Blog > Slot car track editor

This is an slot car track editor I built back in 2015 to avoid trial an error when setting up tracks.

During development (an earlier attempt used Logo, see below), I opted for Typescript to implement the different transformations required to compose the full track (rotations, translations).

Source code is available in this repository: https://github.com/ramongilmoreno/slotdesign.

Full screen editor can be accessed here.

Below is the original Logo souce. Can be tested here.
