TV appearance
Monday, March 9, 2015 | Permalink

Me and my wife and kids make an appearance in a documentary series on Swedish TV. The series is called "Vi ska ha barn" (roughly translates to "We're getting a baby") and the various couples discuss their hopes, fears and expectations around having kids. In our case, the angle is mostly about getting a second child, and about tackling cultural differences in the family.

Our episode is available online here (In Swedish).

Yet another 11 cubemaps

I've uploaded yet another 11 cubemaps.
And yes, I still have more in the pipeline that I haven't finished yet.

There are now another 11 cubemaps available on the Textures page. Enjoy!
I have more cubemaps ready to go, so expect more to get uploaded shortly.

I'm now a father of two
Tuesday, May 20, 2014 | Permalink

On May 9 our second son was born. 3.805kg and 52cm at birth, a bit bigger than average, but not huge like his older brother was. He's getting along very well with his older brother so far.

A most welcome addition to the Persson family.

Added WebGL preview to cubemaps
Sunday, April 13, 2014 | Permalink

A couple of months ago I replaced my old Java Applet based cubemap viewer with a new WebGL one for the pictures on this site. The obvious next step was to use it for my cubemap collection, although that required that I generate the content for that also, so it was a bit more work. Now I've finally done that work, so now all cubemaps come with a WebGL preview link (or you can just click the image) so that you can get a more intuitive and interactive view of a cubemap before deciding to download it. Note that the preview is only 512x512, whereas the full cubemaps are typically 2048x2048.

Conference appearances
Sunday, March 9, 2014 | Permalink

A bit late to announce this here now, but I'll make a couple of conference appearances shortly. First I'll participate in an "Industry Panel" at I3D in San Francisco next week discussing scalability issues. I3D is co-located with GDC, which is where I'll appear next, talking on the title Low-Level Shader Optimization for Next-Gen and DX11. If you were on last year's GDC you may have been on my talk "Low-Level Thinking in High-Level Shading Languages". This talk is on a similar theme, but focusing more on the GCN architecture that's in next-gen consoles. Hope to see you guys there!


Site update - WebGL cubemap viewer
Sunday, January 26, 2014 | Permalink

In my recently quite underutilized Pictures section of this site I have in the past used a Java applet and JOGL for OpenGL support to implement a basic cubemap viewer. That kind of worked, but the downside was of course that it relied on Java being installed, and then required the user to accept the installation of native JOGL components for his system. Fortunately, it's now 2014 and even Internet Explorer has basic support for WebGL, so I decided to upgrade this part of the site to go plug-in free and just work provided a modern browser.

So far I've tested it in Firefox, Chrome, Opera and IE11, and it works perfectly in the first three. IE11 also works OK-ish, but for some reason zooming on the scroll wheel doesn't work, and WebGL seems to go into software rendering so performance is a big sluggish, but it least it renders correctly.

To see it in action, you could for instance go here, or any other picture with a green frame around the thumbnail (green means cubemap). Please let me know if it doesn't work in your browser.
