Ice in a nuttshell
----------------------

ICE is a fast OpenGl rendering API for remote sensing images. This small piece
of code decomposes into an OTB/OpenGl only library with an API for simple
rendering of remote sensing images and a GLFW3 example of how to use the API.

---------------------
Installation
----------------------

Dependencies:

- OTB (>= 4.0)
- OpenGl
- GLFW (>= 3.0)

-------------------------
Platform specific issues
-------------------------

OSX (10.9) Mavericks Requires:
XQuartz (http://xquartz.macosforge.org/landing/) because it includes freeGLUT. Therefore
in cmake, the following variables need to point to the correct places:
GLUT_INCLUDE_DIR=/usr/X11R6/include
GLUT_glut_LIBRARY=/usr/X11R6/lib/libglut.dylib

----------------------
Command Line Arguments
----------------------
 
Usage: ./otbIce img1 ... imgN

The authors would like to thank Gabriele Facciolo (CMLA) and the
authors of pvflip (https://github.com/gfacciol/pvflip/) for the seed
discussion about float32 OpenGl textures and OpenGl Shading Language
which greatly contributed to the dawn of Ice.
