Release Notes: This is the alpha release unveiling of Archer/MGED, a preliminary interface update to BRL-CAD's graphical geometry editor. Some highlights include 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, a level of detail wireframes, and NURBS shaded display support.
Release Notes: MGED has a powerful new 'search' command that is very similar to the UNIX find command but specifically tailored to geometry hierarchies. This release also provides a preview of many documentation improvements to come with the start of a new command help system within MGED. Other developments include numerous improvements to the Pro/E export plugin, the height field (DSP) primitive can now be exported to other geometry file formats, and much more. The INTAVAL importer is now fully integrated into BRL-CAD and included in the default install too.
Release Notes: This version is the most feature-filled backwards-compatible release to date, providing more than 75 new features, bugfixes, and other enhancements. More than two years effort has produced extensive enhancements to the Windows port including many bugfixes, more of the BRL-CAD ray-trace applications, converters, and much more. There is a new geometry importer for the INTAVAL geometry format. This release returns the "clone" command to mged, has various Tcl/Tk dependency enhancements, and has more editor enhancements.
Release Notes: A major productivity enhancement introduced in this release is tab-completion in 'mged'. Also included is a major change to the default behaviors of the ray-tracers and framebuffer tools where the windows will now linger by default. Similarly, Z-clipping is now disabled by default in 'mged'. Bugs were fixed in a variety of tools including in 'benchmark', 'dbconcat', 'mged', and 'rt'. The output precision of 'nirt' was increased for improved geometric interrogation. This release also adds a new 'beset' tool that uses evolutionary computation to detect geometric shapes.
Release Notes: This release marks the conversion of all of BRL-CAD's GPL sources to the less restrictive LGPL. The documentation has been changed from the GFDL/GPL to a BSD license. Codewise, this release introduces numerous updates to several core dependencies including Tcl/Tk 8.5, libpng, blt, and zlib; improvements to mged, pixcmp, and g_qa; and several bugfixes in the geometry converters, raytracers, and the mged geometry editor.
Release Notes: This release has a Windows port. It includes a new graphical solid modeling tool called Archer. Other enhancements include new sample applications demonstrating the capabilities of the libpkg networking library, in-memory geometry database processing, reshooting of rays from analysis codes, and the librt polynomial root solver. The MGED modeler acquires a few new commands, including reid and remat, that assist with the assignment of region and material identifiers.
Release Notes: This release provides a new quantitative geometric analysis tool, g_qa, that computes mass and volume among a variety of other values more efficiently than before. There's also the addition of a new high-performance geometry visualization tool called ISST, included as part of the ADRT triangle-based tool suite. Build support enhancements abound, as well as an improved testing framework and relocation support. Several bugs were identified and fixed, and support for SGI button and dials hardware is reenabled.
Release Notes: This release includes the addition of the Interactive Shot Selection Tool for real-time ray-tracing geometric visualization. The tool will take advantage of clusters and SMP hardware similar to RISE, providing a master job manager, a slave compute daemon for network distributed processing, and a client for interacting with and viewing the models. New options were added to the rt, rtedge, and rtxray ray-trace tools. A beta of a geometry analysis quality tool, g_qa, is now available. There are also improvements to the fast memory debugging as well as several bugfixes.
Release Notes: This release includes many significant feature enhancements, including the addition of an impressive high-performance triangle path-tracer, a completely rewritten "rtarea" tool for computing exposed and presented geometric surface areas, benchmark suite enhancements including the installation of a new "benchmark" tool for performance testing, the inclusion example BRL-CAD geometry databases during installation, a new installation filesystem organization that supports common package distribution systems, and several bugfixes and other improvements.
