pAth Plot

Check "plot" to draw V(t) values at the blue circle position. Press mouse button to move the circle. In 3 seconds the script begins to plot the path of the spiral wave tip (h-gate tip is traced). Use Alt- r, s, p, a keys to control the script.

On 2D plane V values are displayed by the red color. 4 xs 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.
