In a previous lesson, you learned how to draw
lines in 2D graphics. In this mode, you used

`line(x1,y1,x2,y2)`

to draw
a line between the points $(x_1,y_1)$ and $(x_2,y_2)$.
In this lesson, we introduce a 3D line drawing function, called `line3d`

, that'll
draw a line between two points in 3D space, $(x_1,y_1,z_1)$ and $(x_2,y_2,z_2)$.

line3d(x1,y1,z1,x2,y2,z2,color,thickness)

Move the mouse over a dotted box for more information.

You can find a list of color codes here.
The 3D drawing area will appear under your code-editor. You might have to scroll down to see it.

Type your code here:
