Detailed Description

The SoMFVec3f class is a container for SbVec3f vectors. This field is used where nodes, engines or other field containers need to store an array of vectors with three elements.

This field supports application data sharing through a setValuesPointer() method. See SoMField documentation for information on how to use this function.

Member Function Documentation

  void * SoMFVec3f::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.

  SoType SoMFVec3f::getClassTypeId (void) [static]
This static method returns the SoType object associated with objects of this class.

  SoType SoMFVec3f::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoField. This is used for runtime type checking and 'downward' casting.

Implements SoField.

  void SoMFVec3f::copyFrom (const SoField & f) [virtual]
Copy value(s) from f into this field. f must be of the same type as this field.

Implements SoField.

  SbBool SoMFVec3f::isSame (const SoField & f) const [virtual]
Check for equal type and value(s).

Implements SoField.

  void SoMFVec3f::deleteAllValues (void) [protected], [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoMField.

  void SoMFVec3f::copyValue (int to, int from) [protected], [virtual]
This method is used for moving values around internally within a multivalue field. It needs to be overridden in each field so it automatically takes care of running copy contructors where necessary.

Implements SoMField.

  const SbVec3f* SoMFVec3f::getValues (const int start) const [inline]
Returns a pointer to the values array.

  void SoMFVec3f::initClass (void) [static]
Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.

  void SoMFVec3f::setValues (int start, int numarg, const float xyz[][3])
Set num vector array elements from the xyz array, reading from index 0 in the given float-triplet vector array and storing values from index start in this SoMFVec3f's array.

If start + num is larger than the current number of elements in the SoMFVec3f field, this method will automatically expand the field to accommodate all given float-vector element values.

  void SoMFVec3f::set1Value (int idx, float x, float y, float z)
Set the vector at idx.

  void SoMFVec3f::set1Value (int idx, const float xyz[3])
Set the vector at idx.

  void SoMFVec3f::setValue (float x, float y, float z)
Set this field to contain a single vector with the given element values.

  void SoMFVec3f::setValue (const float xyz[3])
Set this field to contain a single vector with the given element values.
