OpenGL

1. Simple 2D example 
Compile and run the examples here:
http://www.cs.utk.edu/~dbanks/courses/2009.3/src/square/

Modify the code to make multiple objects move around
the screen.


2.  Simple 3D example 
Compile and run the examples here:
http://www.cs.utk.edu/~dbanks/courses/2009.3/src/surface/

Modify the surface to "morph" over time between two shapes,
each defined by coefficients for a quadratic graph

  ( x, y,  f(x,y) )

where 

  f(x,y) =  a00 + a01 x + a10 y + a02 x^2 + a11 xy + a20 y^2

The coefficients are stored in an external text file.
Compute the normal at each vertex.
The vertices fill a grid as shown below.
