BRL-CAD is a powerful cross-platform open source combinatorial
solid modeling system that includes an interactive 3D solid geometry
editor, a network-distributed symmetric multiprocessing (SMP)
high-performance ray-tracer with support for rendering and geometric
analysis, image and signal-processing tools, a system performance
analysis benchmark suite, a flexible geometry scripting interface,
and a high-performance geometric representation and analysis library.

7.38.006 Jan 2024 16:45
minor feature:
This major release of BRL-CAD introduces significant improvements to
the robustness of the facetize command by leveraging the Manifold
library for boolean evaluation of meshes. Facetization is an operation
that converts boolean CSG hierarchies to evaluated triangle meshes,
commonly used as a preliminary step in geometry export. As an
example, the following results show before-and-after differences when
processing high level assemblies in BRL-CAD's example geometry files:
success, old: 88.9 (249 of 280) Time elapsed: 7256 seconds
success, new: 98.9 (277 of 280) Time elapsed: 1044 seconds
