Private APIs needed to extract meshes and other information from your iTwin. It may make the most sense to develop your own integration with iTwin.js, especially if you have an existing mesh pipeline for dataĪll of the integrations, exports and examples described above were developed with our open source iTwin.js library. Building Your Own Integration With iTwin.js Still, the old source should work and may be helpful in your application. The iTwin.js monorepo also contained an open source OBJ exporterīut it was removed in favor of GLTF for internal testing. Select "Export to IFC" on the Named Versions page for your iModel on iModelHub. You can also use iModelHub to export IFC files from your web browser. The Export IFC service can be used to create IFC files from iModels. Use the Mesh Export service on to create GLTF 2.0 files from your iModels. Read more about LumenRT for NVIDIA Omniverse. ITwinXR supports reality data from iTwins. It is designed for mobile AR and Microsoft HoloLens. It works with desktop VR hardware (Oculus Rift, HTC Vive and SteamVR compatible headsets). If you are interested in an off-the-shelf solution that does not require custom development, there are several options.
This article is part of a Bentley Systems Year In Infrastructure special report. The big challenge for Bentley will be letting designers, engineers and architects know that it’s not just for Bentley customers.
LUMENRT AND OCULUC RIFT SOFTWARE
Now, with new VR capabilities, the software looks set to become an even more compelling tool for AEC professionals. We first saw LumenRT last year, and were hugely impressed by its quality, performance and ease of use. According to Bentley, as everything within the model is ‘instanced’, the memory footprint has been reduced dramatically, helping keep 3D performance levels high, even with large models. Once inside VR, ‘BIM hotspots’ will allow users to view the underlying BIM data simply by hovering over an object and clicking. The software can read in levels, layers, lights, animation paths and metadata. LumenRT doesn’t just bring across geometric data. Then, because the geometry is already optimised, moving into VR only takes a matter of seconds.įor distribution to clients and colleagues, projects can be packaged up as a ‘LiveCube’, a self-extracting executable. Getting CAD data into LumenRT only takes minutes to process, even with big scenes. Bentley says the workflow from CAD to VR is simple. In addition to MicroStation, AECOsim, SITEOPS and other Bentley tools, the software works with Revit, ArchiCAD, CityEngine and SketchUp. This decision was based on two factors: First, the ability of its engine to scale from small buildings to giant infrastructure projects, above and below ground, and second, the fact that it already had built-in tools for generating realistic AEC-specific features such as cars with wheels that move and traffic flows that are real, thanks to direct interfaces to MicroStation Traffic and VISSIM.ĬAD users outside of Bentley’s customer base will benefit, too. Three years in development, Bentley explored a whole range of VR game engines, such as Unreal and Unity, but decided to adapt its own engine instead. This will deliver a fully immersive, interactive experience where users can freely explore LumenRT’s 3D worlds populated with moving vehicles, animated characters and wind-blown skies.
LUMENRT AND OCULUC RIFT UPDATE
Things should get even more exciting next month when Bentley ships LumenRT Connect Edition Update 2, which will feature support for the Oculus Rift and HTC Vive.
