Double-precision geometry keeps models in their global coordinates, so they line up with GIS data.
Clash detection, issue list and BCF export
Coordination and issue tracking
Find clashes, measure, cut sections and share issues as BCF viewpoints with your other BIM tools.
BCF viewpoints are exchanged with other BIM software, so issues do not stay locked in one tool.
LiDAR scan and IFC model in one scene
LiDAR scans together with BIM
View point clouds from LAS and LAZ in the browser, also in the same scene as your BIM models.

Read the Hamburg and Zurich user stories »“Incredibly fast load times and super high-performance rendering, even on mobile browsers. Built in a modular way that allowed us to easily customize its behaviour.”
“xeokit's rich features and detailed documentation allow us to create interactive and customizable web visualization experiences for large-scale BIM models.”
“From the start, Creoox proved to be a reliable partner: attentive, open to feedback, and aligned with our expectations, which led to a performant solution that streamlined workflows and improved user experience. Their fast, expert support made the process smooth and effective.”
“We have been very impressed with the xeokit SDK's features. Of particular note is xeokit's highly efficient binary .XKT model format, which makes loading and rendering large models faster than ever before. With the wide-ranging feature set offered by the SDK, we have been able to meet most of our product goals so far.
Our developers have also spoken about their positive experience. They noted the active development of the project and the quick and helpful responses from xeolabs whenever they had any issues.”

FAQ#
Q: What makes xeokit special?
When it comes to high-performance BIM/AEC visualization, xeokit has several capabilities that set it apart from standard Web graphics libraries:
- Fast loading - ultra-compact native file geometry format loads hundreds of thousands of objects over the Web in seconds.
- Fast rendering - purpose-built to fluidly visualize hundreds of thousands of objects in the browser.
- Double-precision rendering - accurately view building model geometry in global coordinates, enabling GIS applications.
- BIM/AEC-friendly programming API - a complete JavaScript graphics programming toolkit, with an API designed specially for BIM/AEC applications.
- Plugins - a library of plugins to accelerate BIM/AEC application development.
- Freedom - host viewer, models and conversion tools on your own servers - no issues with data sovereignty, no reliance on 3rd-party cloud services.
Q: Who is using xeokit?
A growing, international community of industry leaders, researchers and hackers.
Q: Who are the people behind xeokit?
Behind xeokit you’ll find the team at Creoox AG — experienced software graphics engineers, civil engineers and innovators dedicated to maintaining xeokit as a powerful and evolving tool for 3D visualization within AEC & BIM.
Q: Which WebGL library does xeokit use?
The xeokit SDK has its own WebGL engine, which is specially designed to visualize complex, full-precision BIM and engineering models.
The engine uses our own special blend of techniques to interactively render models containing hundreds of thousands of individual parts, in all major browsers, including mobile.
The engine also distinguishes itself by supporting double-precision rendering on WebGL, which only supports single-precision natively. This means that we can render buildings in their original, global coordinate system, without rounding errors and fitting perfectly with GIS data. [Try a demo]
Q: What file formats does xeokit load?
The xeokit SDK loads (at least) IFC (2x3 & 4.3), CityJSON, glTF, OBJ, 3DXML, LAS, LAZ and XKT.
XKT is xeokit's highly-optimized native geometry format, which allows xeokit to load hundreds of thousands of full-precision objects in seconds. XKT files are converted from various source formats using open-source CLI tools.

Q: How do I view my IFC file with xeokit?
Use open-source CLI tools to convert IFC (2x3 and 4.3) files into xeokit's compressed native model format, XKT, which xeokit can then load super quickly into its browser-based viewer.
The XKT format contains all the model's geometry and elements, along with some basic metadata to help navigate the IFC types. The format greatly reduces the model size. As an example, the 49M IFC file for the Schependomlaan sample model converted into an 1.5M XKT file, which xeokit loads in around ~2-3 seconds over a good Internet connection.

Q: Can I edit and save IFC files with xeokit?
Yes, with xeoIFC, part of the xeokit Data Engine. It reads, edits and writes IFC 2x3, 4 and 4.3: change models from scripts, from your own software or with an AI assistant, split and merge them, and save the result as IFC. It runs in your own environment or as a managed service by Creoox AG.
The open-source xeokit SDK itself does not author IFC: it is a front-end visualization toolkit, built to view and interact with large models in the browser.
