What is OpenVDB?
Half-precision grids and a NanoVDB that finally handles changing topology
OpenVDB ships one major version a year with sparse patch releases in between, and many older tags carry no notes beyond a link. The recent substance is concentrated in 12.1.0 and 13.0.0: a batch of level set construction tools, principal component analysis on point distributions, anisotropic surfacing operators, and then Half Grid support both in memory and serialized into the file format. NanoVDB has been steadily accumulating tools alongside the core library.
What is Webflow?
Webflow is building for the answer engines, not just the search results page.
The centre of gravity has moved to AEO — answer-engine optimization. Webflow now runs your prompts through Perplexity alongside ChatGPT, Gemini, and Claude for visibility and citation comparison, and has shipped agents that recommend content, write briefs, and draft copy aimed at getting cited. Running underneath is steady builder-surface work: bulk select-option creation, attribute strings that split on paste, a dockable AI assistant, and per-language tone and formality control for translations.

Half-precision grids and a NanoVDB that finally handles changing topology
◆ Current state
OpenVDB ships one major version a year with sparse patch releases in between, and many older tags carry no notes beyond a link. The recent substance is concentrated in 12.1.0 and 13.0.0: a batch of level set construction tools, principal component analysis on point distributions, anisotropic surfacing operators, and then Half Grid support both in memory and serialized into the file format. NanoVDB has been steadily accumulating tools alongside the core library.
◆ Where it's heading
Two directions are visible. Precision and memory footprint are being treated as a first-class tuning axis — Half Grids halve storage for volumetric data, with the notes flagging that algorithm adaptation for performance and precision is still to come. Separately, NanoVDB is escaping its original niche: built for static rendering, it now covers level set tracking, grid building, morphology and merging, which are dynamic-topology problems.
◆ Prediction
The 13.x line should follow through on the stated plan to adapt algorithms for Half Grids, since shipping the format and in-memory support without the optimized code paths leaves the feature half-delivered.
Webflow
7.5DESIGN
Webflow is building for the answer engines, not just the search results page.
◆ Current state
The centre of gravity has moved to AEO — answer-engine optimization. Webflow now runs your prompts through Perplexity alongside ChatGPT, Gemini, and Claude for visibility and citation comparison, and has shipped agents that recommend content, write briefs, and draft copy aimed at getting cited. Running underneath is steady builder-surface work: bulk select-option creation, attribute strings that split on paste, a dockable AI assistant, and per-language tone and formality control for translations.
◆ Where it's heading
The AEO line is being built as a full loop rather than a dashboard — measure citation share across four models, then generate the content intended to move it. That closes the gap between analytics and authoring inside one tool, which is a different proposition from an SEO plugin. The visual-builder releases in the same window are small and ergonomic by comparison, suggesting the canvas is in maintenance while the AI surface absorbs the new capability.
◆ Prediction
Model coverage has expanded once already in this window, so adding further answer engines to AEO analytics is the cheapest next step. The more telling question is whether the AEO agents stay advisory or start publishing directly to the site — the drafting capability is already there, and only the hand-off is missing.
