PDF-based presentations with 3-D effects
,----[ Quote ]
| Both PDFCube and Impressive are works in progress, with some ways — and, at
| the current rate of development, perhaps some years — to go before their 1.0
| releases. However, in the current versions, PDFCube has the superior basic
| engine, while Impressive allows users the greater control. Despite PDFCube's
| lack of options and Impressive's mediocre OpenGL support, both are worth
| keeping at least an occasional eye on.
|
| In their separate ways, both demonstrate that, contrary to what many desktop
| users seem to assume, command line applications are not just archaic
| remnants. You need time to enter all the options in a command line
| application, but, if you take the trouble to familiarize yourself with the
| applications, you may find their controls easier to use than the cluttered
| editing windows of a desktop application like OpenOffice.org Impress. Far
| from being outdated, applications like PDFCube and impressive are practical
| demonstrations that command line applications can be both modern and
| innovative.

3D graphics are 100% free software 3D graphics are 100% free software

| A few months ago, SGI released a new version of the SGI Free License B. With
| that change, a lot of code used to provide 3D graphics on GNU/Linux systems
| was now free software. To make sure that all the code was free software,
| however, a few developers who worked on code released under a related
| license, the GLX Public License, needed to grant us permission to release
| their work under the new terms.

OpenCL and OpenGL take on DirectX
,----[ Quote ]
| OpenGL is now more competitive with DirectX than ever. Microsoft's stumble
| with Vista and its DirectX/Direct3D version 10 has also helped to stall its
| momentum in the market. Microsoft plans to add OpenCL-like support for GPGPU
| computing into DirectX 11 in Windows 7, but Apple's OpenCL, which is designed
| to work closely with OpenGL code, will arrive first and with broad industry
| support. Apple has also released OpenCL as a royalty-free, open standard
| anyone can implement on any platform.

NVIDIA 180.08 Beta Driver Adds In OpenGL 3.0
,----[ Quote ]
| Less than a week after releasing the NVIDIA 180.06 Linux display driver,
| NVIDIA has released a new set of beta drivers for their supported alternative
| operating systems. NVIDIA has released the 180.08 driver, which adds in
| OpenGL 3.0 support and contains fixes for their new video acceleration API.

NVIDIA Delivers Beta OpenGL 3.0 Linux Driver
,----[ Quote ]
| The OpenGL 3.0 and GLSL 1.30 specification were released back in August
| during SIGGRAPH 2008. Just days later NVIDIA had delivered a beta driver for
| Windows that added OpenGL 3.0 functionality, but Linux, FreeBSD, and Solaris
| users were left in the dark. Two months later though NVIDIA has now published
| a beta Linux driver that implements most of the latest GL/GLSL specification.

SGI Further Opens Its OpenGL Contributions

SGI relicenses OpenGL: "A huge gift to the free software community"
,----[ Quote ]
| After nine months, an open secret can finally be acknowledged: The OpenGL
| code that is responsible for 3-D acceleration on GNU/Linux, which was
| released by SGI in 1999, has been running on licenses that were accepted by
| neither the Free Software Foundation (FSF) nor the Open Source Initiative.
| Today, however, the FSF has announced that the licenses in question, the SGI
| Free License B and the GLX Public License, have been rewritten after months
| of negotiation between the FSF and SGI. The problem is now resolved, and the
| result is a code contribution that the FSF ranks as one of the greatest given
| to the community by a proprietary company.

Thank you SGI, for freeing the GNU/Linux 3D desktop!
,----[ Quote ]
| In January of 2008, software code at the heart of GNU/Linux 3D applications
| was discovered to be non-free—a potential disaster for free software
| advocates hoping to see advanced graphical acceleration now common on modern
| operating systems.
