Project Overview

This project explores a procedural spline tool within Unity through two implementations. The first is a custom Catmull-Rom Spline tool that allows easy manipulation of splines to form complex paths through collision-based deformation, control handles, and adjustable parameters such as curvature control, segment point offsets, segment resolution, closed-loop splines, and Perlin noise. The second focuses on procedural mesh generation along both Catmull-Rom and Bézier splines, with extended functionality of mesh generation along Bézier splines, to generate a roller coaster-style geometry.

Challenges

The biggest learning curves were understanding of how splines can be created, modified, and interpolated, as well as how to index and position vertices that form triangle meshes of the desired shape along the spline.
