This is a beginner guide to VPython for people who have no or little coding experience and are concerned about the coding part of the course.
The Main Idea
State, in your own words, the main idea for this topic VPython is a programming language with graphics module that is useful for simulation and animation of physical processes. In other words, it allows to see what would happen to the motion of the Earth if it crashed with the giant asteroid just by writing several lines of code insted of creating a doomsday!
Installation
VPython is available for Windows, Machintosh and Linux.
A Computational Model
How do we visualize or predict using this topic. Consider embedding some vpython code here Teach hands-on with GlowScript
Basics
Befor writing your VPython program be sure to include those lines
from __future__ import division
from visual import *
These lines are needed to invoke the visual module and to make sure that when you calculate 3/4 you get 0.75 and not 0.
Creating vectors
You can create a vector v in Vpython by doing v = vector(x, y, z)
Creating objects
You will be creating several 3D shapes to represent objects and particles in your simulations. You will usually name your objects in order to access or modify their information (e.g. update the position). You can access the attributes of the object you created just by doing object.attribute (e.g. electron.pos). Here is the code sample for the most common ones:
Sphere: ball = sphere(pos=(x,y,z,), radius=r, color = color.your_color)
Arrow: someArrow = arrow(pos=(x1,y1,z1), axis=(x2,y2,z2), color = color.your_color)
Middling
Difficult
Connectedness
- How is this topic connected to something that you are interested in?
- How is it connected to your major?
- Is there an interesting industrial application?
History
Put this idea in historical context. Give the reader the Who, What, When, Where, and Why.
