RE: fosstodon.org/@napari/1166165047810… And it's a wrap! The hackathon was a fantastic success! 🥳 You can look forward to a longer post about all we did, and one of our biggest releases yet in 0.9.0! Huge thanks to all the participants 🤩, and we hope to see you at the next one!

Speaking of annotation: if you've switched back and forth between annotating in 2D and checking your work in 3D, you know it can be disorienting! You can now sync the 2D and 3D cameras so that panning, zooming, and scrubbing around in 2D affects 3D view, and vice versa. Let us know if it helps you!

Annotating blobs just got easier with auto-fill of labels when right-clicking! Right click, draw your shape, and the whole shape gets auto-filled. This should give much faster annotations for many workflows!

*Finally*, napari gets a built-in histogram! It's still a work in progress but already *very* cool if we do say so ourselves, with live update based on the canvas and progressive, background update when computing on large full data.

Wait, wait, wait....v0.6.0 is just out, but there is already a next big feature coming to napari? Yes! You see it right 😊 (more impressive demo coming soon) . Our own @brisvag has been doing work on multichannel grid mode which is to replace our current grid […] [Original post on fosstodon.org]

@czaki has made huge improvements to the Shapes layer, supported by a CZI grant to the Spatial Data team. We've launched a *fast* triangulation library written in Rust (called bermuda 😉), making Shapes up to 200x faster! Read more: napari.org/stable/guides/triangulat…

Axis praxis! You can now point the depth, vertical, and horizontal axes any which way! We've fixed the handedness of the 3D view — DNA helices are again right-handed 😅, and if you have map data you can make latitude point north. Check out our new guide! […] [Original post on fosstodon.org]

And it's finally here! napari 0.6.0 is out on PyPI and conda-forge! 🥳 We've had a few threads about this release already but let's recap with some highlights: 🧵

BIG change since 0.6.0a1, the culmination of months of work: we've made major improvements to triangulation (splitting polygons into triangles for drawing on the GPU), resulting in up to 200x while improving accuracy. We can now accurately draw South Africa with its enclave Lesotho.

Hello all, Hopefully the last community meeting now before 0.6.0 lands 😅 This has been a lot of hard work the last weeks by multiple people! Want to discuss the release or have any napari questions for core devs or want to show a cool demo? Come join tomorrow! […] [Original post on fosstodon.org]

Did you notice that cool new camera parameters menu? That and other right-click menus are easier to discover thanks to new core dev (!) Tim Monko — check the little indicators! *And*, check the cute new canvas dimensionality toggle! And did you notice view angle is preserved now? 😉😍

What do structural biologists and atmospheric scientists have in common? They care which way their axes point! In napari 0.6.0, we finally default to a right-handed reference frame in 3D. But don't panic, we also let you customise axes directions from the API, UI, or startup preferences!

Thanks to Hanjin Liu, napari now has a command palette! 🎨 This thing is really nice to use — the core team can no longer live without it — and it even works with plugin commands! 🤩
