Member Function Documentation
void SoVRMLVertexShape::initClass (void) [static] Sets up initialization
for data common to all instances of this class, like submitting
necessary information to the Coin type system.
Reimplemented from SoVRMLGeometry.
Reimplemented in SoVRMLIndexedFaceSet, and SoVRMLIndexedShape.
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 who wants to throw geometry primitives at
OpenGL overrides 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 calculates their bounding box also
overrides 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
