NAME

       SoCube -

       The SoCube class is for rendering cubes.

       Insert a cube shape into the scenegraph. The cube is rendered with the current material,
       texture and drawstyle settings (if any, otherwise the default settings are used).

Detailed Description

       The SoCube class is for rendering cubes.

       Insert a cube shape into the scenegraph. The cube is rendered with the current material,
       texture and drawstyle settings (if any, otherwise the default settings are used).

       (Strictly speaking, as you can have different width, height and depth values for the
       'cube', instances of this class actually represents boxes.)

       The SoCube node class is provided as a convenient abstraction for the application
       programmer to use 'complex' shapes of this type without having to do the calculation and
       book-keeping of the polygon sides and other low-level programming herself.

       FILE FORMAT/DEFAULTS:

       Cube {
           width 2
           height 2
           depth 2
       }

Member Function Documentation

   SoType SoCube::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 SoShape.

   const SoFieldData * SoCube::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 SoShape.

   void SoCube::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.

   void SoCube::rayPick (SoRayPickAction *action) [virtual]
       Calculates picked point based on primitives generated by subclasses.

       Reimplemented from SoShape.

   void SoCube::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 SoShape.

   void SoCube::generatePrimitives (SoAction *action) [protected],  [virtual]
       The method implements action behavior for shape nodes for SoCallbackAction. It is invoked
       from SoShape::callback(). (Subclasses should not override SoNode::callback().)

       The subclass implementations uses the convenience methods SoShape::beginShape(),
       SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the
       primitives making up the shape back to the caller.

       Implements SoShape.

   void SoCube::computeBBox (SoAction *action, SbBox3f &box, SbVec3f &center) [protected],
       [virtual]
       Implemented by SoShape subclasses to let the SoShape superclass know the exact size and
       weighted center point of the shape's bounding box.

       The bounding box and center point should be calculated and returned in the local
       coordinate system.

       The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is
       invoked from SoShape::getBoundingBox(). (Subclasses should not override
       SoNode::getBoundingBox().)

       The box parameter sent in is guaranteed to be an empty box, while center is undefined upon
       function entry.

       Implements SoShape.
