## What it does

This skill guides the AI assistant on rendering custom geometry in PixiJS v8. It covers the base `Mesh` class with `MeshGeometry` alongside four specialized subclasses: `MeshSimple` for per-frame coordinate changes, `MeshPlane` for grid deformations, `MeshRope` for textures following a polyline, and `PerspectiveMesh` for 2.5D perspective planes.

All constructors in v8 take a single options object instead of positional parameters. Meshes act strictly as leaf nodes with `allowChildren = false`. Direct child addition triggers a deprecation warning, meaning grouping requires a standard `Container`.

Batching works only when specific constraints are met: standard `MeshGeometry`, no custom shaders or culling states, and 100 vertices or fewer under `batchMode = 'auto'`.

## When to use it
- build custom geometry buffers using MeshGeometry
- deform a textured plane using MeshPlane
- follow a polyline path with textures using MeshRope
- project 2.5D perspective planes with PerspectiveMesh
- animate vertex buffers every frame via MeshSimple

## Example prompts
- Create a MeshRope from an array of points with a stretching texture
- Set up PerspectiveMesh to tilt a 2D card in PixiJS v8
- Build a MeshGeometry using indices and triangle-strip topology

Meshes render arbitrary 2D (or perspective-projected) geometry with a texture or custom shader. PixiJS ships the base `Mesh` class plus four specialized subclasses for common shapes: `MeshSimple`, `MeshPlane`, `MeshRope`, and `PerspectiveMesh`. Pick the subclass that matches your shape; drop to the base `Mesh` when you need full vertex-level control or a custom shader.

Assumes familiarity with `pixijs-scene-core-concepts`. Meshes are leaf nodes; they cannot have children. Wrap multiple meshes in a `Container` to group them.

## Quick Start

```ts
const texture = await Assets.load("pattern.png");

const geometry = new MeshGeometry({
  positions: new Float32Array([0, 0, 100, 0, 100, 100, 0, 100]),
  uvs: new Float32Array([0, 0, 1, 0, 1, 1, 0, 1]),
  indices: new Uint32Array([0, 1, 2, 0, 2, 3]),
  topology: "triangle-list",
});

const mesh = new Mesh({
  geometry,
  texture,
  roundPixels: false,
});
app.stage.addChild(mesh);
```

Every `Mesh` subclass takes a single options object. The base `Mesh` requires a `geometry`; subclasses (`MeshSimple`, `MeshPlane`, `MeshRope`, `PerspectiveMesh`) build the geometry internally and require a `texture` instead. See each variant's reference for the full field list.
