Window and Frame Loop

Every graphics application starts with a window and a frame loop.

---

Create a Window

window is Window.Create(1280, 720, "My App");

Parameters:

• width as int
• height as int
• title as string

---

Frame Loop with Canvas

canvas(window) {
  OnFrame {
    cmd.Clear(Color(0.1, 0.1, 0.12, 1.0));
  }
}

OnFrame is where rendering work should run.

Rendering Scope Rules

• Renderer2D.Render(scene) is valid only inside OnFrame
• Renderer3D.Render(scene) is valid only inside OnFrame
• cmd.* drawing commands are intended for frame scope
