The goal of this project was to create a visualisation similar to that shown in this video, I was inspired by this amazing video explaining all the maths behind this visualisation.
Here is an example of it in action:
This guide is for linux/WSL, so it may differ for Windows users.
- Ensure you have Rust
- Install the libsdl2 development libraries, for Ubuntu/WSL this would be
sudo apt install libsdl2-dev - Clone the repository
- If wanted, modify the
"example.svg"to the path of whatever SVG you want insrc/lib.rs - Run
cargo runorcargo run --release(Latter option will take longer to build but should run a bit better) - Enjoy!
If you are using WSL, you may want to use an X server. I suggest this stackoverflow answer (pay particular attention to the instructions about Windows Firewall), it's what I used.
| Input | Action |
|---|---|
| Click (hold) and drag | Moves view |
| Scrollwheel | Zooms in and out centred at the mouse |
| R | Resets visualisation |
| - | Slows down visualisation (a bit buggy, press R) |
| = | Speeds up visualisation (a bit buggy, press R) |
| L | Locks camera to the drawing tip |
- Fix speeding up/slowing down visualisation
- Fix weird bug where the drawn line falls behind where it should be drawn (press L and zoom in to see what I mean)
- Implement the maths for Elliptical Arcs
- Command line arguments for specifying what SVG, window size, etc.
- Resizable window
- Graphics acceleration? (would probably require a rewrite)
- Saving to gif/mp4
- Support SVGs with multiple paths
