    abstract     = "Convolution of a {2D} {RGB} image with an {RGB} filter. The filter
is generated procedurally by a shader and the convolution is
computed using the {FFT} on the {GPU}.

Usage: Provide image as command line argument, 
press <SPACE> to switch between image and filtered image.

Building: Build the {SOIL} project first, then the convolution project.

Dependencies: {GLUT,} {GLEW}.

This demo includes the following software packages:
{SOIL,} gpu\_convolution, Timer (partly)

{SOIL} is courtesy of Jonathan Dummer, see disclamers in 
the files of the included {SOIL} project.

Included image was rendered using standard path tracing by Jeppe Revall Frisvad, August 2009.
