How Do I Make a Rotating Spirograph Laser Animation?

In BeamTracer Laser's ANIMATION STUDIO, Command-click or Ctrl-click Spirograph under QUICK TOOLS, then choose Spinning Star from its generator library. Use ROTATION to set the spin and Snap to Loop to fit the timeline. Play the animation, download its ILDA file, and open that file in ILDA Viewer to check the result.

Hi, I'm Trina with BeamTracer.com. This lesson starts with a built-in curve, so you can work on its movement without importing artwork. We'll compare the complete rotating shape with a three-second draw reveal, then look at the exported animation from a moving camera.

The same exported Spinning Star file shown later in this lesson, playing in Cinema view with Orbit Mode. This is a simulated preview.

How do I add the Spirograph and save an animation?

Open Animation Studio and find Spirograph in QUICK TOOLS. Command-click it on a Mac, or Ctrl-click it on Windows, to place a centered shape. Select the shape to see its generator settings in the properties panel.

The LIBRARY menu includes static patterns and animated starting points. Choose Spinning Star for this example. Its rotation is already enabled, and its rainbow colors change while it plays. Keep those preset settings for the first take so you have something to compare with later.

The recorded example runs for 6.30 seconds on the timeline at 30 frames per second. Its downloaded file contains 189 frames. You can inspect that file independently in ILDA Viewer.

How do I change how fast the pattern rotates?

Select the Spirograph and find ROTATION in its generator's ANIMATION section. Moving the slider changes the spin speed. The Spinning Star preset displays about 0.3π/s; leave that value in place to follow this example.

With DRAW ANIMATION set to INSTANT, the whole curve stays visible as it rotates. The settings panel shows the rotation speed and rainbow cycle speed separately.

Snap to Loop fits the duration to the rotation. In this example, the control reports a rotation period of about 6.28 seconds, and the frame-based timeline ends at 6.30 seconds. Watch the transition when playback repeats before deciding that a take is finished.

How do I make the curve draw itself while it spins?

Use DRAW ANIMATION in the same generator section. INSTANT shows the entire curve from the start. Set it to 3.0s for a gradual reveal, then play from the beginning. Keep the rotation setting unchanged to see how the drawing and spinning combine.

This take uses a three-second draw reveal. Watch the visible path grow after the timeline returns to the start.

After changing the reveal or rotation, download the animation again to save that version. The earlier file remains a separate take; changing the editor does not update a file you already downloaded.

How do I inspect the exported file in Cinema view?

Load your saved .ild file into ILDA Viewer. Read FILE INFO and FILE HEALTH before switching views. The instant-draw example in this lesson reports Format 5 (2D True Color), 189 frames, and an EOF marker marked Present.

Choose 3D, open SCENE, and select Cinema under BEAM MODE if your plan includes it. Choose Orbit Mode from the camera presets. The first clip on this page uses those settings with the downloaded file.

Cinema adds a simulated environment around the file's pattern. Use it to examine the movement and camera view; check the actual file information as well when preparing an export.

What should I check before using a projector?

Read the viewer's notes alongside its point budget. This example reports roughly 13 kpps at 30 FPS against a selected 30 kpps device rate. It also flags frequent stored color transitions. That note describes the file's color changes; visible strobing is not measured.

FILE HEALTH checks the file structure and estimates point load. It does not measure scanner stress or certify laser safety. A rotating shape looking smooth in the browser is useful editing feedback, but projector setup and the projection environment still need their own checks.
