Visualizing Gravity: Fieldlines and Equipotentials
The sample program plots the field in the vicinity of identical spheres placed at the vertices of an equilateral triangle. We have the equations needed to calculate the direction of the field at any arbitrary point, so all we need is a plan for making up curves from line segments.

Discussion for Visualizing Gravity: Fieldlines and Equipotentials

Simple graphical display of equipotential lines. The same effect can be displayed in a textbook just as easily. Of little use.
The firt applet did not work. The second applet has no interactivity. All user can do is push the "Plot" button, which generates the plot. Plot erases if moved off-screen, which can be very annoying since the plot then has to be regenerated, which takes considerable time.
