Avogadro Project @avogadro.cc · 01/10/2026What's this? Avogadro2 in a web browser?! #compchem #opensource #prototype 0236
Avogadro Project @avogadro.cc · 14/09/2026Looks like a 60 / 40 split in favor of "Z-Matrix Editor" so we'll try to jam "internal coordinates" in there somehow. 000
Avogadro Project @avogadro.cc · 11/09/2026Well, it's a 3D editor.. 😀 There are some interesting ideas to get Avogadro2 working on the web. Need a bit more tooling, but probably sometime next spring. The big trick is full v3000 support, e.g. dative, haptic bonds, etc. but suggestions and help are definitely welcome! 110
Avogadro Project @avogadro.cc · 11/09/2026Yes, that's the general idea. If you decide you want the distance to go from atom 4 instead of atom 2, it'll figure it out. We're just trying to gauge how many people use the two terms. You should be able to test it out in the continuous builds now avogadro.cc/install/avogadro.ccInstall — Avogadro 2.0.0 documentation 010

Reposted by Avogadro ProjectGeoff Hutchison @geoffhutchison.net · 29/08/2026A few weeks ago, I posted for the 2026 Avogadro Community Feedback Survey. Over 50 people responded, and several wrote multi-paragraph responses! I posted a summary to the forum and I want to include a few notes for #compchem discuss.avogadro.cc/t/avogadro-2...discuss.avogadro.ccAvogadro 2026 Survey ResultsA few weeks ago, I posted the 2026 Community Feedback Survey - and I’d like to start doing this annually.

Avogadro Project @avogadro.cc · 06/04/2026Avogadro 2.0 isn't just a viewer and editor — it's an extensible platform for chemistry A plugin system lets you add ML & electrostatic models, new builders and tools.

Avogadro Project @avogadro.cc · 05/04/2026Also, not sure if MMFF94 (used for this) is the best choice for liquid water. On the other hand, it's useful to switch between say UFF (which lacks electrostatics and h-bonding terms) and MMFF94. At the moment, we don't yet have support for various water models (TIP3P, TIP4P, SPC, etc.) 040
Avogadro Project @avogadro.cc · 05/04/2026Yes, this didn't start from an equilibrated water box, so the density is wrong. If you've got some good suggestions for initial starting points (e.g., for teaching purposes), they'd be greatly appreciated! 110
Avogadro Project @avogadro.cc · 05/04/2026Sometimes you just want to see a molecule move. Run a quick MD simulation without leaving Avogadro — no scripts, no setup. The new auto-optimize tool includes a dynamics mode. Watch it move in real time. Great for teaching. Great for intuition. Just fun to watch. #openscience #compchem #opensource 1213
Avogadro Project @avogadro.cc · 04/04/2026Visualize molecular orbitals and electron density easily with Avogadro 2.0. Volumetric rendering of orbitals, plus van der Waals, solvent-accessible and solvent-excluded surfaces for biomolecular work. See the chemistry, not just the atoms. #compchem #openscience #opensource 0175

Avogadro Project @avogadro.cc · 02/04/2026Avogadro 2.0's rendering was rebuilt for modern GPUs. Smooth even with tens of thousands of atoms. Real-time shadows and ambient occlusion give depth and clarity — and a new layer system lets you hide solvent, toggle styles, and focus on what matters. #opensource #openscience #compchem 0184
Avogadro Project @avogadro.cc · 01/04/2026No fooling, Avogadro 2.0.0 is finally here!

Avogadro Project @avogadro.cc · 15/09/2025The atoms have essentially infinite resolution, but the real-time shadows / ambient occlusion does not. The latter looks better on high-resolution screens. Having reflectivity as an option seems useful - please post a feature request 010
