= Release Notes for Rappture 1.2 =

 * New 2D contour/surface (heightmap) viewer. 
   * old surface (heightmap) viewer is replaced by contour/surface viewer.
   * displays [wiki:rp_xml_ele_field <field>] objects with any type of 2D [wiki:rp_xml_ele_mesh <mesh>].
 * [wiki:rp_xml_ele_mesh <mesh>] object upgraded.
   * deprecated [wiki:rp_xml_ele_unirect2d <unirect2d>] and [wiki:rp_xml_ele_cloud <cloud>] objects.  
   * includes cloud, uniform rectilinear grid (like [wiki:rp_xml_ele_mesh <unirect2d>], nonuniform rectilinear grid, curvilinear grid, triangular, and an unstructured grid that may have heterogeneous cell types. Old style '''<node>'''and '''<element>''' format is deprecated.
   * no longer automatically demote 3D data to lower dimensions.  If you want an X-Y plot, use a [wiki:rp_xml_ele_curve <curve>] instead of a 1D mesh (a 3D mesh with no range in the Y and Z axes).
 * [wiki:rp_xml_ele_field <field>] object upgraded.
   * can use legacy VTK file format.
   * can use AVS UCD file format.
 * New isosurface viewer replaces old VTK version.
   * displays [wiki:rp_xml_ele_field <field>] objects with any type of 3D [wiki:rp_xml_ele_mesh <mesh>].
   * fixes zoom/rotation. No gimbal lock.  No initial zoom.
   * axes
   * legend
 * Many improvements for volume viewer.
   * lighting improvements.
