public class PolylineEmitter
extends X3DConcreteNode
implements PolylineEmitter
PolylineEmitter emits particles along a single polyline.

X3D node tooltip: (X3D version 3.2 or later) [X3DParticleEmitterNode] PolylineEmitter emits particles along a single polyline. The coordinates for the line along which particles should be randomly generated are taken from a combination of the coord and coordIndex fields. The starting point for generating particles is randomly distributed along this line and given the initial speed and direction.
  • Hint: if no coordinates are available, PolylineEmitter acts like a point source located at local origin.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

      • Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
      • Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
      • Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

      • Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
      • Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.


      Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.

      Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

      Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
      Specified by:
      setUSE in class X3DConcreteNode
      Parameters:
      newValue - is new value for the USE field.
