Class SparseFieldPortrayal3D

All Implemented Interfaces:
Portrayal, Portrayal3D
Direct Known Subclasses:
ContinuousPortrayal3D, SparseGridPortrayal3D

public abstract class SparseFieldPortrayal3D extends FieldPortrayal3D
An abstract superclass for all FieldPortrayal3Ds which display SparseFields. This class handles the createModel() and updateModel() methods for you; all you need to implement are the setField(), completedWrapper(), and getLocationOfObjectAsVector3d() methods.

SparseFieldPortrayal3D presently takes the TransformGroups of the models of its children and wraps them into BranchGroups so that they can be removed and added dynamically.

  • Method Details

    • getLocationOfObjectAsVector3d

      public abstract javax.vecmath.Vector3d getLocationOfObjectAsVector3d(Object location, javax.vecmath.Vector3d putInHere)
      Converts a given location (perhaps a Double3D, Double2D, Int3D, or Int2D) into a Vector3d, placing it in the given Vector3d, and returning that Vector3d. Double2D and Int2D should convert to a Vector3d with a zero Z value.
    • createModel

      public javax.media.j3d.TransformGroup createModel()
      Description copied from class: FieldPortrayal3D
      Returns a tree structure of the form InternalTransformGroup[model info].

      ...where InternalTransformGroup is an identity transformgroup whose transform will be modified elsewhere (create it but don't play with it).

      Specified by:
      createModel in class FieldPortrayal3D
    • wrapModelForNewObject

      protected javax.media.j3d.BranchGroup wrapModelForNewObject(Object o, javax.media.j3d.Transform3D localT)
      This function is called from createModel for each object in the field and from the updateModel part of getModel for the new objects.

      In order to dynamically add/remove the subtrees associated with children, this function wraps their TransformGroups into BranchGroups.

    • updateModel

      public void updateModel(javax.media.j3d.TransformGroup globalTG)
      Description copied from class: FieldPortrayal3D
      Returns a tree structure of the form InternalTransformGroup[model info].

      ...where InternalTransformGroup is an identity transformgroup whose transform will be modified elsewhere (don't play with it). By default, this function does nothing. Override it to update the model when it's called.

      Overrides:
      updateModel in class FieldPortrayal3D
