Unity Cubic Bézier Curve

![Sample Gif](https://github.com/adrian-miasik/unity-cubic-bezier-curve/raw/develop/promotional/cubic-bezier-curve-demo-preview.gif) ## About Unity Cubic Bézier Curve is a project used to demonstrate a 3D [bézier curve](https://en.wikipedia.org/wiki/B%C3%A9zier_curve) in Unity using line renderers. **Version**: 1.0.0 **Author**: **[`Adrian Miasik`](https://adrian-miasik.com)** **License**: [GPL-3.0](https://github.com/adrian-miasik/unity-cubic-bezier-curve/raw/develop/LICENSE) **Contributor(s)**: `-` Want to help?
