“If a picture is worth a thousand words, then a 3D model is worth a million...”

Gone are the days where expensive LiDAR equipment is needed to create 3D models. Now all you need is your smartphone and the Travel Trails Android app to contribute points to a crowd sourced collection of 3D models that you can view on your phone. Check out some of our unique features.

Crowd Sourced

We fuse user photos into photorealistic 3D models of landmarks and monuments. Users can download the Android app to contribute images and view models on their phone.

Heatmap Overlay

We provide a heatmap overlay on each model to highlight areas that are low resolution. Users can then enhance the quality by including those areas in their photos.

Highly Interactive

Looking to interact with virtual models in new ways? Our models can be exported and post-processed into game assets, 3D printable objects, VR/AR experiences, and more!
