Graphics Quick Start

This is the smallest practical graphics program: open a window and draw a mesh.

Minimal Example​

BasicLit is shader {
  tint as Color;

  Vertex method(position as Vector3) {
    return MVP * position;
  }

  Fragment method() {
    return tint;
  }
}

Init method() {
  window is Window.Create(800, 600, "Quick Start");
  mesh is Mesh.Load("examples/assets/triangle.obj");
  material is Material<BasicLit>();
  material.tint is Color(1.0, 0.2, 0.2, 1.0);

  canvas(window) {
    OnFrame {
      cmd.Clear(Color(0.08, 0.08, 0.10, 1.0));
      cmd.DrawIndexed(mesh, material);
    }
  }
}

What This Shows​

  • Window.Create creates the native window
  • shader defines GPU stages
  • Material<ShaderType>() creates a typed material
  • canvas(window) starts the frame loop
  • cmd.Clear and cmd.DrawIndexed issue per-frame commands
