### OpenCL RayTraced Quaternion Julia-Set Example ###

===========================================================================

DESCRIPTION:

This example shows how to use OpenCL to raytrace a 4d quaternion Julia-Set 

fractal and intermix the results of a compute kernel with OpenGL for rendering.

For theory and information regarding 4d quaternion julia-sets consult the following:

http://local.wasp.uwa.edu.au/~pbourke/fractals/quatjulia/

http://www.evl.uic.edu/files/pdf/Sandin.RayTracerJuliaSetsbw.pdf

http://www.cs.caltech.edu/~keenan/project_qjulia.html

Note that the .cl compute kernel file(s) are loaded and compiled at

runtime.  The example source assumes that these files are in the same 

path as the built executable.

For simplicity, this example is intended to be run from the command line.

If run from within XCode, open the Run Log (Command-Shift-R) to see the 

output.  Alternatively, run the applications from within a Terminal.app 

session to launch from the command line.
