SYNOPSIS
========

.. parsed-literal:: 
   :class: codefhead

   **glViewer**
   [**-d** *isolation level*]
   [**-c** *animation loops*]
   [**-f**]
   [**-axis**]
   *objfile(s)*

DESCRIPTION
===========

``glViewer`` is a stand-alone application that showcases the application of 
uniform and feature adaptive subdivision schemes to a collection of geometric
shapes. Multiple controls are available to experiment with the algorithms.

OPTIONS
=======

**-d** *isolation level*
  Select the desired isolation level of adaptive feature isolation. This can be 
  useful when trying to load large pieces of geometry.

**-c** *animation frequency*
  Number of repetitions of the animation loop (default=0 is infinite)

**-f**
  Launches the application in full-screen mode (if is supported by GLFW on the
  OS)

**-axis**
  Swap Y-up / Z-up axis when loading obj files

*objfile(s)*
  A sequence of obj files used as an animation loop (the topology has to match
  the data contained in all the ptex files !)
