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.

static SoType SoTextureCoordinate3Element::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoReplacedTextureElement.

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.

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]
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.

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,
