Three-dimensional mesh graphics with Gmsh

Christophe Geuzaine and Jean-François Remacle have authored a graphics utility known as Gmsh.

Some of the available Gmsh documentation includes the online reference manual and FAQ. The overview section of the documentation mentions a number of possible applications for Gmsh. As with most graphical software, the screenshots give you a good idea of the software's capabilities. Some interesting electrical, mechanical, and fluid engineering drawings are included.

Version 1.44 of Gmsh has been released. Changes include new documentation and PNG support, see the VERSIONS file for more information on the project's history.

Gmsh is a cross-platform project, it runs on Linux, various flavors of UNIX, and Windows. Gmsh has been licensed under the GPL, downloads are available here, tarballs and RPMs are available. Dependencies include the OpenGL libraries, GSL (>1.2), and FLTK 1.1.X.

Filters in Apache 2.0 (O'Reilly)

Geoffrey Young writes about Apache 2.0 and mod_perl on O'Reilly. "One of the more interesting and practical features to come out of the Apache 2.0 redesign effort is output filters. While in Apache 2.0 there are all kinds of filters, including input and connection filters, it's output filters that are most interesting to me - mostly because 2.0 discussions make a point of saying that it's impossible (well, really, really hard) to filter output content in Apache 1.3, despite the fact that mod_perl users have been able filter content (to some degree) for years."

TAG: Fragment Identifiers, Subsets, and Metadata (O'Reilly)

Kendall Grant Clark covers the latest progress from the W3C's Technical Architecture Group (TAG). "For a geeky journalist, or for anyone who cares about the infrastructure of the Web broadly conceived, watching the TAG can be an incredibly efficient use of one's time. Some of the most engaging, vital technical issues regularly fly over the TAG's transom--often in volumes which, or so I have suggested in the past, threaten to swamp TAG members. In short, if you want to take the technical pulse of the Web, surveying the lines and directions of its future development, watching the TAG at work is ideal."

GnomeDesktop has an announcement for a new release of the Bitstream Vera Fonts. "There are four monospace and sans faces (normal, oblique, bold, bold oblique) and two serif faces (normal and bold).

However, during the course of researching, I realized that it was turning out to be not so introductory after all. So you'll have to wait another month for that. There are several key elements and attributes that are slated to be dropped from XHTML 2."
