@aperture-engine/render

Renderer-independent ECS authoring, assets, extraction, and the per-frame RenderSnapshot contract for the Aperture engine.

Install

pnpm add @aperture-engine/render

This package is part of the Aperture WebGPU game engine and is normally used alongside the other @aperture-engine/* packages (it depends on @aperture-engine/simulation for the ECS world and asset registry).

What it does

@aperture-engine/render defines the authoring side of Aperture's render pipeline without depending on any specific GPU backend. You attach plain ECS components (Mesh, Material, Camera, Light, Sprite, UI nodes, particle emitters, audio emitters, and more) to entities, then extract a backend-agnostic RenderSnapshot for the frame. A separate renderer package consumes that snapshot to issue WebGPU work. The package also bundles glTF/GLB asset loading, KTX2/Draco/Meshopt/HDR decoders, material and mesh contracts, MSDF text atlases, and snapshot encoding/diagnostics.

Usage

import { createWorld, AssetRegistry } from "@aperture-engine/simulation";
import {
  registerRenderAuthoringComponents,
  extractRenderSnapshot,
  Camera,
  Mesh,
  Material,
  createCamera,
} from "@aperture-engine/render";

const world = createWorld();
const assets = new AssetRegistry();

// Register the render authoring components on the world.
registerRenderAuthoringComponents(world);

// Author a camera and a mesh entity.
world.createEntity().addComponent(Camera, createCamera());
world
  .createEntity()
  .addComponent(Mesh, { meshId: "my-mesh" })
  .addComponent(Material, { materialId: "my-material" });

// Produce the per-frame RenderSnapshot a renderer can consume.
const snapshot = extractRenderSnapshot(world, assets, { frame: 0 });

Entry points

This package exposes the following subpaths in its exports map:

• @aperture-engine/render — the full public API (assets, materials, mesh, rendering, text).
• @aperture-engine/render/test-support — extra helpers for inspecting snapshots, prepared resources, and the material queue in tests.
