---------------------------------------------------------------------- --- 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. * mass-deprecation of 121 command-line utilities -
