Detailed Description

The SoRotationXYZ class is a node type for specifying rotation around a particular axis.

Application programmers can use nodes of this type instead of SoRotation nodes for simplicity and clarity if the rotation will only happen around one particular axis.

Using SoRotationXYZ nodes are also simpler and more efficient than using SoRotation nodes if you are connecting engines to rotation angles for animation purposes.

        angle 0

Member Function Documentation

SoType SoRotationXYZ::getClassTypeId (void) [static]

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

Reimplemented from SoTransformation.

SoType SoRotationXYZ::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

  void foo(SoNode * node)
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoTransformation.

const SoFieldData ** SoRotationXYZ::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.

Reimplemented from SoTransformation.

const SoFieldData * SoRotationXYZ::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 SoTransformation.

void SoRotationXYZ::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 SoTransformation.

SbRotation SoRotationXYZ::getRotation (void) const

Returns an SbRotation object with values set up to correspond with the specified rotation of the node.

void SoRotationXYZ::doAction (SoAction *action) [virtual]

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

Reimplemented from SoNode.

void SoRotationXYZ::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 SoNode.

void SoRotationXYZ::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 SoNode.

void SoRotationXYZ::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 SoNode.

void SoRotationXYZ::getMatrix (SoGetMatrixAction *action) [virtual]

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

void SoRotationXYZ::pick (SoPickAction *action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

void SoRotationXYZ::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual]

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoNode.
