GlowScript

Claimed by Hwuiwon Kim (Spring 2019)

GlowScript IDE is an environment where people can create 3D animations and share them on web.
Scripts can be written in VPython.

Commands

Header

---

GlowScript 2.7 VPython is required in header to run Vpython.
GlowScript 2.7 JavaScript is required in header to run javascript.

Initialize new Variables

---

Use var and assign values.

var x, y
x = 2
y = 3

There is no need to put semi-colon in the end of a line.

3D Objects

---

Arrow

newArrow = arrow(pos=vec(x0, y0, z0), shaftwidth=1, axis_and_length=vec(x1, y1, z1))

This creates arrow that starts at point <x0, y0, z0> that points <x1, y1, z1>

Box

newBox = box(pos=vec(x0, y0, z0), size=vec(L, H, W))

This creates a box with a center <x0, y0, z0> and with size <L, H, W>

Sphere

newSphere = sphere(pos=vec(x0, y0, z0), size=vec(x1, y1, z1) )

This creates a box with a center <x0, y0, z0> and with size <x1, y1, z1>

Customizing Objects

Color
There are 10 default colors that can be used.

color.red, color.yellow, color.green, color.orange
color.blue, color.cyan, color.magenta, color.purple
color.black, color.white

Colors can be customized by user by using following code.

vec(1, 0.5, 0.3)

In this case, R is 1, G = 0.7, and B = 0.2, which has color of pastel orange.

Animation Speed

This line will halt each computations to have interval of 1.0/50.0 second.
