## Detailed Description

The **SoVRMLVertexShape** class is a superclass for vertex based shapes.

## Constructor & Destructor Documentation

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

Constructor.

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

Destructor.

## Member Function Documentation

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

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

### SoType SoVRMLVertexShape::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 **SoVRMLGeometry**.

Reimplemented in **SoVRMLIndexedFaceSet**, and **SoVRMLIndexedShape**.

### const SoFieldData \*\* SoVRMLVertexShape::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 \* SoVRMLVertexShape::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 **SoVRMLGeometry**.

Reimplemented in **SoVRMLIndexedFaceSet**, and **SoVRMLIndexedShape**.

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

### SbBool SoVRMLVertexShape::generateDefaultNormals (SoState \* s, SoNormalBundle \* nb) \[virtual\]

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

 Subclasses should override this method to generate default normals using the **SoNormalBundle** class. TRUE should be returned if normals were generated, FALSE otherwise.

Default method returns FALSE.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\

Reimplemented in **SoVRMLIndexedFaceSet**.

### SbBool SoVRMLVertexShape::generateDefaultNormals (SoState \* s, SoNormalCache \* nc) \[virtual\]

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

 Subclasses should override this method to generate default normals using the **SoNormalCache** class. This is more effective than using **SoNormalGenerator**. Return TRUE if normals were generated, FALSE otherwise.

Default method just returns FALSE.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\

Reimplemented in **SoVRMLIndexedFaceSet**.

### void SoVRMLVertexShape::doAction (SoAction \* action) \[virtual\]

This function performs the typical operation of a node for any action.

Reimplemented from **SoNode**.

### void SoVRMLVertexShape::GLRender (SoGLRenderAction \* action) \[virtual\]

Action method for the **SoGLRenderAction**.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from **SoShape**.

Reimplemented in **SoVRMLIndexedFaceSet**.

### void SoVRMLVertexShape::getBoundingBox (SoGetBoundingBoxAction \* action) \[virtual\]

Action method for the **SoGetBoundingBoxAction**.

Calculates bounding box and center coordinates for node and modifies the values of the *action* to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from **SoShape**.

### void SoVRMLVertexShape::callback (SoCallbackAction \* action) \[virtual\]

Action method for **SoCallbackAction**.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the **SoCallbackAction** for extracting information about the scene graph.

Reimplemented from **SoShape**.

### void SoVRMLVertexShape::pick (SoPickAction \* action) \[virtual\]

Action method for **SoPickAction**.

Does common processing for **SoPickAction** *action* instances.

Reimplemented from **SoNode**.

### void SoVRMLVertexShape::notify (SoNotList \* l) \[virtual\]

Notifies all auditors for this instance when changes are made.

Reimplemented from **SoVRMLGeometry**.

Reimplemented in **SoVRMLIndexedShape**.

### SbBool SoVRMLVertexShape::shouldGLRender (SoGLRenderAction \* action) \[protected\], \[virtual\]

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

Reimplemented from **SoVRMLGeometry**.

### SoNormalCache \* SoVRMLVertexShape::generateAndReadLockNormalCache (SoState \*const state) \[protected\]

Convenience method that can be used by subclasses to return or create a normal cache. If the current cache is not valid, it takes care of unrefing the old cache and pushing and popping the state to create element dependencies when creating the new cache.

When returning from this method, the normal cache will be read locked, and the caller should call **readUnlockNormalCache()** when the normals in the cache is no longer needed.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\

**Since**

Coin 2.0

### void SoVRMLVertexShape::getVertexData (SoState \* state, const SoCoordinateElement \*& coords, const SbVec3f \*& normals, const SbBool neednormals) \[protected\]

Convenience method that returns the current coordinate and normal element. This method is not part of the OIV API.

### void SoVRMLVertexShape::readLockNormalCache (void ) \[protected\]

Read lock the normal cache. This method should be called before fetching the normal cache (using getNormalCache()). When the cached normals are no longer needed, **readUnlockNormalCache()** must be called.

It is also possible to use **generateAndReadLockNormalCache()**.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\

**See also**

**readUnlockNormalCache()**

**Since**

Coin 2.0

### void SoVRMLVertexShape::readUnlockNormalCache (void ) \[protected\]

Read unlock the normal cache. Should be called when the read-locked cached normals are no longer needed.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\

**See also**

**readLockNormalCache()**

**Since**

Coin 2.0
