Detailed Description

       The SoVRMLBox class is used for representing a 3D box.

       The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC
       14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the
       Consortium:

       Box {
         field    SFVec3f size  2 2 2        # (0, inf)
       }

       The Box node specifies a rectangular parallelepiped box centred at (0, 0, 0) in the local
       coordinate system and aligned with the local coordinate axes. By default, the box measures
       2 units in each dimension, from -1 to +1. The size field specifies the extents of the box
       along the X-, Y-, and Z-axes respectively and each component value shall be greater than
       zero. Figure 6.2 illustrates the Box node.

         Figure 6.2

       Textures are applied individually to each face of the box. On the front (+Z), back (-Z),
       right (+X), and left (-X) faces of the box, when viewed from the outside with the +Y-axis
       up, the texture is mapped onto each face with the same orientation as if the image were
       displayed normally in 2D. On the top face of the box (+Y), when viewed from above and
       looking down the Y-axis toward the origin with the -Z-axis as the view up direction, the
       texture is mapped onto the face with the same orientation as if the image were displayed
       normally in 2D. On the bottom face of the box (-Y), when viewed from below looking up the
       Y-axis toward the origin with the +Z-axis as the view up direction, the texture is mapped
       onto the face with the same orientation as if the image were displayed normally in 2D.
       SoVRMLTextureTransform affects the texture coordinates of the Box. The Box node's geometry
       requires outside faces only. When viewed from the inside the results are undefined.

Member Function Documentation

   SoType SoVRMLBox::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 SoVRMLGeometry.

   const SoFieldData * SoVRMLBox::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.

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

       Reimplemented from SoShape.

   void SoVRMLBox::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 SoVRMLBox::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 SoVRMLBox::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.
