+Morph view
+==========
+
+**Syntax**:(morphview float float float float) For the time selected by the
+next :ref:`usleep <usleep>` or other timing function, the viewpoint is smoothly
+morphed from the current one to that selected by morphview.
+
+Viewport is selected by the center and two radiuses (real and imaginary). See
+:ref:`view <uiview>` for more information.
+
+This function can easily be used for creating zooming/unzooming animations
+using position files. This is an example position file generated by XaoS::
+
+	(initstate)
+	(defaultpalette 0)
+	(formula 'mandel)
+	(view -1.64128273713 -5.50393226816E-05 9.69332308848E-08 9.69332308834E-08)
+
+By replacing the view command with morphview and adding usleep you can create a
+zooming animation::
+
+	(initstate)
+	(defaultpalette 0)
+	(formula 'mandel)
+	(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08 9.69332308834E-08)
+	(usleep 10000000)
+
+**Available as**: command
