Bricscad Revit Killer

Looking for a good alternative to Archicad or revit? Bricscad might just be the software for you! This amazing BIM program not only lets you do everything ar. 2 days ago  Plex-Earth, a platform for AutoCAD that brings many aerial and satellite imagery providers under a single umbrella, announced it has expanded its offering to BricsCAD to inform smart engineering with recent, historical, high-quality imagery and terrain data. By leveraging the power of premium imagery from providers like Maxar, Airbus, Nearmap, Hexagon or Google Maps within BricsCAD.

Bricscad vs revit

That's the essence, or one of the essentials, of Point Cloud enablement - algorithms to make display rotation etc go just as fast as with a relatively 'light' vector model, when meshes and point clouds are usually extremely 'heavy'.

Bricscad Vs Revit

Don't know how pure-mesh based 3D modellers do it, but un-enabled CAD (like present Brics) simply stalls, however hot the graphics card.

I have an ancient copy of PointTools, which rotates large point clouds splendidly, with decimation (temporary drastic simplification) of the image while rotation is happening, and re-appearance of the full image when rotation stops. Bentley bought PointTools, which is now their Point Cloud engine - but rotation is not nearly as satisfactory as implimented in Microstation - 'only partial implimentation' apparently - don't know why.

I understand that decimation is done by creating ten or so different LoD versions of the model, which are deployed as necessary depending on how challenged the graphics card feels. Such decimation may be an essential part of VR, while the image is moving - maybe decimation cleverness within some VR software is that what we're seeing in this video

from Brics Conference 2017?

Is this the fluency, with in this case a 70GB model incl Point Clouds/laser scans, that we'll be seeing on our own computer screens? As Erik says, this is showing VR from a company that Bricsys may well be buying, and I think that co was named during the Conference.
