----------------------------------------------------------------------
--- 2023-11-06 Release 7.38.0 ---
----------------------------------------------------------------------
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

----------------------------------------------------------------------
--- 2023-07-26 Release 7.36.0 ---
----------------------------------------------------------------------
This major release of BRL-CAD introduces significant updates to
geometry conversion support. The update includes modernization for
NURBS importing and interaction, BoT manipulation, and incorporates
many new formats for importing and exporting to BRL-CAD database
files.
The geometry conversion tool (GCV) now supports mesh importing
from: 3D, 3DS, 3MF, AC, AMF, ASE, ASSBIN, B3D, BVH, COB, COLLADA, CSM,
FBX, GLTF/GLB 1.0 + 2.0, HMP, IFC-STEP, IQM, IRR, IRRMESH, LWO, LWS,
M3D, MD2, MD3, MD5, MDC, MDL, MMD, MS3D, NDO, NFF, OFF, OGRE, OPENGEX,
Q3BSP, Q3D, RAW, SIB, SMD, TERRAGEN, X, X3D, XGL.
Additionally, GCV now supports mesh exporting to: 3DS, 3MF, ASSBIN,
ASSJSON, ASSXML, COLLADA, GLTF, PBRT, STEP, X, X3D.
This release also introduces new BoT subcommands to improve
manipulation and preparation. The subdivision "subd" command
incorporates 5 new subdivision algorithms. The "flip" command will
flip surface normals - effectively turning the BoT 'inside out'.
Lastly, the "smooth" command will smooth the BoT's topology.
* Added a point-inside-object subcmd "inside" to analyze - Cliff Yapp
* Added "flip" "subd" and "smooth" subcommands to BoT - Cliff Yapp

----------------------------------------------------------------------
With development efforts spanning several years, this major update to
BRL-CAD includes considerable progress on infrastructure for graphical
user interface improvements, geometry conversion, and physically-based
rendering. It also includes hundreds of logic and memory management
bug fixes, potential code vulnerability updates, and other issues
reported by Coverity and Clang Static Analysis.
This release also overhauls the way 3rd-party dependencies are managed
in BRL-CAD. Native build systems are now used in order for updates to
be more readily applied, to reduce maintenance overhead, and to set
the stage for the aforementioned major feature developments.

----------------------------------------------------------------------
This major release of BRL-CAD incorporates a new feature for caching
of raytrace acceleration structures used when working with explicit
boundary representation (BREP) Non-uniform Rational Basis Spline
(NURBS) objects. This will result in significant improvements to run
times when repeatedly raytracing BREP objects.
Support for terrain import has been significantly expanded with the
addition of a new Geospatial Data Abstraction Library (GDAL) based
importer to the gcv conversion tool. GDAL brings with it support for
dozens of different terrain data formats.
Also new in this release are a greatly improved graphical geometry
overlap resolving tool and support in the MGED search command for
an "exec" option which will allow users to execute MGED commands
on search results.
The MGED facetize command for generating polygonal geometry from
BRL-CAD objects has received significant attention, including the
incorporation of a "per-region" conversion mode, new conversion
methodologies and usability enhancements.

----------------------------------------------------------------------
--- 2017-06-10 Release 7.26.2 ---
----------------------------------------------------------------------
Among a variety of bugs fixed, the patch corrects a critical error in
BoT triangle mesh ray tracing. For improved performance, it also
changes the default frame buffer display behavior to fully buffer ray
tracing images instead of displaying them incrementally. A variety of
MGED commands see improvements too with 'ls' now supporting listing
objects by their on-disk size and the 'simulate' command applying
forces on objects (e.g., gravity) with greater ease. Not yet
complete, there is a new interface being developed for resolving
overlaps more efficiently, currently under development and usability
testing with select users. Lastly, a number of dependencies were
upgraded, including Tcl/Tk, in order to patch security vulnerabilities
and address portability issues.

--- 2016-08-08 Release 7.26.0 ---
----------------------------------------------------------------------
This major release of BRL-CAD culminates several years of development
effort to provide robust explicit boundary representation (BREP)
Non-uniform Rational Basis Spline (NURBS) import and ray tracing
analysis support. Compared to previous polygonal mesh (BoT) methods,
NURBS offer superior interoperability with other CAD systems, faithful
shape-preserving import, and significantly reduced model sizes. NURBS
may be imported from the ISO STEP (AP203) and Rhino 3DM file formats,
both with improved hierarchy preservation and entity support.
Unprecedented in BRL-CAD's history, this release initiates steps to
significantly reduce complexity and improve usability. Many features
are being consolidated, reorganized, and removed via BRL-CAD's
deprecation process. There are widespread documentation system
enhancements including new manual pages, improved command usage,
better help facilities, and more.
This release introduces the 'gcv' and 'icv' tools for geometry and
image conversion respectively. These plugin-architecture tools are
intended to eventually consolidate and replace all of BRL-CAD's
conversion and processing functionality into an easy universal
interface for users and application developers. GCV currently
supports import and export of STL, 3DM, OBJ, VRML, and FASTGEN
geometry as well as mesh decimation, facetization, and solidity
testing. The new FASTGEN exporter implements extensive compatibility
feature mapping for round-trip geometry conversion.
Ray tracing performance on Windows is vastly improved on symmetric
multiprocessing (SMP) multicore and multiple CPU systems. Implemented
as 'datum' objects, BRL-CAD provides new modeling support for
reference points, lines (axes), and planes. Major features still
under experimental development include NURBS Boolean evaluation, a new
marching cubes method for polygonal mesh export, rigging joints for
constrained geometry articulation, and an OpenCL-accelerated high
performance ray tracing pipeline.

----------------------------------------------------------------------
This major update to BRL-CAD comes after nearly a full year of
development. This is the alpha release unveiling of Archer/MGED, a
preliminary interface update to BRL-CAD's graphical geometry editor.
As alpha software, this new MGED prototype aims to provide functional
feature parity with the antecedent MGED interface while introducing
various changes. Included is an integrated graphical tree view, a
single window framework, drag-and-drop geometry editing, information
panels, shortcut buttons, improved polygonal mesh and 2D sketch
editing, level-of-detail wireframes, NURBS shaded display support, and
much more. Prior to upcoming beta testing where the emphasis will
predominantly be on stability and usability, this alpha status
solicits feedback from the community on capability and features.
This release also includes various improvements to BRL-CAD's ray
tracing infrastructure including CPU thread affinity locking for
faster performance, more consistent grazing hit behavior, expanded
volume and surface area calculations, numerous bug fixes, and more
robust NURBS evaluation. Following BRL-CAD's interface deprecation
policy (see CHANGES file), the Jove text editor is no longer being
bundled. Numerous converters receive robustness improvements
including the STEP, Patch, and 3DM importers.
