Welcome to Stereo3D, a real-time 3D stereogram viewer that displays rotating wireframe Platonic solids using the parallel stereogram technique. View true 3D without special glasses!

This application was built with Rust and the Macroquad game engine, creating a smooth, interactive 3D stereogram experience that works right in your web browser.

How Stereograms Work:
A stereogram creates a 3D illusion by presenting slightly different images to each eye. This app renders the same 3D Platonic solid from two camera positions (left and right eye), separated by a configurable distance. When viewed correctly, your brain merges these two images into a single 3D scene.

How to View the Stereogram:
1. Start close to the screen (12-18 inches) for easier initial fusion
2. Relax your eyes and look "through" the screen (like looking into the distance)
3. Focus on the red guide circles at the top of each view
4. Let your eyes merge the two images - you should see three shapes
5. Focus on the center shape - this is your 3D stereogram!
6. Once fused, slowly move your head back to 2-3 feet to maintain the 3D effect

Tips for easier fusion:
• Start with the default settings
• Use the red guide circles as a target
• Start close (12-18 inches) for easier initial fusion
• Once fused, move back to 2-3 feet to maintain the effect
• Adjust eye separation if needed (LEFT/RIGHT arrows)
• Try different perspective distances (UP/DOWN arrows)
• Practice with the pause feature (SPACE) to hold still images

The wireframe rendering includes depth-based coloring where closer wires appear brighter and farther wires appear darker, helping your brain understand the 3D structure.

Platonic Solids:
• Tetrahedron: 4 triangular faces, simplest 3D solid
• Cube: 6 square faces, most familiar solid
• Octahedron: 8 triangular faces, dual of the cube
• Dodecahedron: 12 pentagonal faces, golden ratio proportions
• Icosahedron: 20 triangular faces, dual of the dodecahedron

Projection Modes:
• Perspective (default): Traditional 3D view with realistic depth perspective
• Orthographic: Parallel projection with no perspective distortion - can be easier to fuse and shows geometric relationships more clearly

Optimal Viewing:
The app is designed with a narrow viewing area (440px width) that's optimal for stereogram fusion. This width provides the perfect balance between image separation and ease of merging.

I built this application with Cursor an AI Code Editor, the Rust language and the Macroquad Game Engine
