Markerless AI Tracking Transforms Fencing Into Real-Time 4D Geometry
By

Markerless tracking on every sword tip overlaid on live footage in real time. Fencing becomes a 4d geometry problem where both players are solving for the same point in space & time. Watching 3d trajectories render live like this is doing something to my brain I cannot explain. https://t.co/FPF18gqDMU

Holy crap, NVIDIA just made it drastically easier to create large scale explorable 3d worlds.

No manual stitching of smaller 3d generations like other 3d models. Lyra 2.0 looks pretty damn impressive. pic.twitter.com/GcTGm3oMHeHoly crap, NVIDIA just made it drastically easier to create large scale explorable 3d worlds.
