Constructor Details

OGLPointPickSensor

public OGLPointPickSensor()

Construct a new time sensor object

OGLPointPickSensor

public OGLPointPickSensor(VRMLNodeType node)

Construct a new instance of this node based on the details from the given node. If the node is not the same type, an exception will be thrown.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not the same type

Method Details

setParentGroup

public void setParentGroup(org.j3d.aviatrix3d.Group group)

Set a parent to this sensor. Really doesn't matter if one overwrites another. The parent should only be needed to work out where the sensor is in world space coordinates, since the sensor itself never has an underlying scene graph object representation. In addition, if a picking sensor has more than one parent in the transformation hierarchy, the results are entirely bogus anyway.

Specified by:

setParentGroup in interface OGLPickingSensorNodeType

Parameters:

group - The parent group of this sensor

getParentGroup

public org.j3d.aviatrix3d.Group getParentGroup()

Fetch the parent grouping node from this sensor so that we can track back up the stack for the world transformation.

Specified by:

getParentGroup in interface OGLPickingSensorNodeType

Returns:

The currently set parent transform

getTargetMapping

public Map<org.j3d.aviatrix3d.picking.PickableObject,VRMLNode> getTargetMapping()

Get the set of target PickableObjects that this sensor manages. If there are none, return an empty set.

Specified by:

getTargetMapping in interface OGLPickingSensorNodeType

Returns:

A set of OGL nodes mapped to their VRML wrapper

getTargetObjects

public org.j3d.aviatrix3d.picking.PickableObject[] getTargetObjects()

Get the collection of ra target PickableObjects that this sensor manages.

Specified by:

getTargetObjects in interface OGLPickingSensorNodeType

Returns:

A set of OGL nodes for pick testing

setTypeConvertor

public void setTypeConvertor(OGLPickingFlagConvertor conv)

Set the flag convertor that will be used to map the object type strings to the internal pick masks. A value of null will clear the current instance.

Specified by:

setTypeConvertor in interface OGLPickingSensorNodeType

Parameters:

conv - The convertor instance to use, or null

getPickMask

public int getPickMask()

Get the int mask used to perform picking with. This is the mask generated after passing the collection of pick string flags through the picking flag convertor.

Specified by:

getPickMask in interface OGLPickingSensorNodeType

Returns:

The pick bitmask to use

setObjectType

public void setObjectType(String[] types,
 int numValid)

Set the list of picking targets that this object corresponds to. These can be an array of strings.

Specified by:

setObjectType in interface VRMLPickingSensorNodeType

Overrides:

setObjectType in class BasePickingNode

Parameters:

types - The list of object type strings to use

numValid - The number of valid values to read from the array

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Get the Java3D scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OGL representation.

updateChildren

protected void updateChildren(VRMLNodeType[] targets,
 int numValid)

Update the child list with the new nodes. This is called after all the basic filtering has been complete and may be overridden by derived classes if needed. The default implementation is empty.

Overrides:

updateChildren in class BasePickingNode

Parameters:

targets - The list of current children

numValid - The number of valid children to check
