- For
- Apple Vision Pro users curious about spatial geometry
- Worth noticing
- The site contrasts a whole-object projection with the exact 3D shape where a moving W-plane intersects it.
Field notes
The page frames projection and section as different views: one compresses the whole object into 3D, while the other shows the exact shape meeting the current slice. Its listed experiments range from throwing a hypersphere through W to folding six squares into a cube and eight cubes into a tesseract. The site says the visionOS app includes guided lessons, open Lab tools, and immersive worlds, but gives no release date.
