Experience around raylib binding for RUST to create a visualiser for Bézier curves and splines.

Spline drawer

This is a small projet around RUST, WASM and spline. The idea of this experiment came to me after seeing this incredible video. I wanted to test rendering (in an interactable way) Bézier curve and Bérzier spline using a homemade raylib project.

Why use Raylib

At first, I try setting up a version with the Bevy game engine for rust. However, I was felling like it was way too much for handling such a simple project. I then move to Raylib for a more lightweight experience. It is also important to note that Raylib is also well portable to WASM which became part of the project. In fact, by being able to compile to WASM the entire project it is way more convinient for people to test it using the Github Pages website.

Features

Well, if you have read until here, I will assume that you are kind of interesting in that project. Here is a quick list of the features and key binding:

• Press H to show the help panel with possible motions.
• While inside a scene use ESC to go back to the menu.
• Bézier curve (from 2 to 62 control points)
  • Use SPACE to add a new control point at the mouse position.
  • Use BACKSPACE to remove the last control point.
  • Use the GUI to play with the settings of the visualization.
• Bézier spline (only CPU is the limit)
  • Use SPACE to attach a new cubic Bézier to the spline. You cannot add new part to a close spline.
  • Use BACKSPACE to remove the cubic Bézier part or undo the close loop command.
  • Use ENTER to attach the end and the start of the spline to create a close loop.
  • Use the GUI to play with the settings of the visualization.
  • Use the GUI to lock & unlock control points & joint to create more smooth splines.
