I actually am at a windows machine at the moment. I think I probably need a newer quicktime, or something. I am finding that a lot of sites are starting to use only files that work with Windows Media Player 7, but that requires Windows 98, and this is only a 95 machine. It is new enough and fast enough, but the corporation decided to stay with 95 till they jump to 2000, so I'm stuck.
Yeah, it looks like nice eye candy, but I think that it could distract game play. Of course, we won't really know until it is out.
Also, I kinda pictured it as something that would have a darker and more aggresive shading style than those screen shots indicated. The movie wouldn't work for me, unfortunatly.
This does make me want to get a new n64 and a zelda cart to play it again.

This could be really interesting. Should Zelda be realistic or cartoony?
It started as cartoony out of nescesity of being a sprite based game, and while moving to 3D, it still maintained what I believe to be a somewhat intentional cartoonish appearence. So, in a way this is going back to basics.
But, so far I haven't been impressed with realtime cell shaded games. They just don't seem right, and the graphics have tended to be rather distracting in the past.
First, OpenGL is not overkill for 2D. High end 2D software on SGIs (like paint programs and compositing/effects software) has been written using GL for years. Further, I believe GL has color correction. I'm not sure what you mean by compression, but there is texture compression (sorta), and through the imaging extensions, I think there is support for other forms of compression. Font's aren't really supported under GL as such. If you represent them as lines or bitmapped textures, your fine, though not as easy.
But really, it isn't an either or thing. GL is really low level, and the whole glory of Display Postscript (and presumably DisplayPDF) is that it is quite high level, and handles fonts, and string displaying, and curves, and fills, etc. The ideal would be to lay DisplayPDF on top of OpenGL.
Hmm, no one seems to have yet said "How about a beowulf cluster of these things!" yet. People are starting to slack around. Get to work anonymous cowards!!!
You have to give up the GUI (sorta), but it is doable. Actually, XFree can be relicensed as GPL, so GNU could fork it for their own, but instead the publicly encourage people not to make GPL only XFree drivers.
In this case, linux isn't quite as much of a niche market. I haven't bought any Loki games because the ones I might like need a 3D accelerator, and while I do have one, I have spent many hours trying to get it to work with no success. From what I hear at school, it sounds like numerous other people have similar problems.
On the other hand, playing back video works pretty well. DVDs work fine with videolan. Divx playback systems perform fine when they work at all. From what I've seen, it is nowhere near as hard to get video playback to work as 3D acceleration is. So, perhaps linux users would be more likely to participate. I still might not on matters of priciple, and not having a credit card.
I really am beginning to think that Stallman might tremendously help himself if he got a hair cut and a personal image consultant. Way to many people dismiss him as being a washed up hippy.
Down here, dulies refer to having 4 tires on the rear axel instead of 2. I don't know about Canada, but I would think it would be the same as down here.
Anyway, around here, I keep seeing this guy in a Chevy (a big one, maybe a silverado?) dulie that has been lowered to about 2-3 inches off the ground. Every now and then I'll a big truck that's been lowered like that (Dodge Rams seem to be the most common), but this one with the dulie looks the stupidest. Although, to the guys credit, the other day I realized that it wasn't really a dulie. It has the flares off of a dulie truck, but it looks like it is just a regular axel with really wide tires on it.

Bzzt. Apple has never, and never will make G3, G5, or any other PowerPC chip. Those chips are only made by Motorola and IBM.
First, you are aware that DirectX does more than just graphics right? If you are writing a game on windows, the only reasonable way to do sound, and control input are through DirectX.
Now, what I want to know is, are you trying to tell us that Quake3, Unreal Tournament, Halflife, and Counter Strike are no longer for sale? Those are all games that not only support OpenGL, but also work best in OpenGL if there is an option (except Unreal Tournament which works best using Glide).
One of the biggest problems with OpenGL, is that Microsoft has been sabatoging it ever since Windows 95. For instance, for you video drivers to be Microsoft certified, they have to fully and properly support DirectX, including Direct3D. OpenGL drivers on the other hand aren't required, and when they do exist, they could just plain not work, and still the card and drivers could be Microsoft certified. This is why there where so many QuakeGL implementations of OpenGL floating around a few years ago.
