The destructor.

Member Function Documentation

void * SoMultiTextureEnabledElement::createInstance ( void )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoMultiTextureEnabledElement::init ( SoState * state )

virtual

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.

Reimplemented from SoElement.

SbBool SoMultiTextureEnabledElement::get	(	SoState *	state,
		const int	unit = `0`
	)

static

Return current state of this element for unit.

void SoMultiTextureEnabledElement::setElt	(	const int	unit,
		const int	mode_in
	)

virtual

virtual element set function.

void SoMultiTextureEnabledElement::push ( SoState * state )

virtual

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.

Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().

Reimplemented from SoElement.

SbBool SoMultiTextureEnabledElement::matches ( const SoElement * element ) const

virtual

This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.

If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.

Implements SoElement.

SoElement * SoMultiTextureEnabledElement::copyMatchInfo ( void ) const

virtual

This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scenegraph traversal caching operations.

Implements SoElement.

const SbBool * SoMultiTextureEnabledElement::getEnabledUnits	(	SoState *	state,
		int &	lastenabled
	)

static

Returns a pointer to a boolean array. TRUE means unit is enabled and that texture coordinates must be sent to the unit. lastenabled is set to the last enabled unit.

const SoMultiTextureEnabledElement::Mode * SoMultiTextureEnabledElement::getActiveUnits	(	SoState *	state,
		int &	lastenabled
	)

static

Returns the mode of all units. Also returns the last enabled unit in lastenabled.

Since: Coin 2.5

void SoMultiTextureEnabledElement::enableRectangle	(	SoState *	state,
		SoNode *	node,
		const int	unit = `0`
	)

static

Enable RECTANGLE texture mode.

Since: Coin 2.5

void SoMultiTextureEnabledElement::enableCubeMap	(	SoState *	state,
		SoNode *	node,
		const int	unit = `0`
	)

static

Enable CUBEMAP texture mode.

Since: Coin 2.5

void SoMultiTextureEnabledElement::enableTexture3	(	SoState *	state,
		SoNode *	node,
		const int	unit = `0`
	)

static

Enable Texture3 texture mode.

Since: Coin 4.0

SoMultiTextureEnabledElement::Mode SoMultiTextureEnabledElement::getMode	(	SoState *	state,
		const int	unit = `0`
	)

static

Returns the mode for a texture unit.

Since: Coin 2.5

void SoMultiTextureEnabledElement::disableAll ( SoState * state )

static

Disable all active texture units. Convenient when all textures needs to be disabled before rendering.

Since: Coin 2.5

void SoMultiTextureEnabledElement::set	(	SoState *	state,
		const SbBool	enabled
	)

inlinestatic

Coin-3 support.

void SoMultiTextureEnabledElement::set	(	SoState *	state,
		SoNode *	node,
		const SbBool	enabled
	)

inlinestatic

Coin-3 support.

int SoMultiTextureEnabledElement::getMaxUnits ( ) const

protected

Returns the max number of texture units enabled/disabled

Since: Coin 4.0

SbBool SoMultiTextureEnabledElement::isEnabled ( const int unit ) const

protected

Returns TRUE if unit is enabled (Mode == DISABLED).
