Detailed Description

The SoVertexShape class is the superclass for all vertex based shapes.

Basically, every polygon, line, or point based shape will inherit this class. It contains methods for organizing the normal cache, and also holds the SoVertexShape::vertexProperty field which can be used to set vertex data inside the node.

Constructor & Destructor Documentation

◆ SoVertexShape()

SoVertexShape::SoVertexShape ( void )
protected

Constructor.

◆ ~SoVertexShape()

SoVertexShape::~SoVertexShape ( )
protectedvirtual

Destructor.

Member Function Documentation

◆ generateAndReadLockNormalCache()

SoNormalCache * SoVertexShape::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 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.

Since
Coin 2.0

◆ generateDefaultNormals() [1/2]

SbBool SoVertexShape::generateDefaultNormals ( SoState * state,
SoNormalBundle * bundle )
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 SoIndexedFaceSet, SoIndexedPointSet, SoPointSet, SoFaceSet, SoIndexedTriangleStripSet, SoQuadMesh, and SoTriangleStripSet.

◆ generateDefaultNormals() [2/2]

SbBool SoVertexShape::generateDefaultNormals ( SoState * state,
SoNormalCache * cache )
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 SoFaceSet, SoQuadMesh, SoTriangleStripSet, SoIndexedPointSet, SoPointSet, SoIndexedFaceSet, and SoIndexedTriangleStripSet.

◆ getClassTypeId()

SoType SoVertexShape::getClassTypeId ( void )
static

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

◆ getFieldData()

const SoFieldData * SoVertexShape::getFieldData ( void ) const
protectedvirtual

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

Reimplemented from SoShape.

Reimplemented in SoFaceSet, SoIndexedFaceSet, SoIndexedLineSet, SoIndexedMarkerSet, SoIndexedPointSet, SoIndexedShape, SoIndexedTriangleStripSet, SoLineSet, SoMarkerSet, SoNonIndexedShape, SoPointSet, SoQuadMesh, and SoTriangleStripSet.

◆ getFieldDataPtr()

const SoFieldData ** SoVertexShape::getFieldDataPtr ( void )
staticprotected

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.

◆ getNormalCache()

SoNormalCache * SoVertexShape::getNormalCache ( void ) const
protected

Returns the current normal cache, or NULL if there is none.

◆ getTypeId()

SoType SoVertexShape::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 SoShape.

Reimplemented in SoFaceSet, SoIndexedFaceSet, SoIndexedLineSet, SoIndexedMarkerSet, SoIndexedPointSet, SoIndexedShape, SoIndexedTriangleStripSet, SoLineSet, SoMarkerSet, SoNonIndexedShape, SoPointSet, SoQuadMesh, and SoTriangleStripSet.

◆ getVertexData()

void SoVertexShape::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 Open Inventor API.

◆ initClass()

void SoVertexShape::initClass ( void )
static

◆ notify()

void SoVertexShape::notify ( SoNotList * l)
virtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoShape.

Reimplemented in SoIndexedLineSet, and SoIndexedPointSet.

◆ readLockNormalCache()

void SoVertexShape::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.

readUnlockNormalCache()
Since
Coin 2.0

◆ readUnlockNormalCache()

void SoVertexShape::readUnlockNormalCache ( void )
protected

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

See also
readLockNormalCache()
Since
Coin 2.0

◆ setNormalCache()

void SoVertexShape::setNormalCache ( SoState *const state,
const int num,
const SbVec3f * normals )
protected

Sets normal cache to contain the normals specified by normals and num, and forces cache dependencies on coordinates, shape hints and crease angle.

◆ shouldGLRender()

SbBool SoVertexShape::shouldGLRender ( SoGLRenderAction * action)
protectedvirtual

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

Reimplemented from SoShape.

◆ write()

void SoVertexShape::write ( SoWriteAction * action)
virtual

Action method for SoWriteAction.

Writes out a node object, and any connected nodes, engines etc, if necessary.

Reimplemented from SoNode.

Member Data Documentation

◆ vertexProperty

SoSFNode SoVertexShape::vertexProperty

If you set the vertexProperty field, it should be with an SoVertexProperty node. Otherwise it will simply be ignored. Node types inheriting SoVertexShape will then get their coordinate data from the vertexProperty node instead of from the global traversal state.

The vertexProperty field of SoVertexShape-derived nodes breaks somewhat with the basic design of Open Inventor, as its contents are not passed to the global state. This is done to provide a simple path to highly optimized rendering of vertex based shapes.
