A couple of weeks ago Google announced O3D: an open source web browser plugin for low level accelerated 3D graphics. The website for O3D project is here.

Of course this created some buzz (hey, it’s Google after all). And it is in some way a competing technology with Unity. I think it’s going to be interesting, so I say “welcome competition!”

Preemptive blah blah: this website is my personal opinion and does not represent the views of my employer, former employers or anyone else other than myself.

Unity is one of the players in “3D on the web” space. 3D graphics in the browser are in fact nothing new. Unity’s browser plugin has existed since 2005 and is now in eight digits installations count. There is VRML, X3D, Adobe Shockwave, 3DVIA/Virtools, software rendering approaches on top of Flash and so on.

In my view, major advantages that Unity has compared to O3D:

• It’s not only about the graphics. Unity has physics, audio, input, scripting, streaming, networking, asset pipeline and whatnot. O3D is only about the graphics, and at a lower level.

• Unity runs on wider range of hardware. O3D requires Shader Mode 2.0 or later hardware, so about 30% of the “machines on the internet” can’t run O3D (based on our 2009Q1 data). Couple that with lots of compatibility workarounds that we have and it’s probably safe to say that Unity is more stable and mature at this point.

• Unity is not only about the web. There’s support for iPhone, Nintendo Wii, standalone games, and with time more console and mobile platforms will come.

• Creating and improving Unity is our primary and only focus as a company. In Google’s case, O3D is just another technology in their vast portfolio.

Of course, O3D also has advantages:

• It’s done by Google! When Google does something anything, people notice immediately :)

• O3D is free and open source. Hard to beat the free price, and open source does have it’s benefits. O3D is not a “standard” of any sort right now, but it looks like Google would want it to become one.

• Only focusing on low level graphics has it’s benefits: it’s lightweight, it appeals to hackers and graphics programmers who want to be in control. Unity’s higher level is much easier and faster to use, but low level hacking can be fun.

Of course there are tons of other differences (I might have missed something important as well).

For me as a rendering guy, it’s interesting to see O3D taking similar decisions here and there (e.g. they don’t use GLSL on OpenGL either because it does not really work in the real world).

So… we’ll see where things will go. It’s going to be interesting!

Here, ryg nails it:

why would you want sound and physics when you can have sparsely clothed ninja space marine amazon secret agents riding on chainsaw-hoofed flying pink stealth space unicorns through a brightly colored dystopian african urban jungle fantasy wasteland island state populated with mutated propaganda-spewing gas mask-wearing alien nazi zombie demons that entered this island planet dimension through a hellgate portal invasion triggered by a black magic freak teleportation experiment resonance cascade accident caused by a power-hungry mad scientist wizard evil genius working for a multinational corporation conspiracy of lawyers and weapons manufacturers without morals, and all that in its proper realtime dynamically lit globally illuminated deferred-shaded parallax-occlusion-mapped ambient-occluded shadow-buffered high dynamic range silky smooth glory?

Pretty much sums up the mainstream game industry!

Unity 2.5 is finally released. In summary:

Here’s what’s new. Here’s the download page.

My 11th Unity release since I joined 3+ years ago. This is quite a crazy release that involved almost complete editor tools rewrite and lots of other juggling. Was not exactly a walk in the park, but it’s done now. Meet me at GDC in San Francisco next week and I’ll tell you the war stories (Unity booth is 5110 NH).

Here’s the obligatory source code commits graph:

18 people involved in source code, 5315 commits, 18501 file changes. Of course, svn commits do not mean anything… I’m just fascinated by graphs and numbers.

Ok, I don’t exactly like Windows Vista. But I just spent 6 months using Vista as my primary OS at work… because everyone else was using XP, and someone had to make sure everything works on Vista as well. So it was me.

In summary, Vista is not that bad.

Once you get used to changes in Explorer, different skin and so on - it’s actually usable. I think they have made some real improvements in the underlying technology, too bad they managed to “compensate” for all of that by inconsistencies and lack of polish in user interface.

At this point it’s minor quirks in UI that annoy me, but apart from that, Vista is okay. Look:

Who implemented blending of icon overlays and do they still have a job? No sir, that shield icon is not properly blended here!

Who thought it’s a good idea to make the Burn icon bright red? In 6 months, I never used it. Why is it the brightest thing in the whole Explorer window?

Try going one folder up without resorting to this drop down menu. Utilities is the current folder here. And no, there’s no keyboard shortcut for “go up” either (there was in XP, which was perfect).

And of course, the awesome shutdown menu. The two buttons - never used them. What I always use is “Shut Down” from the menu. And let’s not even talk about all the choices in the menu (no, more choices is not always better).

So yeah. It’s not stellar, it has tons of small annoyances (and some large ones - try developing web plugins with UAC on…), but it’s usable. I might have gotten used to it by now, actually.

It’s funny how one’s view on things change over time.

Back in 2002, I wrote something that would be roughly translated like “C++ amazes me more and more”. In a positive sense! And I was talking about what is Boost.Spirit now.

A reply on local game development forums I wrote today (again, rough translation): “C++ is very hard and quite a horrible language, maybe you should not use it unless there are no alternatives”.

That’s quite a change in attitude we have here!

I feel like much of C++ horrors are a consequence of “it just somehow happened” (the whole template metaprogramming thing) or as a backwards compatibility with C requirement. Or maybe not, but I do agree with what ryg says here. Let’s play the internet memes:
