A bound <code>animCam</code> plays a four-keyframe track; a separate <code>viewCam</code> orbits around the abstraction — eye polyline, gaze rays, per-keyframe mini-camera markers. A live frustum follows playback, and an FBO inset shows what <code>animCam</code> actually sees. Toggle <code>TEX</code> and that inset slides onto the live frustum&rsquo;s near plane — the frustum becomes a window. Two <a href="https://github.com/VisualComputing/p5.tree"><code>createPanel</code></a> instances drive the whole thing: one binds checkboxes to UI state, one binds transport controls to the track.</p>
