Traditional Logo had new users build a house as an introduction, but due to turtleSpaces’ 3D nature, starfields are much more impressive, so we’ll start there.
Click and drag the window above to see all the stars!
Cool huh? First, we’re going to create this simple starfield that wraps around the camera position.
We’ll start by creating the procedure:
TO stars
END
Then we’ll add in some setup stuff:
In this second part of our introduction to turtleSpaces Logo, we’re going to take the stars we made in the first part, and create a ‘rolling’ starfield we are going to move through using the camera turtle, to create a Star Trek-style warp effect.

To create this effect, the drawing turtle, Myrtle, is going to create stars deep into the space. The camera turtle, Snappy, will move forward (the camera turtle points into the space, towards Myrtle, by default) following Myrtle as she moves deeper, creating stars.
