The main purpose of the VPython programming language is to create 3D simulation with creating the 3D objects. To achieve this purpose, VPython already contains a number of built-in 3-dimensional objects, and these objects are displayed in a 3D graphics module called Visual. Familiarizing with these objects is important for lab coding.

Before start coding, make sure to have

===Example Code of Each Objects ===
Arrow
a = arrow(pos=(0,2,1),axis=(5,0,0), color = color.red)

Box
b = box(pos=(0,0,0),length=3, height=3, width=3, color = color.orange)

Cone
c = cone(pos=(0,0,0),axis=vector(2,0,0), radius=1, color = color.yellow)

Curve
c = curve(pos=[(-1,-1,0), (1,-1,0)], color = color.green) #create object
c.append(pos=(3,2,-2)) #append next position vector
c.append(pos=(4,1,2))

Cylinder
c = cylinder(pos=vector(0,2,1), axis=vector(5,0,0), radius=1, color=color.cyan)

Ellipsoid
e = ellipsoid(pos=vector(0,0,0), length=3, height=5, width=7, color=color.blue)

Extrusion
#define polygons first
tri = Polygon( [(-2,0), (0,4), (2,0)] )
circ = shapes.circle(pos=(0,1.5), radius=0.8)
straight = [(0,0,0),(0,0,-4)]
#create extrusion
e = extrusion(pos=straight, shape=tri-circ, color=color.magenta)

Helix
h = helix(pos=vector(0,2,1), axis=vector(5,0,0), radius=0.5, color=(0.96,0.73,0.14))

Label
l = label(pos=vector(0,0.25,0), text='This is a Label', xoffset=20, yoffset=50, space=30, height=16, border=4,font='sans')

Points
p = points(pos=[vector(-1,0,0), vector(1,0,0)], radius=50, color=(1,1,.94))

Pyramid
p = pyramid(pos=vector(5,2,0), size=vector(3,3,2), color=(0.82, 0.41, 0.12))

Ring
r = ring(pos=vector(1,1,1), axis=vector(0,1,0),radius=0.5, thickness=0.1, color=(0.14, 1, 0.83))

Sphere
s = sphere(pos=vector(1,1,1), radius=5, color=(0.5, 1, 0.5))

Text
t = text(text='This is \ntext', #use \n for changing line
align='center', color=(0.94, 0.90, 0.55))

==Commonly Used Objects==
The following objects are often used in class lab.

===Sphere===
The sphere object can be used to represent a wide variety of things, but it is mostly used to represent spherical objects such as planets or particles such as protons and electrons. Two things must be set; the position (vector), and the radius (numerical value).

===Arrow===
The arrow is perhaps the most important object for physics simulation. It can be used to represent various forces as well as visualizing vectors. To create an arrow, the position (vector), axis (vector), and the shaftwidth (a numerical value) must be set.

===Curve===
The curve is often used to create a trail mark that represents a path that the object has moved, and it is also frequently used to create graphs. To create a curve, put the initial position vector of the curve, and append the next positions while updating the position in the while loop.

==Application==
Following code is an example usage and application of object creation for lab simulations.

## objects
ceiling = box(pos=vector(0,0,0), size = vector(0.2, 0.01, 0.2)) # origin is at ceiling
ball = sphere(pos=vector(.1,-.2,.3), radius=0.025, color=color.orange) # note: spring initially compressed
spring = helix(pos=ceiling.pos, color=color.cyan, thickness=.003, coils=40, radius=0.015)
parrow = arrow(color=color.magenta, pos=ball.pos, axis=vector(0,0,0))
farrow = arrow(color=color.red, pos=ball.pos, axis=vector(0,0,0))
trail = curve(color=ball.color)

#graphs
Kgraph=gcurve(color=color.red)
Ugraph=gcurve(color=color.cyan)
KUgraph=gcurve(color=color.yellow)

#graph updates are done in the while loop.

Pyramid
p = pyramid(pos=vector(5,2,0), size=vector(3,3,2), color=(0.82, 0.41, 0.12))

Ring
r = ring(pos=vector(1,1,1), axis=vector(0,1,0),radius=0.5, thickness=0.1, color=(0.14, 1, 0.83))

Sphere
s = sphere(pos=vector(1,1,1), radius=5, color=(0.5, 1, 0.5))

Text
t = text(text='This is \ntext', #use \n for changing line

==Commonly Used Objects==
The following objects are often used in class lab.

===Sphere===
The sphere object can be used to represent a wide variety of things, but it is mostly used to represent spherical objects such as planets or particles such as protons and electrons. Two things must be set; the position (vector), and the radius (numerical value).

===Arrow===
The arrow is perhaps the most important object for physics simulation. It can be used to represent various forces as well as visualizing vectors. To create an arrow, the position (vector), axis (vector), and the shaftwidth (a numerical value) must be set.

===Curve===
The curve is often used to create a trail mark that represents a path that the object has moved, and it is also frequently used to create graphs. To create a curve, put the initial position vector of the curve, and append the next positions while updating the position in the while loop.

'''Claimed by Do Won Kim (Fall 2017) (In Progress)'''

The main purpose of the VPython programming language is to create 3D simulation with creating the 3D objects. To achieve this purpose, VPython already contains a number of built-in 3-dimensional objects, and these objects are displayed in a 3D graphics module called Visual. Familiarizing with these objects is important for lab coding.

Before start coding, make sure to have

from __future__ import division
from visual import *

on the top of your script.

This document is written based on VPython 7.

==Commonly Used Objects==
The following objects are often used in class lab.

===Sphere===
The sphere object can be used to represent a wide variety of things, but perhaps the most important for use in Physics 2 is point charges and protons/electrons. Two things must be set; the position, a vector; and the radius, a numerical value.

===Arrow===
The arrow is perhaps the most important object for Physics 2. It can be used to represent Electric and magnetic fields as well as visualizing vectors. To create an arrow the position (a vector), axis (a vector), and the shaftwidth (a numerical value) must be set.

==Object Uses==

===Examples of Simple Objects===
<code>
:sphere1 = sphere(pos=vector(4,8,15), radius=16)
:
:arrow1 = arrow(pos=vector(4,8,15), axis=vector(16,23,42)
:
:helix1 = helix(pos=vector(4,8,15), axis=vector(16,23,42) radius=.23)</code>

===Modeling Fields===
<code>
:from visual import *
:mzofp = 1e-7
:oofpez = 9e9
:qe = 1.6e-19
:
:proton = sphere(pos=vector(3e-10,0,0), radius=1e-11, color=color.red)
:velocity = vector(-5.2e4,0,0) #The proton's velocity
:r_obs = vector(0,8e-11,0) #The observation location
:deltat = 1e-19 #Timestep
:
:while proton.x < 5e-10:
:: r = r_obs - proton.pos
:: rhat = r/mag(r)
:: Efield = oofpez*qe*rhat/(mag(r)**2)
:: Bfield = mzofp*qe*cross(velocity,that)/(mag(r)**2)</code>

'''Claimed by Do Won Kim (Fall 2017) (In Progress)'''

The main purpose of the VPython programming language is to create 3D simulation with creating the 3D objects. To achieve this purpose, VPython already contains a number of built-in 3-dimensional objects, and these objects are displayed in a 3D graphics module called Visual. Familiarizing with these objects is important for lab coding.

Before start coding, make sure to have

from __future__ import division
from visual import *

on the top of your script.

This document is written based on VPython 7.

'''Claimed by Do Won Kim (Fall 2017)'''

The VPython programming language contains a number of 3-dimensional objects that can be displayed in a 3D graphics module called Visual.

==Overview==

VPython is packaged with a variety of 3-Dimensional objects. These objects include:
#[http://www.glowscript.org/docs/VPythonDocs/arrow.html Arrow]
#[http://www.glowscript.org/docs/VPythonDocs/box.html Box]
#[http://www.glowscript.org/docs/VPythonDocs/cone.html Cone]

#[http://www.glowscript.org/docs/VPythonDocs/sphere.html Sphere]
#[http://www.glowscript.org/docs/VPythonDocs/text.html Text]
The ease with which these objects can be manipulated using python makes them popular in physics classes.

==Important Objects==
The following objects appear often in Physics 2.

===Sphere===
The sphere object can be used to represent a wide variety of things, but perhaps the most important for use in Physics 2 is point charges and protons/electrons. Two things must be set; the position, a vector; and the radius, a numerical value.

===Arrow===
The arrow is perhaps the most important object for Physics 2. It can be used to represent Electric and magnetic fields as well as visualizing vectors. To create an arrow the position (a vector), axis (a vector), and the shaftwidth (a numerical value) must be set.

==Object Uses==

===Examples of Simple Objects===
<code>
:sphere1 = sphere(pos=vector(4,8,15), radius=16)
:
:arrow1 = arrow(pos=vector(4,8,15), axis=vector(16,23,42)
:
:helix1 = helix(pos=vector(4,8,15), axis=vector(16,23,42) radius=.23)</code>

===Modeling Fields===
<code>
:from visual import *
:mzofp = 1e-7
:oofpez = 9e9
:qe = 1.6e-19
:
:proton = sphere(pos=vector(3e-10,0,0), radius=1e-11, color=color.red)
:velocity = vector(-5.2e4,0,0) #The proton's velocity
:r_obs = vector(0,8e-11,0) #The observation location
:deltat = 1e-19 #Timestep
:
:while proton.x < 5e-10:
:: r = r_obs - proton.pos
:: rhat = r/mag(r)
:: Efield = oofpez*qe*rhat/(mag(r)**2)
:: Bfield = mzofp*qe*cross(velocity,that)/(mag(r)**2)</code>
