      Parameters:
      shadowMapIndex - the index of the shadow map

    • setMaterialParameters

      protected void setMaterialParameters(Material material)
      Description copied from class: AbstractShadowRenderer
      This method is called once per frame and is responsible for setting any material parameters that subclasses may need to set on the post material.
      Specified by:
      setMaterialParameters in class AbstractShadowRenderer
      Parameters:
      material - the material to use for the post shadow pass

    • clearMaterialParameters

      protected void clearMaterialParameters(Material material)
      Description copied from class: AbstractShadowRenderer
      This method is called once per frame and is responsible for clearing any material parameters that subclasses may need to clear on the post material.

      Parameters:
      material - the material that was used for the post shadow pass

    • getLight

      the point light

    • setLight

      public void setLight(PointLight light)
      sets the light to use for casting shadows with this processor
      Parameters:
      light - the point light

    • cloneFields

      public void cloneFields(Cloner cloner, Object original)
      Description copied from interface: JmeCloneable
      Implemented to perform deep cloning for this object, resolving local cloned references using the specified cloner. The object can call cloner.clone(fieldValue) to deep clone any of its fields.

      Note: during normal clone operations the original object will not be needed as the clone has already had all of the fields shallow copied.

      Specified by:
      cloneFields in interface JmeCloneable
      Overrides:
      cloneFields in class AbstractShadowRenderer
      Parameters:
      cloner - The cloner that is performing the cloning operation. The cloneFields method can call back into the cloner to make clones of its subordinate fields.
      original - The original object from which this object was cloned. This is provided for the very rare case that this object needs to refer to its original for some reason. In general, all of the relevant values should have been transferred during the shallow clone, and this object need only clone what it wants.

      Overrides:
      read in class AbstractShadowRenderer
      Parameters:
      im - importer (not null)
      Throws:
      IOException - from the importer

    • write

      public void write(JmeExporter ex) throws IOException
      Description copied from class: AbstractShadowRenderer
