caustic_opengl

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 )
y(I) = sin ( B * 2 * i * pi / Q )

Usage:

caustic_opengl q p a b

• q is the number of points to plot;
• p is the point to which point 0 is connected.
• a defines x(i)=cos(a*2*pi*i/q);
b defines y(i)=sin(b*2*pi*i/q).
