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