## Detailed Description

The **SoVRMLIndexedShape** class is a superclass for geometry that use indexes.

## Constructor & Destructor Documentation

### SoVRMLIndexedShape::SoVRMLIndexedShape (void ) \[protected\]

Constructor.

### SoVRMLIndexedShape::~SoVRMLIndexedShape () \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoVRMLIndexedShape::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### SoType SoVRMLIndexedShape::getTypeId (void ) const \[virtual\]

Returns the type identification of an object derived from a class inheriting **SoBase**. This is used for runtime type checking and "downward" casting.

Reimplemented from **SoVRMLVertexShape**.

Reimplemented in **SoVRMLIndexedFaceSet**.

### const SoFieldData \*\* SoVRMLIndexedShape::getFieldDataPtr (void ) \[static\], \[protected\]

*This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\

 Returns the **SoFieldData** class which holds information about fields in this node.

### const SoFieldData \* SoVRMLIndexedShape::getFieldData (void ) const \[protected\], \[virtual\]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from **SoVRMLVertexShape**.

Reimplemented in **SoVRMLIndexedFaceSet**.

### void SoVRMLIndexedShape::initClass (void ) \[static\]

### void SoVRMLIndexedShape::notify (SoNotList \* l) \[protected\], \[virtual\]

Notifies all auditors for this instance when changes are made.

Reimplemented from **SoVRMLVertexShape**.

### void SoVRMLIndexedShape::computeBBox (SoAction \* action, SbBox3f & box, SbVec3f & center) \[protected\], \[virtual\]

Implemented by **SoShape** subclasses to let the **SoShape** superclass know the exact size and weighted center point of the shape's bounding box.

The bounding box and center point should be calculated and returned in the local coordinate system.

The method implements action behavior for shape nodes for **SoGetBoundingBoxAction**. It is invoked from **SoShape::getBoundingBox()**. (Subclasses should *not* override **SoNode::getBoundingBox()**.)

The *box* parameter sent in is guaranteed to be an empty box, while *center* is undefined upon function entry.

Implements **SoShape**.

### SbBool SoVRMLIndexedShape::getVertexData (SoState \* state, const SoCoordinateElement \*& coords, const SbVec3f \*& normals, const int32\_t \*& cindices, const int32\_t \*& nindices, const int32\_t \*& tindices, const int32\_t \*& mindices, int & numcindices, const SbBool neednormals, SbBool & normalcacheused) \[protected\]

Convenience method that will fetch data needed for rendering or generating primitives. Takes care of normal cache.
