Reduce Ads with Firefox

Posted by Kaya Kupferschmidt • Thursday, September 15. 2005 • Category: General
Yesterday while I was browsing through the internet, it finally happened after a visit to Spiegel Online, the online version of a popular German news magazine: I couldn't stand the advertising banners any more, they were simply eating too much space on the screen and downgraded the experience by a massive amount.

So I googled arount and in some seconds, I found two very useful tools for Firefox: The Adblock Project which is a simple but powerful adblocker for the Firefox browser and the Adblock Filterset.G Updater, which fetches the newest filterset from the internet.

After installing these two tools (which are installed on a per-user basis), most of the disturbing ads disappeared from the webpages - and pages load much faster, (although I already have a 6 MBit connection, but it seems that many ad-servers simply can't provide their unwanted content fast enough).

Finally - a new demo.

Finally I decided to publish a new demo together with the current version of magnum, although the scene graph is still not in a working condition. But there are so many new features and bugfixes that I thought it would be a good time to release at least something.

The demo itself is using the long awaited EXT_framebuffer_object extension from OpengGL for creating cubemaps for the reflections of each sphere rendered.

But there are so many new features in magnum, including new model loaders (LWO, MD2, MD3, MDS, PLY, OBJ), vertex and bone/skeleton animations (finally!) plus a lot of small changes and additions that make life easier. Some more demos coming soon, including animations!

On Quaternions and more...

Posted by Kaya Kupferschmidt • Monday, September 5. 2005 • Category: OpenGL
One important mathematical object for animating 3d graphcis objects are the so called quternions. It is not easy for beginners to understand the idea behind quaternions and why they work better than Euler angels. But for those interested in this subject I found to nice links, the first goes to a general geometry and graphics page which inculdes many other interesting tidbits: EuclideanSpace - building a 3D world.

The second link called Understanding Slerp, Then Not Using It is a rant about the important slerp operation. Here the author points out that slerp may be a very precise interpolation but that it is overkill for most applications and a much simpler normalised linear interpolations will do the job just as good.

So you can expect a new release of magnum soon which will include a lot of new features and more importers (PLY, LWO, MDS, MD2, MD3) plus vertex animations and skinned bone animations. So I haven't been lazy during the last weeks, but there are still some small things missing plus the scene graph module is defunct at the moment.
