shader-object

A modular library for packed GPU struct schemas + Babylon include emitters with optional AssemblyScript kernels.

Install

npm i shader-object
npm i @babylonjs/core  # or: npm i babylonjs

This package treats Babylon as a peer dependency. You must have either @babylonjs/core (ESM) or babylonjs (UMD) installed.

Build

npm run build

Usage (quick sketch)

import { ShaderObject, gpuStruct, field } from "shader-object";

@gpuStruct({ name: "ActorPool" })
class ActorPool extends ShaderObject {
  @field(0, "mat4") transform!: Float32Array;
  @field(1, "vec4") color!: Float32Array;
  @field(2, { arrayOf: "vec3" }) velocities!: Float32Array;
}

// Initialize kernels + includes (once per class)
await (ActorPool as any).initialize(engine);

// Use
const pool = new ActorPool(engine);
pool.color = new Float32Array([1,0,0,1]);
pool.setVarArray("velocities", new Float32Array([0,1,0, 1,0,0]));
