BRL-CAD
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.

Recent releases
- 02 Nov 2011 22:56
Release Notes: This release provides several dozen major feature enhancements and fixes. Support for NURBS continues to improve with better STEP import, ray tracing fixes, better wireframes, and numerous robustness improvements. MGED/Archer continues to approach alpha status with support added for interactive pipe editing, improved visualization, new mesh healing capabilities, and more. After many months of effort, the OBJ importer receives a comprehensive overhaul improving polygonal mesh import. There is a new exporter to the DOT format used by Graphviz for graphic visualization of geometry hierarchies.
- 11 Jul 2011 06:29
Release Notes: This release marks the introduction of a new CMake-based build system. Improvements continue on geometry conversion and tessellation to polygonal formats. Progress was made merging MGED and Archer for an upcoming combined alpha with numerous command improvements, bug fixes, and interface enhancements. Experimental enhancements to BRL-CAD's rending system are also under development in support of programmable shaders.
- 12 Apr 2011 21:33
Release Notes: This release includes numerous bugfixes and feature enhancements to MGED, geometry converters, image processing tools, and more. This release includes the initial (yet phenomenally impressive) integration of the high-performance Triangle Intersection Engine (TIE) with BRL-CAD's LIBRT raytrace library. There is a new geometry importer for Shapefile data, and the revolve primitive receives support for transformation matrix editing.
- 10 Feb 2011 01:13
Release Notes: The biggest change provided in this release is support for reading older (platform-dependent) binary v4 geometry database files regardless of their originating platform. MGED receives several changes, including a fix for a bug that was causing text edit commands to fail. MGED will now also display attributes sorted by name for improved readability. There were numerous platform integration and usability enhancements for Debian, Ubuntu, Fedora, and other Linux platforms, including new desktop icons, menu items, MIME type associations, and much more.
- 09 Dec 2010 15:04
Release Notes: This release further improves support for NURBS raytracing and with raytrace robustness improvements and better wireframe display. MGED improvements include fixes to the "nirt", "ident", "solids", and "regions" commands. The "rt" command can now output in the PNG format. NMG/Bot tessellation robustness has improved and Spanish versions of all 16 MGED tutorials are included.

Brian2009,
That is probably because the .deb file is incredibly old. That is a contributed release that we don't directly maintain and nobody has stepped forward to update the .deb file for Debian users.
I would recommend downloading the latest source distribution and compiling BRL-CAD yourself. There are pretty extensive instructions in the INSTALL file.
Cheers!

Can't find glibc_2.4 in Debian
Hi,
I really appreciate all the help that these forums has provided. Now I have a question:
I can run brlterm, but when I try running mged or any of the other functions for that matter it says
mged: /lib/libc.so.6: version "glibc_2.4" not found (required by /usr/brlcad/lib/librt.so.19)
As I understand, Debian doesn't have a glibc_2.4, but when I do an "aptitude search glibc" I have many versions of it installed, including 2.3.6-2 and 2.7-1.
Question: should I seek out a version 2.4? (Apt-get doesn't find one) Can I get Brlcad to recognize the libs I've got?
Any assistance would be appreciated. Thanks again for all the help!

The binary distributions of BRL-CAD expect to be installed in
/usr/brlcad so depending on your version of tar, unpacking
the tarball will either result in placing the files in /usr/brlcad
off your root or in a usr/brlcad directory in your current
directory. If it's the latter, you'll need to move the usr/
brlcad directory to /usr/brlcad in order for the modeler to
work correctly.
As for the rest of the problems you mentioned referring to
machinetype.sh, setup.sh, etc -- you're reading old
installation steps for installation from a source distribution.
Once you copy the installed files to /usr/brlcad from a binary
distribution and add /usr/brlcad/bin to your path, you're
"done". The 7.4.0 release now installs more up-to-date
installation instructions that includes steps for both binary
and source installations. You can view this file here:

Re: BRL-CAD
Sorry, but even if I read some description about this software I can't install it! Well I download the latest version (7.2.6) for linux, I read The html instruction but I find something of different.
First of all when I untar the **tar.gz it create a director where I download the package named /usr/brlcad.. and under this I find a lot of others folders.
First step I lauch sh machinetype.sh -v (fortunatly I find this under /usr/brlcad/bin.
Than I should run "sh setup.sh" that I can't find anywhere.
I should run "sh gen.sh all" that I can't find to and identical for "sh gen.sh install".
because I don't understand how I can install it can someone help me?
I have a linux redhat (CENTOS 4.1) box.
I think to start to create a /usr/brlcad/cad directory where I copy everythng I untar, or I can copy what I untar under /usr/....
Thank you all
Re: Binaries for Win32
There is a beta build of BRL-CAD available for developers
only at this time, and more specifically only to developers
that received the 6.x release keys through the former non-
open-source agreement. Work is presently under
development to improve the Windows support of BRL-CAD.
When it's ready, an announcement will be sure to be posted.
Join the brlcad-news mailing list (sf.net/projects/
brlcad) if you would like to get notification of that release.
