Spiral tip dynamics in the Noble model

Tip Plot

In 3 seconds the script begins to plot the path of the spiral wave tip. Check "plot" to draw V(t) values at the blue circle position. Press mouse button to move the circle. Use Alt- r, s, p, t keys to control the script (my Asus 1215B touchpad is a little buggy :)

On 2D plane V values are displayed by the red color. 2 x values are displayed by the green color. This script uses simple explicit algorithm and 512x512 float32 textures with the Neumann (CLAMP_TO_EDGE) boundary conditions. It makes 2 it time steps per frame. Note that gl.readPixels function is rather slow.