I love my Palm IIIxe, but there are two things I wish it could do and many tweaks I'd like to see in the software.
The first thing that would be really helpful would be if it could read memos and other things to me. I often store directions to locations as memos, and I'd like to be able to hear the next line without having to look at the screen. The second thing is I would like voice recognition so that it could take memos and notes from me while I drive.
These are both things that mainly require a faster CPU, although I wonder if maybe a dual processor system wouldn't be better (a slightly faster CPU, and a dedicated DSP chip) for heat output reasons.
Also higher resolution (supported by non standard extension on the CLies) would be wonderfull for the eyes.
The file system seemed to be pretty innovative to me. I liked the attributes system. However, other than that, yeah, I pretty much agree. They just made a solid, fast product, not a major league innovative one.
I spent a long time hoping that they would suceed, but gave up after never getting an GL hardware support other than fullscreen voodoos. All I wanted was some simple 3D acceleration (GL programming is what I do. So, a platform must have good Gl for me to really support it).
If Newtons had come out Palm sized, then Palm would never have developed the pilot. They only developed it because no one else was making a decent handheld. Before the pilot, they just sold software to other handheld manufactors.
Be started out on a chip from AT&T called the Hobbit (http://www.bebox.nu/beboxdev.php). First prototype used 1 hobbit. The second used 2 hobbits and 3 3210 DSPs (the AV in the Quadra AVs, plus also used in numerous Photoshop accelerator boards). This would have made for a really, really cool system. But, then the Hobbit was canceled.
That is when Be moved to PPC. The PPC BeBoxes were actually kinda crummy. They have no L2 cache, which hurt them, and they used 603 chips which also weren't so great. The only reason that people didn't realize the boxes sucked (well, sucked might not be the right word, since they were nicely designed, and the geek port was cool, but there were too many sacrifices made) was that the OS was so much radically better than anything else in speed and responsiveness that most people didn't notice.
That is somewhat true. However, when I set my desktop to 32bit color, where are these alpha chanels being used? Maybe if windows or linux supported truly transparent windows we would be using 32bit color, but for the most part those extra 8bits might as well be padding.
I heard somewhere that Photoshop can use a 32bit display to accelerate redraws of multilayer images (letting the hardware sort out the transparency). It would be possible using say OpenGL, but I'm not that windows will do this, even in 32bit mode. I really don't have any clue about whether or not the mac would.
OK, in profession circles, we don't say 24bit, we say 8bit (ie, 8bits per chanel, 3 chanels).
Anyway, if we can't tell the difference between 8bit color and higher color depths, then way to so many professional video rigs record and play back in 10 bit color, and why was Shrek recorded to film in 16bit color?
The answer is that when an image emphasizes one color over another, banding can occur. Also, it isn't hard to find instances where detail was compromised by contrast in digitial images. Looking around on the sections about digital cameras on www.photo.net will discuss this issue somewhat.
It should be pointed out that in DirectX, there is one standard way to do it, but if that standard doesn't exist, then it can't be done.
OpenGL is more flexible in this way. The only problem is that some things need to be migrated from vendor to multi vendor extensions faster. As soon as both Nvidea and ATI have a new feature, it is time for the Gl commitee to hammer out an initial draft for a multi vendor extension I think.
Dude, understand that I love OpenGL. I use GL for everything. I think that the only proper way to write a word processor is with GL (or a toolkit that sits on top of GL). One of these days I'm going to rewrite GTK to sit on GL (with only enough code to manage the glx stuff).
That said, extensions only work if everyone agrees on them. The texturing extensions (OpenGL 1.1, brought into the spec in 1.2 I believe) were fine because they were pretty much the same from platform to platform. Vertex shading on the other hand, no one seemed to agree on (in the OpenGL 1.2 era). I'm not sure if Vertex shading is more standardized in the new version or not, since the file is being extremely slow to download.
I think what OpenGL needs to to keep the same pace with the main spec, but to have a seperate commitee that sets extension standards and moves more quickly. Of course, other companies should also be allow to do propriety extensions if they want to still.
