----------------------------------------------------------------------
BRL-CAD's ray tracing support for NURBS boundary representation
geometry objects continues to be developed towards providing a robust
foundation for supporting multiple-representation geometry. This
release includes several NURBS ray tracing bug fixes, robustness
improvements, and trimming enhancements.
MGED receives a lot of attention towards improved stability with
numerous troublesome bugs getting fixed (e.g., "the Mac input bug"),
restoration of behavior for various introspective commands, and
continued feature integration with Archer. MGED's wireframe display
gets a substantial 5x-10x performance improvement for non-Windows
platforms while MGED on Windows now supports 64-bit releases and
restores command-line scripting support.
Archer gets a user interface facelift with the introduction of a new
geometry browser, list view, buttons, and much more. As Archer
approaches feature parity with MGED, it gets closer to an official
alpha release status as BRL-CAD's next generation geometry editor.
