Custom shaders bind GLSL and WGSL programs to scene objects via Shader.from({ gl, gpu, resources }). Uniforms live in typed UniformGroups, textures are passed as separate resources, and the same shader can target both WebGL and WebGPU.

Quick Start

const uniforms = new UniformGroup({
  uTime: { value: 0, type: "f32" },
});

const shader = Shader.from({
  gl: { vertex: vertexSrc, fragment: fragmentSrc },
  resources: { uniforms },
});

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]),
});
