Member Function Documentation

get()

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.)

get3()

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.

get4()

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

getClassStackIndex()

static int SoTextureCoordinate3Element::getClassStackIndex ( )

static

Returns the stack id for this element.

getClassTypeId()

static SoType SoTextureCoordinate3Element::getClassTypeId ( )

static

Returns the type identifier for this class.

getInstance()

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.

getNum()

int32_t SoTextureCoordinate3Element::getNum

(

int

unit = 0

)

const

Returns the number of coordinate points in an instance.

getType() [1/2]

virtual CoordType SoTextureCoordinate3Element::getType ( int  unit = 0 ) const

virtual

getType() [2/2]

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

static

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

is3D()

SbBool SoTextureCoordinate3Element::is3D

(

int

unit = 0

)

const

isForceSending()

SbBool SoTextureCoordinate3Element::isForceSending

(

int

unit = 0

)

const

print()

virtual void SoTextureCoordinate3Element::print ( FILE *  fp ) const

virtual

Prints element (for debugging).

Reimplemented from SoReplacedTextureElement.

push()

virtual void SoTextureCoordinate3Element::push ( SoState *  )

virtual

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

Reimplemented from SoReplacedTextureElement.

set3()

static

set4()

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

static

setDefault()

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):

setFunction()

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