NAME

       SoProfile -

       The SoProfile class is the abstract superclass for profile definitions.

       Node subclasses of SoProfile specifies profiles for extruded 3D text and nurbs surface
       data.

SYNOPSIS

       #include <Inventor/nodes/SoProfile.h>

       Inherits SoNode.

       Inherited by SoLinearProfile, and SoNurbsProfile.

Detailed Description

       The SoProfile class is the abstract superclass for profile definitions.

       Node subclasses of SoProfile specifies profiles for extruded 3D text and nurbs surface
       data.

Member Enumeration Documentation

   enum SoProfile::Profile Enumeration of various choices of how to link together multiple
       profiles.
       Enumerator:

       START_FIRST
              Replace the current profile state set with this profile alone.

       START_NEW
              Append this profile to the state as a new profile.

       ADD_TO_CURRENT
              Append indices of this node to the last profile.

Constructor & Destructor Documentation

   SoProfile::SoProfile (void) [protected] Constructor.
   SoProfile::~SoProfile () [protected, virtual] Destructor.

Member Function Documentation

   void SoProfile::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 SoNode.

       Reimplemented in SoLinearProfile, and SoNurbsProfile.

   void SoProfile::doAction (SoAction *action) [virtual] This function performs the typical
       operation of a node for any action.
       Reimplemented from SoNode.

   void SoProfile::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 SoProfile::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 SoProfile::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 SoProfile::pick (SoPickAction *action) [virtual] Action method for SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

   void SoProfile::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.

   void SoProfile::getTrimCurve (SoState *state, int32_t &numpoints, float *&points, int
       &floatspervec, int32_t &numknots, float *&knotvector) [pure virtual] Return points and
       knotvector of the state.
       Implemented in SoLinearProfile, and SoNurbsProfile.

   void SoProfile::getVertices (SoState *state, int32_t &numvertices, SbVec2f *&vertices) [pure
       virtual] Return vertex set of state.
       Implemented in SoLinearProfile, and SoNurbsProfile.

Member Data Documentation

   SoMFInt32 SoProfile::index Profile coordinate indices.
       These must match what is available from previous SoProfileCoordinate2 and
       SoProfileCoordinate3 nodes in the traversal.

   SoSFEnum SoProfile::linkage How the indices of this profile node should be combined with the
       current profile index set of the traversal state.
       Default value is SoProfile::START_FIRST.
