Detailed Description

The SoMultiTextureCoordinateElement class is yet to be documented. FIXME: write doc.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since
    Coin 2.2

Member Function Documentation

  SoType SoMultiTextureCoordinateElement::getClassTypeId (void) [static]
This static method returns the SoType object associated with objects of this class.

  int SoMultiTextureCoordinateElement::getClassStackIndex (void) [static]
This static method returns the state stack index for the class.

  void * SoMultiTextureCoordinateElement::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.
 Creates a new instance of the class type corresponding to the SoType object.

  void SoMultiTextureCoordinateElement::initClass (void) [static]
Initialize relevant common data for all instances, like the type system.

  void SoMultiTextureCoordinateElement::set3 (SoState *const state, SoNode *const node, const int unit, const int32_t numCoords, const SbVec3f *const coords) [static]
FIXME: write doc.

  SoMultiTextureCoordinateElement::CoordType SoMultiTextureCoordinateElement::getType (SoState *const state, const int unit = 0) [static]
This method is used by shapes. Three return values are possible.

DEFAULT means that the shapes should generate their own texture coordinates.

EXPLICIT means that discrete texture coordinates are stored, and should be fetched with get2(), get3() or get4().

FUNCTION means that get(point, normal) must be used to generate texture coordinates.

  const SbVec4f & SoMultiTextureCoordinateElement::get (const int unit, const SbVec3f & point, const SbVec3f & normal) const
This method returns texture coordinate for the given point and normal. The coordinate is returned as a 4D vector where the r and q coordinates may be set to 0 and 1 respectively depending on what texture coordinate dimension we're using.

This method should only be used if the CoordType is FUNCTION.

  int32_t SoMultiTextureCoordinateElement::getDimension (const int unit = 0) const
FIXME: write doc.

  const SbVec3f & SoMultiTextureCoordinateElement::get3 (const int unit, const int index) const
FIXME: write doc.

  const SbVec2f * SoMultiTextureCoordinateElement::getArrayPtr2 (const int unit = 0) const
Returns a pointer to the 2D texture coordinate array. This method is not part of the OIV API.

  const SbVec3f * SoMultiTextureCoordinateElement::getArrayPtr3 (const int unit = 0) const
Returns a pointer to the 3D texture coordinate array.

  const SbVec4f * SoMultiTextureCoordinateElement::getArrayPtr4 (const int unit = 0) const
Returns a pointer to the 4D texture coordinate array. This method is not part of the OIV API.

  void SoMultiTextureCoordinateElement::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.

Reimplemented in SoGLMultiTextureCoordinateElement.

  SbBool SoMultiTextureCoordinateElement::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 * SoMultiTextureCoordinateElement::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 scene graph traversal caching operations.

Implements SoElement.

  SoMultiTextureCoordinateElement::UnitData & SoMultiTextureCoordinateElement::getUnitData (const int unit) [protected]
Returns the per-unit data for this element.
