Detailed Description
Stores the current coordinates.
This element stores the current coordinates. Coordinates may be specified as 3-D or 4-D vectors. This element remembers the last type of value stored.
This class allows read-only access to the top element in the state to make accessing several values in it more efficient. Individual values must be accessed through this instance.

| const SbVec3f& SoCoordinateElement::get3 | ( | int | index | ) | const |
Returns the indexed coordinate from an element as a 3-vector, converting if necessary.
A returned reference may be invalid after the next call to this method or the get4() method.
| const SbVec4f& SoCoordinateElement::get4 | ( | int | index | ) | const |
Returns the indexed coordinate from an element as a 4-vector, converting if necessary.
A returned reference may be invalid after the next call to this method or the get3() method.
| static int SoCoordinateElement::getClassStackIndex | ( | ) | [static] |
Returns the stack id for this element.
Reimplemented from SoReplacedElement.
| static SoType SoCoordinateElement::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoReplacedElement.
| const SbVec3f* SoCoordinateElement::getCoord3 | ( | ) | const [inline] |
Returns the array of SbVec3f without any conversion.
The pointer may be NULL if coordinates are specified as 4D vectors.
| const SbVec4f* SoCoordinateElement::getCoord4 | ( | ) | const [inline] |
Returns the array of SbVec4f without any conversion.
The pointer may be NULL if coordinates are specified as 3D vectors.
| static SbVec3f SoCoordinateElement::getDefault3 | ( | ) | [inline, static] |
Returns the default 3-D coordinate.
| static SbVec4f SoCoordinateElement::getDefault4 | ( | ) | [inline, static] |
Returns the default 4-D coordinate.
| static const SoCoordinateElement* SoCoordinateElement::getInstance | ( | SoState * | state | ) | [inline, static] |
Returns the top (current) instance of the element in the state.
| int32_t SoCoordinateElement::getNum | ( | ) | const [inline] |
Returns the number of coordinate points in an instance.
| SbBool SoCoordinateElement::is3D | ( | ) | const [inline] |
Returns TRUE if the coordinates were specified as 3-vectors, FALSE if 4-vectors.
| virtual void SoCoordinateElement::print | ( | FILE * | fp | ) | const [virtual] |
Prints element (for debugging).
Reimplemented from SoReplacedElement.
