Detailed Description

The SoClipPlaneManip class is used to manipulate clip planes.

jack.png

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.

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).

Since:
TGS Inventor 2.5

Coin 1.0


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  )  [protected]
 

Destructor.


Member Function Documentation

void SoClipPlaneManip::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 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.

See also:
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 fromfc,
SbBool  copyconnections
[protected, virtual]
 

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 subclasses which needs to account for internal data that are not handled automatically.

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
[static, protected]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Called whenever dragger is touched.

void SoClipPlaneManip::fieldSensorCB void *  m,
SoSensor d
[static, protected]
 

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.

void SoClipPlaneManip::transferFieldValues const SoClipPlane from,
SoClipPlane to
[static, protected]
 

Copies field values from one clip plane node to another.
