SIMKID: Toy motion simulator of simple physical systems for teaching kids

Teach kids physics and programming in parallel. This is a home-based project for practice Go with my younger son.

Details

In simkid the simulation space is a 1920✕1080 pixel area which is updated in 60 fps rate. All coordinates are given in pixels. Velocity and acceleration should be in pixel per frame [p/f] and pixel per frame per frame [p/f²] accordingly.

The main component of simkid is sim.go - simulation logic: put here individual equations of motion for maximum 10 balls and possibly add interactions between them.

Use simkid-ffmpeg.sh to compile PNG-frames into final MP4-video.

Usage

Clone the repo and run:

go run .
./simkid-ffmpgeg.sh
mpv "./videoset/$(ls -Art ./videoset | tail -n 1)"

Or having simkid artefact built with

go build .

simply watch the resulting video invoking

./simkid.sh
