BRL-CAD 7.20.0
----------------------------------------------------------------------
--- 2011-05-27 Release 7.20.0 ---
----------------------------------------------------------------------
This release marks the introduction of a new CMake build system for
BRL-CAD. CMake is cross-platform build system infrastructure capable
of generating native build system logic for a wide variety of
operating systems and compilation environments. Cliff Yapp has been
diligently working on this adaptation for a number of months in order
to simplify the task of maintaining BRL-CAD on multiple platforms.
Previously, two separate build systems were being maintained: one
system (GNU Autotools) for Linux, UNIX, and BSD platforms (including
Mac OS X); and another separate system (Microsoft Visual Studio) for
Windows. The new build system supports all platforms (including
Windows) from the same build logic. This eliminates the need to
manually update multiple build systems and improves BRL-CAD
cross-platform maintainability.

BRL-CAD 7.18.4
---------------------------------------------------------------------- --- 2011-04-12 Release 7.18.4 --- ---------------------------------------------------------------------- After considerable development, this release includes the preliminary integration of our high-performance Triangle Intersection Engine (TIE) with BRL-CAD's LIBRT raytrace library. TIE uses specialized acceleration techniques for faster raytracing of triangle mesh models. TIE was experimentally developed over several years as part of BRL-CAD's Advanced Distributed Ray Tracer (ADRT) tool suite. As this is the initial integration, TIE is available but presently disabled by default. The engine optimization is configurably integrated with LIBRT mesh (BoT) raytracing and optionally enabled via settings available in RT and MGED. Initial testing of "real-world" models shows average improvements around 20-60% while individual meshes with high (1M+) face counts are rendering more than 2000% faster than before. Also included in this release is the development of a new "shp-g" geometry importer for Shapefile data. Shapefiles are a common file format for storing geospatial vector data commonly used by geographic information systems (GIS) software. Shapefiles may be imported as 2D sketch geometry that can be extruded to a 3D representation. * fixed units conversion bug with mged 'title' command - Bob Parker * fixed memory management crash in the dem-g importer - Richard Weiss * fixed edcolors so it retains and accepts colors again - Cliff Yapp * support for applying matrix edits to revolve primitives - Dongxu Li * fixed mged 'red' command bug on Windows - Sean Morrison, Cliff Yapp * support matrices over halfspaces within combinations - Sean Morrison * fixed archer and rtwizard startup failure bug on Mac - Sean Morrison * fixed bug starting up the Combination Editor in mged - Sean Morrison * mged 'mater' command interactive prompting restored - Sean Morrison * added pix2fb and fb2pix screenshot commands to archer - Bob Parker * fixed bug running nirt on a Windows command terminal - Bob Parker * improved wireframe updating when editing within mged - Sean Morrison * added -T bot_mintie BoT optimization options to nirt - Sean Morrison * fixed Windows display manager bug when drawing strings - Bob Parker * mged command-click zoom binding for one button mice - Sean Morrison * removed 'txyz-pl' utility tool in favor of 'xyz-pl' - Sean Morrison * new shp-g importer for Esri Shapefile geometry files - Sean Morrison * new 'rt_bot_mintie' option for triggering TIE BoTs - Erik Greenwald * integrated optimized TIE BoT raytracing with LIBRT - Erik Greenwald
BRL-CAD 7.18.2
---------------------------------------------------------------------- --- 2010-12-07 Release 7.18.0 --- ---------------------------------------------------------------------- This release includes the initial release of a new Bag of Triangle (BoT) editing interface for MGED and Archer. Nicholas Reed developed the new graphical user interface (GUI) in order to consolidate the numerous BoT editing commands and processing steps into one unified easy-to-use interface. The new GUI grealy simplifies BoT processing steps and can save modelers considerable time. * ported benchmark suite to Windows (requires 'sh') - Erik Greenwald * improved NURBS wireframes with interior surface lines - Keith Bowman * additional NURBS raytracing robustness improvements - Keith Bowman * removed pl-sgi plot tool - Sean Morrison * expanded rtarea documentation with examples and detail - Cliff Yapp * improved support for unlimited object counts in mged - Sean Morrison * fixed 'erase_all' behavior so 'who' gives correct lists - Bob Parker * fixed idents, solids, and regions output - Bob Parker * increased performance of facetization and export - Sean Morrison * fixed NURBS raytrace bug grazing nearly flat surfaces - Keith Bowman * fixed infinite loop bug converting to NMG and BoT - Sean Morrison * improved Windows installer desktop shortcut creation - Bob Parker * fixed running mged external tools (e.g., rt) after 'cd' - Bob Parker * fixed 'pnts' point cloud primitive memory access bug - Richard Weiss * new BoT editing interface for mged and archer - Nicholas Reed * fixed crash during BoT decimation - Nicholas Reed * improved robustness of CSG boolean tree processing - Sean Morrison * improved loading of Pro/E export plugin on Windows - Bob Parker * added ray bundle shooting capability to rtshot - Keith Bowman * improved robustness of facetization and export - Richard Weiss * cleaner logging of facetize command BoT failures - Sean Morrison * removed 'query' command line prompting tool - Sean Morrison * increased optimized package run-time performance - Sean Morrison * fixed crash when raytracing multiple frames - Keith Bowman * fixed mged zap crash while using preview - Keith Bowman, Bob Parker * added ability to toggle mged status bar via .mgedrc - Rob Shinn * new mged 'bot' command for accessing BoT properties - Nicholas Reed
