Coming down with the sickness again, maybe there are codebase visualizations that are useful. Interactive with bidirectional editor integration and runtime analysis. Apologies for the slop prototype.

Let me get this straight, it is a set of PNGs of an AI eagle head with different brown colored feathers than the base AI eagle body. Got it.

Here is a VGGT example where all but one image is from daytime. The single nighttime image fails to integrate and is estimated to be in the free space to the left, outside the view of the daytime images.

The VGGT vision transformer model couldn't really handle mixed time of day images, but this new Apache-2 licensed model is a big step up. Variable lighting and weather really mess with existing VPS solutions. A popular one needs two scans at least 5 hours apart. map-anything.github.io

Got the mesh registration to run in ~100ms, down from 400ms, by fusing the kernels and moving the correspondence work to the gpu. The extra time is from deserializing the test data. bsky.app/profile/v1se...

These are 4 of the Mapillary images

The VGGT model works as a VPS with only a few images. One attention head estimates the 6dof camera pose of each image. Here is a rough example with 7 warped Mapillary images and 1 XR headset camera image in red. While the error is about 2m, you couldn't do this at all with SfM.

I got some very promising 3d sidewalk point cloud data from unwarping Mapillary data and feeding it to VGGT(Visual Geometry Grounded Transformer). The output seems much better than traditional Structure from Motion + Multi-View Stereo dense reconstruction.

I think I've hit the limit for GPS accuracy in the city for AR positioning. One path forward could be doing mesh registration on a 3d model of the city. Maybe by running Structure from Motion on the street level Mapillary data. Maybe combined with USGS airborne Lidar.

Ok, the GPS in red is so wrong here :(

I was really surprised by how well the tracking held up in the dark with visionOS 26.

Alleyway GPS sensor fusion test. Head position in white. GPS in red. Fused state in green. It is tuned for open fields and forests, but maybe with a bit more math this could hit sub meter accuracy. At this scale the odometry is very accurate.

I was surprised to find NOAA publishes the 3d weather forecast data for the continental US + Alaska. This appears to match observations of nearby mountains. Very little smoke today. I get why hiking apps don't provide search on this data now :), but there might be a way.

Would anyone actually try a free outdoor navigation app for the vision pro? The tech works in the mountains, but it is too dangerous to recommend outside flat parks. My initial tests were putting a 10m tall pushpin at a gps coordinate and keeping it there for miles.

Demo showing Claude building a race car with voxels. The UI is all buttoned up now, hopefully app review approves this feature.

Working on a little website to find hikes. One feature is filtering by weather forecast. Very thankful for the open data from NOAA and the USGS. All the blue dots are the real-time positions of nearly 1000 buses and ferries.
