The notes from your dev chat are spot on, particularly regarding the browser
deployment. Because we are using SharedArrayBuffer and Atomics for
zero-latency memory synchronization, the browser absolutely requires strict
cross-origin isolation headers (Cross-Origin-Opener-Policy and
Cross-Origin-Embedder-Policy). We will need to ensure our local development
server serves these headers, or the browser will block the memory allocation.
While the dev chat suggested raw WebGL (gl.bufferData), sticking to our plan
of using Babylon.js is the optimal path. Babylon will handle the lower-level
buffer binding and matrix math, allowing us to interact with custom geometry
much like you did with scene::SMeshBuffer in Irrlicht.
Here is the delegation prompt for Phase 3.
Phase 3: Delegation Package
Copy and paste the following into your code-generation session:
> System Context: We are building a WebGL port of a voxel engine. I already
have a main-thread ChunkManager and a Web Worker connected via an SPSC
SharedArrayBuffer Ring Buffer. The worker successfully generates a flat
Float32Array of raw vertices and transfers it back to the main thread.
> Task: Implement the CHUNK_RENDERER using Babylon.js and set up the local
browser environment.
> Technical Requirements:
>  * Local Dev Server: Provide a minimal configuration (e.g., Vite or a simple
Node.js Express script) that serves static files with the required
cross-origin isolation headers (Cross-Origin-Opener-Policy: same-origin and
Cross-Origin-Embedder-Policy: require-corp) so SharedArrayBuffer works in the
browser.
>  * Babylon.js Initialization: Create a basic HTML file with a <canvas> and a
TypeScript entry point that initializes a Babylon.js Engine, Scene,
UniversalCamera, and HemisphericLight.
>  * The ChunkRenderer Class:
>    * Write a class that listens for the worker's mesh message.
>    * Take the transferred Float32Array of vertices and map it to a custom
BABYLON.Mesh using BABYLON.VertexData.
>    * Since we are only generating raw triangles right now (no indices or
normals yet), compute the normals dynamically using Babylon's built-in
VertexData.ComputeNormals.
>  * Integration: Hook up the existing Ring Buffer push command so that
clicking a button (or running a timeout) sends an edit to the worker, receives
the array, and renders the 3D mesh on the canvas.
>  * Correction: Ensure the worker and data structures explicitly use a chunk
size of 8x8x8 to align with our established voxel memory arena.
> Output Requirement: The local dev server script, the index.html file, and
the renderer.ts implementation.

Moving Forward
Once this session is complete, you will have a fully functioning, visual
vertical slice running in your browser. You will be able to push edits into
the queue, watch the Web Worker process them, and see the resulting geometry
drawn on the canvas by Babylon.js.
After we verify this render adapter works, we will have reached our MVP
milestone. At that point, would you prefer to focus on optimizing the mesh
pipeline (implementing greedy meshing and face culling) or building out the
RAYCAST_SELECTOR so you can click and edit the blocks directly in the 3D view?
