# Objective

- As discussed on
[Discord](https://discord.com/channels/691052431525675048/1203087353850364004/1285300659746246849),
implement a `ConvexPolygon` 2D math primitive and associated mesh
builder.
- The original goal was to have a mesh builder for the simplest (i.e.
convex) polygons.

## Solution

- The `ConvexPolygon` is created from its vertices.
- The convexity of the polygon is checked when created via `new()` by
verifying that the winding order of all the triangles formed with
adjacent vertices is the same.
- The `ConvexPolygonMeshBuilder` uses an anchor vertex and goes through
every adjacent pair of vertices in the polygon to form triangles that
fill up the polygon.

## Testing

- Tested locally with my own simple `ConvexPolygonMeshBuilder` usage.
