Weddings in Action

Inspiration

A friend of mine recently celebrated their one-year wedding anniversary, and it made me think about how static wedding photos feel compared to the memories they represent. Weddings are inherently spatial experiences — the venue, the ceremony, the dance floor, the people moving through the space.

I wondered whether recent world-model tools could transform wedding albums into explorable environments instead of static images.

What it does

Weddings in Action turns a wedding photo album into a collection of explorable 3D worlds.

Using a set of wedding photos, the system reconstructs immersive scenes that users can navigate through. Instead of flipping through pictures, you can move through the venue and revisit the physical space where the memories happened.

Right now each reconstructed scene exists as its own world, but the long-term vision is a fully navigable wedding experience — essentially a spatial memory of the entire day.

How we built it

We built the prototype using the Marble API from World Labs to generate 3D environments from sets of photos.

The pipeline works roughly as follows:

1. Upload wedding photos
2. Send the images to the Marble API for scene reconstruction
3. Receive a generated 3D environment for each set of photos
4. Present each reconstructed environment as a navigable scene

The result is a series of reconstructed spaces derived directly from the original photo album.

Challenges we ran into

World stitching
Each generated environment currently exists in isolation. Turning multiple scenes into one continuous experience is difficult with the current API and would require manual editing and spatial alignment.

Human reconstruction
People do not render well yet in current world models. Faces and bodies often degrade or distort during scene generation.

Editing limitations
Creating a cohesive multi-scene experience requires significant individual editing of each generated environment.

Accomplishments that we're proud of

• Turned a traditional wedding photo album into navigable 3D environments
• Demonstrated a new form of memory preservation beyond photos and video
• Built a working prototype using cutting-edge world model infrastructure

Even as separate scenes, the environments already create a compelling sense of stepping back into a moment.

What we learned

World models are incredibly powerful for reconstructing spaces, but they still struggle with people and continuity between scenes.

However, this suggests an interesting future: memories may be captured once, and then recompiled into higher-fidelity worlds as models improve.

Your wedding album could literally get better over time.

What's next for Weddings in Action

Next steps include:

• Scene stitching to connect environments into a continuous explorable world
• Better human reconstruction so people appear accurately in scenes
• Album recompilation so old albums can be reprocessed with newer models
• Timeline navigation to move between moments of the wedding day

The long-term goal is to turn photo albums into living spatial memories.
