caustic_opengl, a C++ code which computes a caustic curve based on user input, and uses OpenGL to display it.
The user specifies a value Q, the number of points, a value P which controls which points will be connected, and values A and B which determine the curve on which the points lie.
The program then plots Q points along the curve
x(I) = cos ( A * 2 * i * pi / Q )and connects each point I to point I+P, using modular arithmetic where necessary.
y(I) = sin ( B * 2 * i * pi / Q )
