Detailed Description

The SoClipPlaneManip class is used to manipulate clip planes.

A manipulator is used by replacing the node you want to edit in the graph with the manipulator. Draggers are used to manipulate the node. When manipulation is finished, the node is put back into the graph, replacing the manipulator.

An SoJackDragger is used by instances of this manipulator class as the default dragger when manipulating SoClipPlane nodes. See the documentation of SoJackDragger for details about how to control the manipulator.

An "action shot" of the SoClipPlaneManip:

This manipulator is an extension versus the original SGI Inventor v2.1 API. In addition to being a Coin extension, it is also present in TGS' Inventor implementation (with the same API).

Please note that this manipulator is a bit different than the other manipulators, since it will not automatically scale and translate the dragger to surround the geometry. The setValue() function must be used to initialize the manipulator/dragger. Below you'll find some example code that loads an Inventor file and adds a clip plane manipulator.

#include <Inventor/Qt/viewers/SoQtExaminerViewer.h>
#include <Inventor/SoDB.h>
#include <Inventor/nodes/SoSeparator.h>
#include <Inventor/actions/SoGetBoundingBoxAction.h>
#include <Inventor/SoInput.h>
#include <Inventor/manips/SoClipPlaneManip.h>

// *************************************************************************

SoQtExaminerViewer * ex = new SoQtExaminerViewer( window );
ex->setBackgroundColor(SbColor(0.1f, 0.3f, 0.5f));
SoInput input;
SbBool ok = input.openFile(argv[1]);
if (!ok) {
fprintf(stderr,"Unable to open file.\n");
return -1;
}
SoSeparator * root = SoDB::readAll(&input);
if (!root) {
fprintf(stderr,"Unable to read file.\n");
return -1;
}
root->ref();
SoGetBoundingBoxAction ba(ex->getViewportRegion());
ba.apply(root);
SbBox3f box = ba.getBoundingBox();
manip->setValue(box, SbVec3f(1.0f, 0.0f, 0.0f), 1.02f);

Constructor & Destructor Documentation

SoClipPlaneManip::SoClipPlaneManip ( void  )

An SoJackDragger is set up here as the internal dragger used for manipulation of an SoClipPlane node.

SoClipPlaneManip::~SoClipPlaneManip ( void  )
protectedvirtual

Destructor.

Member Function Documentation

SoType SoClipPlaneManip::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 SoClipPlane.

const SoFieldData * SoClipPlaneManip::getFieldData ( void  ) const
protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoClipPlane.

SoDragger * SoClipPlaneManip::getDragger ( void  )

Returns pointer to dragger used for interaction.

void SoClipPlaneManip::setValue ( const SbBox3f box,
const SbVec3f planenormal,
float  draggerscalefactor 
)

Sets the clip plane based on the center of box and normal. The size of box is used as a scale factor to the dragger, multiplied with draggerscalefactor.

SbBool SoClipPlaneManip::replaceNode ( SoPath path)

Replaces the node specified by path with this manipulator. The manipulator will copy the field data from the node, to make it affect the state in the same way as the node.

SbBool SoClipPlaneManip::replaceManip ( SoPath path,
SoClipPlane newone 
) const

Replaces this manipulator from the position specified by path with newnode. If newnode is NULL, an SoClipPlane will be created for you.

void SoClipPlaneManip::doAction ( SoAction action)
virtual

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

Reimplemented from SoClipPlane.

void SoClipPlaneManip::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 SoClipPlane.

void SoClipPlaneManip::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 SoClipPlane.

void SoClipPlaneManip::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 SoClipPlaneManip::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 SoClipPlaneManip::handleEvent ( SoHandleEventAction action)
virtual

Action method for SoHandleEventAction.

Inspects the event data from action, and processes it if it is something which this node should react to.

Nodes influencing relevant state variables for how event handling is done also overrides this method.

Reimplemented from SoNode.

void SoClipPlaneManip::pick ( SoPickAction action)
virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoClipPlane.

void SoClipPlaneManip::search ( SoSearchAction action)
virtual

Action method for SoSearchAction.

Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction – if any of the requested criteria is a miss, the search is not deemed successful for the node.

SoSearchAction

Reimplemented from SoNode.

SoChildList * SoClipPlaneManip::getChildren ( void  ) const
virtual

Returns the children of this node.

Reimplemented from SoNode.

void SoClipPlaneManip::setDragger ( SoDragger newdragger)
protected

Sets a dragger to use for this manipulator. The default dragger is an SoJackDragger.

void SoClipPlaneManip::copyContents ( const SoFieldContainer from,
SbBool  copyconnections 
)
protectedvirtual

Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is FALSE.

This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which needs to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:

void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
SbBool copyconnections)
{
// let parent superclasses do their thing (copy fields, copy
// instance name, etc etc)
SoNode::copyContents(from, copyconnections);
// [..then copy internal data..]
}

Reimplemented from SoNode.

void SoClipPlaneManip::valueChangedCB ( void *  m,
SoDragger dragger 
)

void SoClipPlaneManip::fieldSensorCB ( void *  m,

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Called whenever one of the fields changes value.

)

Copies field values from one clip plane node to another.
