Member Function Documentation

const SbVec4f& SoTextureCoordinate3Element::get	(	const SbVec3f &	point,
		const SbVec3f &	normal,
		int	unit = 0
	)			const

Given point and normal, returns texture coordinate.

(The r coordinate will be 0.0 and the q will be 1.0 until we get 3D texture coordinate functions.)

const SbVec3f& SoTextureCoordinate3Element::get3	(	int	index,
		int	unit = 0
	)			const

Returns the indexed coordinate from an element as a 3- or 4-vector, converting if necessary.

const SbVec4f& SoTextureCoordinate3Element::get4	(	int	index,
		int	unit = 0
	)			const

static int SoTextureCoordinate3Element::getClassStackIndex

(

)

[static]

Returns the stack id for this element.

Reimplemented from SoReplacedTextureElement.

Reimplemented in SoGLTextureCoordinate3Element.

static SoType SoTextureCoordinate3Element::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from SoReplacedTextureElement.

Reimplemented in SoGLTextureCoordinate3Element.

static const SoTextureCoordinate3Element* SoTextureCoordinate3Element::getInstance

(

SoState *

state

)

[static]

Returns the top (current) instance of the element in the state.

The get routines are called on an instance because it is more efficient than calling a static method that looks up the element in the state for every coordinate.

Reimplemented in SoGLTextureCoordinate3Element.

int32_t SoTextureCoordinate3Element::getNum

(

int

unit = 0

)

const

Returns the number of coordinate points in an instance.

virtual CoordType SoTextureCoordinate3Element::getType

(

int

unit = 0

)

const [virtual]

Reimplemented in SoGLTextureCoordinate3Element.

static CoordType SoTextureCoordinate3Element::getType	(	SoState *	state,
		int	unit = 0
	)			[static]

Returns code indicating what has been set in state/element.

SbBool SoTextureCoordinate3Element::is3D

(

int

unit = 0

)

const

SbBool SoTextureCoordinate3Element::isForceSending

(

int

unit = 0

)

const

virtual void SoTextureCoordinate3Element::print

(

FILE *

fp

)

const [virtual]

Prints element (for debugging).

Reimplemented from SoReplacedTextureElement.

virtual void SoTextureCoordinate3Element::push

(

SoState *

)

[virtual]

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

Reimplemented from SoReplacedTextureElement.

Reimplemented in SoGLTextureCoordinate3Element.

static void SoTextureCoordinate3Element::set3	(	SoState *	state,
		SoNode *	node,
		int32_t	numCoords,
		const SbVec3f *	coords,
		SbBool	frcSend = FALSE
	)			[static]

static void SoTextureCoordinate3Element::set4	(	SoState *	state,
		SoNode *	node,
		int32_t	numCoords,
		const SbVec4f *	coords,
		SbBool	frcSend = FALSE
	)			[static]

static void SoTextureCoordinate3Element::setDefault	(	SoState *	state,
		SoNode *	node
	)			[static]

Sets the current texture coordinates, in any of several ways: EXPLICIT, no coordinates (shapes will generate):.

static void SoTextureCoordinate3Element::setFunction	(	SoState *	state,
		SoNode *	node,
		SoTextureCoordinate3FunctionCB *	func,
		void *	userData,
		SbBool	frcSend = FALSE
	)			[static]
