Short Description of Topic

The Main Idea

The main idea of this page is to serve as an aid for future physics students in writing python code during lab.

Starting Out

These are the first two lines of code that you should put into every one of the codes we have in this class:

from __future__ import division

from visual import *

Making Basic Objects

Vectors

vector = vector(x,y,z)

Spheres

sphere = sphere(pos=POS, color=color.COLOR, radius=RADIUS ) POS: a vector giving the sphere location COLOR: Options can be found on http://matplotlib.org/examples/color/named_colors.html RADIUS: The radius of the sphere (usually given by the lab instructions)

Arrows

arrow = arrow(pos=POS, axis=AXIS color=color.COLOR) POS: where the head of the arrow is to be placed AXIS: the line that we want the axis to go along (generally some position - * position) COLOR: Options can be found on http://matplotlib.org/examples/color/named_colors.html

Connectedness

VPython is an important tool in PHYS 2211 and PHYS 2212 because it is able to take a very abstract concept and give a visual explanation to the student.
