BRL-CAD 7.12.6 Released

BRL-CAD 7.12.6 Released

I'm happy to (belatedly) announce the release of BRL-CAD 7.12.6 with several enhancements and bug fixes. Notably, NIRT gets several new output formatting options allowing users to easily select different data reporting options without having to define their own custom configuration files. The tire tool's behavior has been improved with better data protection, more editing flexibility, and improved rendering.

MGED's dbconcat command works again without needing to specifying an affix for object names when importing geometry from one database to another. Primitive selection via the Edit menu is working again thanks to the fixing of the solid_illum bug. The pipe primitive's performance problems during raytracing, due to unnecessary memory allocations, are now fixed. The extrude primitive's handling of invalid geometry is now more robust.

Since the 7.12.4 release, the following user-visible changes have occurred:

* renamed mged binary command to bo for binary objects
* fixed bug that caused remote framebuffers to fail
* add w option to tire to allow disabling wheel generation
* tweak tread 2 in tire tool; avoid artifacts on tread wall
* fixed mged 'dbconcat' hang when not specifying an affix
* fixed primitive selection solid_illum bug in mged
* fix bug in tire tool's geometry causing 'nicks' in tread
* increased raytrace performace of pipe primitive
* fixed bugs handling invalid extrude objects
* fixed dependency bug in library pkg-config files
* platform installers now use a more consistent naming convention
* added new -c character option to the loop command
* tire now checks for files instead of overwriting
* add new nirt formatting options, -L listing option
* fixed nirt's dest cmd's handling of file name string
* modified mged nirt command to include air in results

Special thanks to Cliff Yapp, Sean Morrison, Bob Parker, John Anderson, and Dawn Thomas for their contributions made in this release.

This is a backwards-compatible source-only developer release. See for the full list of changes for each release.
