As you may know, BRL-CAD is an open-source, cross-platform solid modeling system that has high-performance ray-tracing for rendering and geometric analysis, it includes interactive geometry editing, image and signal-processing tools, a system performance analysis benchmark suite and libraries for robust geometric representation.
The latest version available is BRL-CAD 7.28.0, which comes with changes.
Installation instructions:
The latest version of BRL-CAD is available as deb packages via sourceforge, so installing in on Ubuntu 18.10 Cosmic Cuttlefish, Ubuntu 18.04 Bionic Beaver and derivative systems is easy.
You need to download the package matching your architecture and to install it via the default package manager. I prefer gdebi because it also handles dependencies.
