SYNOPSIS
========

.. parsed-literal:: 
   :class: codefhead

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

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

``glBatchViewer`` is a stand-alone application that showcases the primitive 
batching capabilities of the OpenSubdiv API. Batching is an optimization that
enables the merging together of the data tables of many primitives in order to
reduce the number of GPU calls.

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 animtion loop (default=0 is infinite)

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

Keyboard Controls
=================

   .. code:: c++
   
      . ,      : increase / decrease the number of animated primitives
      i, o     : add / remove primitives
