NAME
     distort - real time image distortion demo

SYNOPSIS
     distort [imgfile]

DESCRIPTION
     distort demonstrates how texture mapping can be used to produce real time
     image distortion effects.  This is achieved by mapping a high resolution
     texture onto a large array of polygons.

     The imgfile argument is used to indicate the name of an alternate image
     file.  The default image,
     /usr/demos/General_Demos/distort/data/distort.rgb, is a picture of a dog.

     Use the left mouse button to select one of the following distortion ef-
     fects:

     Ripple
          This effect approximates looking at an image through a thin layer of
          water.  The right mouse button can be used to tap on the water, gen-
          erating ripple patterns.

     Rubber
          The image is mapped onto a mesh of springs which behave like those
          used in the jello demo.  The mesh can be manipulated by holding down
          the right mouse button and dragging.

     Press the ESC key to exit the program.

BUGS
     Requires a hardware texturing or a good imagination.  The source image
     must be square.
