Principles of the programminglanguage LOGO

You need a lot of spatial imagination to place objects in space.

I use the principles of the programming language LOGO. That makes things a lot easier.

Each mesh is a “turtle” to which you can send commands, such as go 3 steps forward, turn 10 degrees to the left.

During my first attempts I unintentionally programmed a nice card mix.


lol excellent!

An other example of the power of Turtle Graphics: a simple snake animation! :slight_smile:



Hi @Necips I had the same problem with designing the train track layouts in from scratch: lack of accurate spatial imagination. So I changed to an approach of track laying similar to that of a turtle: draw track by moving an imagined turtle mesh. Works like a charm! (I’ve worked with SuperLOGO when I was a little child in primary school.) Funny of you mentioning the programming language and turtle approach :slight_smile: Q

I like your approach to a tedious looking train simulation.

I would also like to have a seat in the cockpit or a sight out of the passenger’s window, with a view of the Alps or the sea and hear the stapling of the rails, the quitting of the wheels when starting off, the noises arriving at the station, some passers-by getting on and off…

This animation is obtained by transferring the individual angles of the snake segment to a pyramid:

If you simply continue spinning crazy and transfer the snake movements to a nested cube, you will get… Art! :slight_smile:

Snake movements transfert to a set of bricks

Maybe someone need a cube folding/unfolding sequence… :slight_smile:


Yes I like these animations! :slight_smile:
I’m always passively looking for funny / geeky sample animations that make my scenes come to life.

These Playground samples above don’t seem to work in Firefox 66.0.3 but they do work in Chrome 73.0.3683.103. I get the error “fields are not currently supported”. Am I doing something wrong?

Thanks for your suggestions on my train game! If you want to receive updates, subscribe to my Demo thread on this forum, like the Facebook page or simply sign up in a snap on the game website (‘create free account’).

I have exactly the same issue with FF 66.0.3
