I’m generating a track/road using an extruded Plane based on an example by @hofk like so:

```
import {
BufferAttribute,
CatmullRomCurve3,
PlaneGeometry,
Vector3,
} from 'three'
const controlPts = [
new Vector3(0, 0, 0),
new Vector3(10, 0, 0),
new Vector3(100, 0, 0),
new Vector3(0, 0, 10),
]
const curve = new CatmullRomCurve3(controlPts, true)
const spacedPts = curve.getSpacedPoints(1000)
const extrudedGeometry = extrudePath(spacedPts, 1)
function extrudePath(points: Vector3[], depth: number): PlaneGeometry {
const numOfPoints: number = points.length
const geometry = new PlaneGeometry(0, 0, numOfPoints - 1, 1)
const pos = geometry.attributes.position as BufferAttribute
for (let i = 0, p; i < numOfPoints; i++) {
p = points[i]
pos.setXYZ(i, p.x, p.y, p.z + depth)
pos.setXYZ(i + numOfPoints, p.x, p.y, p.z)
}
geometry.computeVertexNormals()
return geometry
}
```

I don’t really know how to visualize a set of Vector3 points to create different kinds of roads. For example, what would the set of Vector3 points look like for a traditional oval ring race track? What if I wanted a road that had some twists and turns and hills? Is there a visual editor that can spit out a set of points to pass to the `CatmullRomCurve3`

constructor? Could you draw something in Figma, export to an SVG and somehow convert the SVG path to a set of points?

I’m not sure where to begin in terms of generating a variety of roads.
