Features

xeokit Software Development Kit An extensible open source JavaScript SDK to accelerate the development of Web-based BIM and CAD viewers.
Offline BIM viewing	View BIM models and IFC metadata loaded from the file system. [More info..]
Load models from BIMServer	View BIM models loaded from the leading open source IFC file server. [More info..]
Import multiple file formats	Load multiple models into the same 3D scene, from various source formats, including glTF, OBJ, 3DXML, STL, 3DS and BIMServer. [More info..]
BCF viewpoints	Save and load viewer state as BCF viewpoints. [More info..]
Section planes	Create cross-section clipping planes to reveal model structures.
Scene Metadata	A flexible IFC metadata graph to classify 3D scene content. [More info..]
Extensible with plugins	A growing library of bundled plugins to accelerate viewer development. [More info..]
xeokit Core 3D Library A complete WebGL-based 3D engine API at the core, designed for large-scale model viewing. Uses WebGL 1 for compatibility across a wide range of devices.
Physically-based materials	Physically-based rendering for realistic previews. [More info..]
Emphasis effects	Highlight and select objects, slice with cross-sections, emphasise edges.
3D Scene graph	Scene graph with dynamic transform and bounding volume hierarchy. Can contain models loaded from multiple sources and formats. [More info..]
Dynamic camera	Camera with orbit and first-person modes, perspective and orthographic projections. [More info..]
Camera animation	Animate the camera along paths for walk-throughs; fly the camera to focus on models and objects.
Dynamic light sources	Point and directional lights, light maps, reflection maps and skyboxes. [More info..]
Low memory footprint	GPU-resident geometry types to reduce browser memory footprint; automatic geometry compression. [More info..]
Efficient rendering	Optimized rendering for huge models, using state-sorting, geometry batching and instancing.
Picking	Pick objects and surfaces with pointers and rays.
