## Detailed Description

The **SoIndexedShape** class is the superclass for all indexed vertex shapes.

This is an abstract class which contains storage for four fields for indices to coordinates, normals, materials and texture coordinates for its subclasses.

## Constructor & Destructor Documentation

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

Constructor.

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

Destructor.

## Member Function Documentation

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

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

### SoType SoIndexedShape::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 **SoVertexShape**.

Reimplemented in **SoIndexedFaceSet**, **SoIndexedLineSet**, **SoIndexedMarkerSet**, **SoIndexedPointSet**, and **SoIndexedTriangleStripSet**.

### const SoFieldData \*\* SoIndexedShape::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 \* SoIndexedShape::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 **SoVertexShape**.

Reimplemented in **SoIndexedFaceSet**, **SoIndexedLineSet**, **SoIndexedMarkerSet**, **SoIndexedPointSet**, and **SoIndexedTriangleStripSet**.

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

### void SoIndexedShape::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**.

### int SoIndexedShape::getNumVerts (const int startCoord) \[protected\]

Starting at index position *startCoord*, returns the number of indices until either the end of index array or a separator index (-1).

### void SoIndexedShape::setupIndices (const int numParts, const int numFaces, const SbBool needNormals, const SbBool needTexCoords) \[protected\]

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

### const int32\_t \* SoIndexedShape::getNormalIndices (void ) \[protected\]

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

### const int32\_t \* SoIndexedShape::getColorIndices (void ) \[protected\]

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

### const int32\_t \* SoIndexedShape::getTexCoordIndices (void ) \[protected\]

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

### SbBool SoIndexedShape::areTexCoordsIndexed (SoAction \* action) \[static\], \[protected\]

Returns whether texture coordinates should be indexed or not.

**See also**

**SoTextureCoordinateBinding**

### SbBool SoIndexedShape::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.

This method was not part of the original SGI Open Inventor API, and is an extension specific for Coin.
