- Desert Mountain Lake — An Introduction to Fill
In a recent update to turtleSpaces, we added the ability to create arbitrary shapes, using the beginfill and endfill primitives.
To create a shape, you simply declare beginfill, draw out its borders and then declare endfill. If the lines do not cross each other, then the shape should be created.

- Logo and the Language Microworld
Logo isn’t just all about the turtles! When Logo was first being developed, there were no graphical displays — output was simple text on teletypes, which printed out interactions with the computer on paper.

- A Starry turtleSpaces Logo Introduction Part Three: Starwarp Improvements
In the previous episode, we created a progressively-generated starfield we moved through with the camera turtle, creating a cool flying-through-space effect.
But it has a few issues we should address. Firstly, it is possible for a star to end up flying through the windscreen of our spaceship! Which is cool, but looks a bit strange. Second, ...
- A Starry turtleSpaces Logo Introduction Part Two: Starwarp
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 ...
- A Starry turtleSpaces Logo Introduction Part One: Starfield
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 ...
