

Sets the current texture unit.
