Interface PointPickSensor

All Superinterfaces:

X3DChildNode, X3DNode, X3DPickSensorNode, X3DSensorNode

All Known Implementing Classes:

PointPickSensor

public interface PointPickSensor
extends X3DPickSensorNode

PointPickSensor tests one or more pickingGeometry points in space as lying inside the provided pickTarget geometry.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. PointPickSensor node tooltip: (X3D version 3.2 or later) [X3DPickSensorNode] PointPickSensor tests one or more pickingGeometry points in space as lying inside the provided pickTarget geometry. For each pickingGeometry PointSet coordinate point that lies inside the pickTarget geometry, a pickedPoint coordinate is returned along with a corresponding pickedGeometry node inside which the point lies.

• Hint: because points represent an infinitely small location in space, sortOrder values CLOSEST and ALL_SORTED are defined to mean ANY and ALL respectively.
• Hint: picking is performed between rendered frames of the event model. An author sets up the picking request in one frame by placing a LinePickSensor in the desired location. At the start of the next frame, any picking intersections are reported by the pick sensor.
• Hint: picking notification is performed at the start of the frame for all enabled pick sensors once all other sensors are processed.
• Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/concepts.html#ExecutionModel
• Warning: order of contained nodes is significant, single pickingGeometry node must precede pickTarget node array.
• Hint: PointSet can be used for pickingGeometry node.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).

getObjectType

String[] getObjectType()

Provide array of String enumeration results with quoted value(s) ["ALL","NONE","TERRAIN",...] from inputOutput MFString field named objectType.

Tooltip: The objectType field specifies a set of labels used in the picking process. Each string specified is treated as an independent label that needs to be matched against the same type in one of the pick sensor instances. Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to intersect a pick sensor with objectType value "GROUND" fails since the objectType values do not match. Example: the special value "ALL" means that each node is available for picking regardless of the type specified by the pick sensor. Example: the special value "NONE" effectively disables all picking for this node and is the equivalent of setting the pickable field of the corresponding PickableGroup to false.

• Hint: authors may define any value for objectType.
• Hint: MFString arrays can have multiple values, so "separate each individual string" "by using quote marks".

Specified by:

getObjectType in interface X3DPickSensorNode

Returns:

value of objectType field

setObjectType

PointPickSensor setObjectType(String[] newValue)

Accessor method to assign String enumeration array (""ALL"" | ""NONE"" | ""TERRAIN"") to inputOutput MFString field named objectType.

Tooltip: The objectType field specifies a set of labels used in the picking process. Each string specified is treated as an independent label that needs to be matched against the same type in one of the pick sensor instances. Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to intersect a pick sensor with objectType value "GROUND" fails since the objectType values do not match. Example: the special value "ALL" means that each node is available for picking regardless of the type specified by the pick sensor. Example: the special value "NONE" effectively disables all picking for this node and is the equivalent of setting the pickable field of the corresponding PickableGroup to false.
