3D wallpaper with head tracking: a practical explanation

What makes the effect feel three-dimensional?

Holoscape uses a webcam to estimate the position of your head relative to the screen. The scene renderer then shifts the virtual camera by a small amount. Nearby objects move more than distant objects, creating motion parallax—the same depth cue your eyes use when looking out of a moving train window.

What you need

• A Windows PC with a working webcam.
• A scene with layered or spatial 3D geometry.
• Enough GPU headroom for the chosen scene and display resolution.

Why subtle movement looks better

The goal is not to make the whole desktop swing around. The best result is a restrained camera response: the scene stays comfortable to watch, while edges, planets, forests, and rooms gain a convincing sense of distance. You can see the approach in the Holoscape scene gallery.

Is webcam video recorded?

Holoscape is designed around the tracking signal rather than a video feed. Review the privacy policy for the current product and analytics data practices.
