AI Analysis

●●SolidEye CandyRabbit Hole

3D stroke projection onto panorama geometry beats flat 2D overlays.

Strengths
  • •Strokes wrap around building geometry instead of floating flat.
  • •Real-time multi-user visibility creates a living global canvas.
  • •Uses Mapillary API for open street-level imagery access.
Weaknesses
  • •Mapillary coverage is significantly sparser than Google Street View.
  • •Novelty may wear off without deeper gamification or utility.

Post Description

Hey HN, I made a site where you can draw on street-level panoramas. Your drawings persist and other people can see them in real time.

Strokes get projected onto the 3D panorama so they wrap around buildings and follow the geometry, not just a flat overlay. Uses WebGL2 for rendering, Mapillary for the street imagery.

The idea is for it to become a global canvas, anyone can leave a mark anywhere and others stumble onto it.
