   .. js:class:: CuttingPlane

      Specification of a cutting plane (both parameters and attributes) in a ``RemoteModel``.

      Use this object to control the position, settings and visual attributes of a cutting plane. The 
      position of the cutting plane is defined with ``point`` and ``normal``. You can map a 
      scalar result onto the cutting plane with ``mapScalarResultId``, and show vectors sampled in a regular 
      grid with ``mapVectorResultId``. The spacing of this regular grid is defined with ``vectorGridSpacing``.

      You can specify whether to clip the model in the cutting plane's plane with ``clipping``, show the 
      intersected element mesh with ``showElementMesh`` and set its ``opacity``.

      Please note that cutting planes are more that just geometric clipping planes. They intersect the volume
      elements and produce a surface onto which results can be mapped.  
 
      To create a cutting plane, use ``RemoteModel.addCuttingPlane``.

      **Example:** Create two cutting planes:


      .. code-block:: javascript

         var modelDir = myModel.modelDirectory;

         // Find basis for position and map scalar result
         var bb = myModel.getBoundingBox();
         var halfExtent = bb.getExtent().x/2;
         var mapScalarId = -1;
    
         if (modelDir.scalarResultArray.length > 0) {
             mapScalarId = modelDir.scalarResultArray[0].id;
         }

         // Create plane 1
         var plane1 = myModel.addCuttingPlane();
         plane1.point = cee.Vec3.add(bb.getCenter(), new cee.Vec3(0.5*halfExtent, 0, 0));
         plane1.normal = new cee.Vec3(1,0,0);
         plane1.mapScalarResultId = mapScalarId;

         // Create plane 2
         var plane2 = myModel.addCuttingPlane();
         plane2.point = bb.getCenter();
         plane2.point = cee.Vec3.sub(bb.getCenter(), new cee.Vec3(0.5*halfExtent, 0, 0));
         plane2.normal = new cee.Vec3(1,0,0);
         plane2.mapScalarResultId = mapScalarId;
         plane2.showElementMesh = true;

         // Set model to outline to show the cutting planes
         myModel.setDrawStyleAllParts(cee.ug.DrawStyle.OUTLINE);

      :rtype: void



.. container:: ts-api-section

   .. js:function:: CuttingPlane.computeFromVisibleParts()



      If set to true, the cutting plane will be computed from only the visible parts. Any part that
      is not visible will not contribute to the cutting plane.

      Specify if the cutting plane should show a crinkle cut surface.

      If enabled, the cutting plane surface will be the combined surface of all elements intersected
      by the cutting plane. So the cutting plane will show the tesselation of all intersected elements.

      This is useful for inspecting and visualizing the mesh of a volume element model.

.. rst-class:: ts-api-section

setScalarFilteringVisibleRange
------------------------------

.. js:method:: CuttingPlane.setScalarFilteringVisibleRange( resultId, min, max)

   :param resultId: The id for the result to which this filter should be applied.
   :type resultId: number
   :param min: The minimum scalar value for filtering. Areas with scalar values below this threshold will be set invisible.
   :type min: number
   :param max: The maximum scalar value for filtering. Areas with scalar values above this threshold will be set invisible.
   :type max: number


   Sets the scalar filtering visibility range for cutting plane 

   Specify a filter for a cutting plane by defining a specific result id (resultId) and a scalar 
   range from minimum to maximum.
   The filter allows you to control the visibility of areas on the cutting plane based on scalar values, 
   making areas outside the specified range invisible.

   A common use case for this functionality is to restrict the visibility of a cutting plane to a 
   specific isovolume. By configuring the cutting plane filter with the same result id and scalar range 
   as the isovolume, you can ensure that the cutting plane surface is only visible within the isovolume.

   For a visual representation and example scenarios regarding isovolumes and cutting planes with and 
   without scalar filtering, please refer to the images below.
