For those that don't know, Mesa is an open source implementation of the OpenGL API. It's a key component of the open source graphics stack that powers Linux desktops, as well as many other operating systems. Mesa is the default OpenGL implementation for most Linux distributions and is what makes hardware accelerated OpenGL work "out of the box" on those systems. For this reason, the version number of OpenGL it supports is important if you are developing cross-platform OpenGL applications because it is the baseline version that you can target to get the widest audience.

The Mesa developers are currently preparing the next release.

If you want to get started with OpenGL in web applications using the new standard WebGL, one good way to try your ideas is using webglplayground where you can edit your JS code on the fly and see the results immediately. It is bundled with some libraries to make your life easier.

The applications you develop there can even be hosted on their site and embedded in your own webpages. Looks promising!

After getting past the iOS specific hurdles in lesson 01, I finished lesson 02 that shows you how to create a colored triangle by using vertex buffer objects and GLSL shaders!

Go and have a look: iOS Lesson 02

One of the most frequently asked questions in the forums is why the texture loading code from lesson 06 does not compile, complaining about glaux.h not being found.

Well I finally took the time to show you how to get rid of this problem and even better, load textures from a huge variety of file formats with one line of code by using SOIL (Simple OpenGL Image Library).

So read this in conjunction with Lesson 06 for the full fledged texturing experience:

Great news: I finally finished the first lesson in our new iOS series! Have a look in the menu on the right under Mobile Tutorials.

And from today on I'll have more time to work on new lessons so stay tuned, more to come soon!

I'm happy about any kind of feedback about the lesson as well, please use the forum linked at the bottom of the lesson for that.

Go have a look!

APITrace is a graphics debugging tool for tracing and logging calls to OpenGL and D3D to allow you to debug graphics applications. It's written in QT and is entirely cross-platform and open source. I haven't had a chance to play with it yet, but the screenshots speak for themselves:

You can read Zack's announcement here, and find the source code to the application here.

For those of you interested in the most up to date OpenGL coding: There's a nice pack of sample applications for all OpenGL versions up to 4.2. It doesn't contain a lot of comments, nor does it use the features for complex effects, but they still show how to set up all the different new features! Definitely worth a look if you're using modern OpenGL...

Following on from the release announcement of OpenGL 4.2 a few days ago, AMD have just released a new driver which supports the new specification. It is a *BETA* driver and is available at the following locations:

Windows: http://support.amd.com/us/kbarticles/Pages/AMDCatalystOpenGL42BetaWin.aspx

Linux: http://support.amd.com/us/kbarticles/Pages/AMDCatalystOpenGL42BetaLinux.aspx

Yeah, I know.. I know! about time!

Some of you have found it already, but for those who haven't you can find it over at http://twitter.com/#!/nehegl

Yep, there's nothing there yet! But at some point soon I'll connect it up to our news stream so you can updates through there. Also, if you didn't already know we have an RSS feed and an Atom feed.
