## Detailed Description

The **SoNonIndexedShape** class is the superclass for all non-indexed vertex based shapes.

It contains the (now obsoleted) startIndex field and a convenience method for calculating the bounding box.

## Constructor & Destructor Documentation

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

Constructor.

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

Destructor.

## Member Function Documentation

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

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

### SoType SoNonIndexedShape::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 **SoFaceSet**, **SoLineSet**, **SoMarkerSet**, **SoPointSet**, **SoQuadMesh**, and **SoTriangleStripSet**.

### const SoFieldData \*\* SoNonIndexedShape::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 \* SoNonIndexedShape::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 **SoFaceSet**, **SoLineSet**, **SoMarkerSet**, **SoPointSet**, **SoQuadMesh**, and **SoTriangleStripSet**.

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

### void SoNonIndexedShape::computeCoordBBox (SoAction \* action, int numVertices, SbBox3f & box, SbVec3f & center) \[protected\]

This method is provided as a convenient means for the subclasses of this class to find their bounding box and center value.

The returned bounding box will enclose all vertices from *startIndex* up to *startIndex* + *numVertices*. If *numVertices* is less than zero, *all* vertices in the current coordinate element or vertex property node will be used in the calculation.

The *center* point will be calculated as the average of all the vertices in the bounding box.

### void SoNonIndexedShape::fixNumVerticesPointers (SoState \* state, const int32\_t \*& start, const int32\_t \*& end, int32\_t \* dummyarray) const \[protected\]

Convenience method that might adjust *start* and *end* pointers, which should point at the start and end of the numVertices array when calling this method. This takes care of the case where numVertices contains a single -1, and all coordinates in the state (or in the vertexProperty field) should be rendered as one primitive.

*dummyarray* should be a temporary array, with room for one integer.

Not part of the OIV API.

## Member Data Documentation

### SoSFInt32 SoNonIndexedShape::startIndex

Coordinates are fetched from this index on. This field is now obsoleted, and is provided only for backward compatibility.
