VecFieldLIC

VecFieldLIC visualizes 2D autonomous dynamical systems by means of the Line Integral Convolution (LIC) technique introduced by Cabral and Leedom in 1993.

A 2D autonomous dynamical system is defined by two coupled first-order differential equations dx/dt = P(x,y) and dy/dt = Q(x,y) with P and Q being two arbitrary C^1-differentiable functions of x and y.

These two functions can consist of all mathematical functions available from the OpenGL ES Shading Language.

Note that you have to insert numbers as floats, e.g. "2" should read "2.0".
