Thanks to Bentley’s new scalable mesh technology, LumenRT can now visualise large scenes using actual engineering data, without having to go down the oneway optimisation route. This is fine for many visualisation workflows – as long as you don’t need to look too closely – but once the data has been approximated and averaged, it’s pretty much useless for any kind of engineering calculation. The traditional way to solve this problem is to decimate the mesh and reduce the number of polygons in the scene. And you can certainly forget about doing anything in VR. Trying to navigate a complex scene at only a few frames per second significantly impacts the experience and limits how useful it is. This puts a massive load on the GPU and slows down 3D performance. The datasets can be enormous, containing millions of polygons.
#LUMENRT 2D CAD HOW TO#
One of biggest challenges that engineering firms face is how to handle the complexity of large projects, which often include huge roads, long corridors and vast expanses of terrain. LumenRT has always placed a big emphasis on the visualisation of infrastructure projects but, since it came under Bentley’s control, this focus has grown.
#LUMENRT 2D CAD FULL VERSION#
Resolution is limited to FHD (1,920 x 1,080) and you’ll also need the full version if you want to take your designs into VR. LumenRT Designer contains most of the functionality of full-blown LumenRT, but has a slightly smaller environmental content library of vegetation, vehicles and characters. LumenRT has always been considered easy to use, but now Bentley is making a big effort to expand its reach by making a custom version available free of charge to those who use its CONNECT Edition design modelling applications. Two years ago, Bentley Systems got its own real-time rendering technology, LumenRT, with the acquisition of E-on Software. While static rendered images continue to play an important role in design exploration, it’s the realtime rendering tools – some of which also support Virtual Reality (VR) – that are currently generating the biggest buzz. Most BIM applications now have capable renderers built in and advanced tools like V-Ray are being tuned to the workflows of architects and engineers. Visualisation used to be the preserve of the design viz specialist, but this has changed dramatically over the past few years.
