Fending off spammers
Sunday, January 21, 2007 | Permalink

If you visited this site this morning or yesterday night and found that you was redirected to another site, please do a virus scan on your system.

Apparently a spammer was able to squeeze in a javascript into his name tag in the comments. Unfortunately, I didn't have the security check for the name field as I have for the comment field. Thus the script was included in the regular html code, causing all visitors to the main page to get redirected to the spammer's site. As I got redirected this morning my antivirus program immediately alerted me as I arrived at the spammer's place and it tried to plant a virus on my machine. For those of you that don't have a antivirus program or don't have it configured to continuously guard your files, you probably got infected if you went there.

I have now fixed the security hole and as a further step to fend of spammers you'll now have to enter a code when you comment. This should be very quick and not be a problem for regular posters and hopefully block most spam bots.

New textures section
Sunday, October 29, 2006 | Permalink

Recently I've renewed my interest in photography, in particular after upgrading to a new digital camera. One of the things I've played with a lot is creating cubemaps from photos, something you've been able to see in my last couple of galleries. The versions I've uploaded there are only small resolution though intended for interactive viewing on the web. The source cubemaps I've rendered out on my computer are typically much higher resolution than that though. Also, for the galleries I've primarily selected cubemaps that are interesting in the context of the gallery, but there are a whole bunch of other cubemaps I've made that hasn't made it into a gallery. Since there are very few good cubemap resources on the web (at least I'm not aware of too many, and the ones I know have only computer generated environments), I thought I should do that.

I've added a new Textures section to this site, and you can see the link in the menu on the left. I've uploaded 7 cubemaps so far and they are all high resolution ( 2048x2048 ).

I went home to Sweden for a couple of week in early September, so here a new gallery with the pictures from that trip.

New dynamic lightmapping demo
Sunday, August 20, 2006 | Permalink

As you've probably noticed, there haven't been many demos lately, mostly due to lack of time. But now I've finally finished this project that's been laying around for a while. It's generating lightmap dynamically on the GPU. On the first run it will generate four position maps, so it may take up to maybe 10 seconds to load. Later runs will start much quicker.

Enjoy!

New gallery
Friday, August 18, 2006 | Permalink

I've added another gallery with pictures from this summer. This one also includes an interactive element. I've made a java applet using OpenGL to render cubemaps. I've stitched together a bunch of cubemaps from a bunch of photos in all direction, and I've included a few of these in the gallery.
