When it opens, hit Play on the Sequencer and wait for the first set of images to be calculated (Loop is already on, as is "Palindrome" mode which rocks back and forth from begin frame to end frame).

Here is yet another way to display the water molecule data. An isosurface is calculated, but then we apply a ShowPositions module which displays only the locations of the vertices of the surface itself. Through the center is a MapToPlane that has been colored. (Hit Stop at any time on the Sequence Control.)

Take a look at the program itself (Windows: Open Visual Program Editor). See how much sense you can make of the program by starting at Import and tracing the lines down through the modules to Display. Display is another kind of "image" window but it offers no interactive user controls like those we have in the Image window.

You'll want to stretch the Program Editor window so you can see the whole program at once. I don't expect you to understand all that's going on, but this is a somewhat more sophisticated program than we just viewed, so it's useful to see how a simple program can be elaborated to provide more features. If you like, drag the modules around on the "canvas" and watch how the lines stay attached. It is possible, with some fiddling, to make a net either very readable by lining up operations more or less vertically, or to generate glorious spaghetti code by tangling the wires up. Even if the wires are impossible to follow, the logic of their connectivity is preserved (at least to DX). But since we will have to make and edit and maintain these programs, try to get in the habit of organizing module locations as neatly as possible (it's never possible to get things perfect). Nets can be quite readable if you do this.

If you accidentally disconnect a wire while you are dragging things around, quit without saving, and reopen the net. We'll soon learn how to connect and disconnect wires intentionally.

If you are particularly observant, you'll be able to tell me which module receives and groups more than one discrete object for display in the same Display window. Answer

Quit this program.
