Home / dynamic terrain trail viewer /

Here is the new project I m working on (trk-360) using the marvellous babylonjs webgl engine The pitch is quite simple, upload a gpx/geojson file of your last activity(sport, car, plane, etc), take a seat and watch all of this in 3d. It uses dynamic tiling for texturing and dynamic tile elevation to increase relief detail. The app is still not online. So here is 3 videos of the UTMB Trail (170km) in the Italian/French Alps with different view mode. I still have a lot of work to optimized all of that. The trail path is for now quite ugly. Tile elevation decoding have to be pass on gpu side, motion camera need improvment and lots of other things to do or finalize... video can be a bit choppy due to the software capture
