Low-Level Draw Commands

Use cmd in OnFrame when you want explicit render commands.

---

Clear and Draw

canvas(window) {
  OnFrame {
    cmd.Clear(Color(0.07, 0.08, 0.10, 1.0));
    cmd.DrawIndexed(mesh, material);
  }
}

---

Draw Variants

• cmd.Draw(mesh, material)
• cmd.DrawIndexed(mesh, material)
• cmd.DrawInstanced(mesh, material, instances)

---

Typical Pipeline

1. Load mesh and textures once in Init
2. Create Material<Shader>()
3. Set material fields (Color, Texture2D, Sampler)
4. In OnFrame, clear and draw
