Initial WebGL Support Lands In WebKit

appleprophet writes "WebGL is an upcoming standard from the Khronos Group, the same standards body behind OpenCL and OpenGL ES. It defines the use of OpenGL in websites using the standard canvas element. In other words, websites will be able to render hardware accelerated, 3D graphics natively inside of a web page. In the last week, WebKit, the rendering engine behind Safari and Google Chrome, has added initial support for WebGL, which means it probably won't be too long before Macs and iPhones everywhere get OpenGL web apps. This could have big implications for gaming. HTML5 has steadily been encroaching on desktop applications' territory, but I don't think many people expected browser-based, hardware-accelerated graphics this soon."

Ads

[bcmm]

While I'm sure there are some great uses for this, it also sounds like a way to serve even more resource-hungry adverts than they can with Flash. Furthermore, if this became widespread in situations not really requiring it, a decent graphics card could essentially become a requirement for web surfing.

I don't see how this is any different than the current situation with Flash.

Flash is resource hungry, and plays annoying ads in both 2d and 3d, with sound. So the situation is presently worse. Even if WebGL includes audio (or perhaps in the future there will be WebAL, etc.), the situation is presently worse given how problematic Flash is.

Having seen some of the things Apple (and others, but it's really Apple that's pushing it at this point) is doing with HTML5, everything that can be done to replace Flash is a good thing. Even if it means the same annoying types of ads as now, at least they'll have less of a performance hit, and they won't be tied to a single program that is constantly plagued with security issues, has performance issues, crashes so often that Apple and Google sequester plug-ins/windows/tabs because of it, and whose updater is annoying and tries to push additional toolbars which no one wants.

Just as Flash served to kill off pretty much all the various and annoying plug-ins you had to download to make full use of the web, and replaced them all with a single plug-in to rule them all, HTML5, with things like canvas, the video tag, and WebGL, is looking to do the same to Flash--replace it with something better.

Why?

[Darkness404]

Why is this necessary? There are some positive uses for it (such as getting us out of dependence on proprietary technologies like Flash) but a lot more negative issues. For one, this will add even more vulnerabilities to browsers which seem to already have loads of them. And for another the web should be accessible for -everyone- from the low-end netbook to a Core i7, and even older systems should be able to browse web. Already many sites are unusable without a recent version of Flash, we don't need extra hardware as requirements to view sites. Yeah, we all know that they should do it in HTML and that will still stick around, but how many of us have encountered sites built entirely in Flash? Or have a requirement of Flash for simple things like navigation? While some things obviously need Flash (such as Homestar Runner because they are Flash cartoons) others use Flash for no real reason. Currently most platforms have Flash or will be getting it. But adding a high-end graphics card to a computer just to view the web? Thats just a bit ridiculous.

Because when this takes off (a few years from now), it might even invalidate Flash as WebGL also mean accelerated 2D and would be more performant in general then 2D Flash, and it could possibly free us from closed-source and proprietary Flash in the long run.

There are already a lot of ways we could get rid of Flash, if people would stop using it. After all, Flash is mostly used for vector graphics (we've got SVG), interactivity (we've got AJAX/DHTML), and audio/video (we've got the audio and video tags).

For one, this will add even more vulnerabilities to browsers which seem to already have loads of them.

So does every useful feature. I'll bet money that the first serious vulnerability is in a driver, not a browser.

And for another the web should be accessible for -everyone- from the low-end netbook to a Core i7, and even older systems should be able to browse web.

OpenGL can be implemented in software.

And you lost that argument already with Flash. When there are one or more video ads on many pages I visit, I doubt low-end netbooks are doing well.

Yeah, we all know that they should do it in HTML and that will still stick around, but how many of us have encountered sites built entirely in Flash?

The fact that technology can be misused is not a reason to avoid developing said technology.

For example: It's possible to build an entire site surrounded by an iframe, so that navigation is completely broken. That doesn't mean that iframes have no legitimate uses.

It's also possible to build an entire site as a single AJAX app. This can be done well, but it takes more work -- for example, with Gmail, notice that everywhere you go, it adjusts the hash in the URL, so that you can use browser navigation properly -- the back button works, so does bookmarking, open in a new window/tab, etc etc. Sites that don't do that could have really poor usability.

It's also theoretically possible to render images using massive HTML tables, with each cell representing a single pixel. Does that mean HTML tables should be made less flexible, just so no one can do that?

I could go on...

The fact is, there are ways to abuse any technology -- there's always the possibility that someone will print out a website, make the changes they want, scan it back in, and upload it as an image. The fact that people can abuse technology should never prevent us from creating new, interesting bits of technology that have real, practical applications.

While some things obviously need Flash (such as Homestar Runner because they are Flash cartoons)

Nope. They need Flash because they were authored in Flash. They could have been done with SVG, Javascript, and the audio tag, it's just that the authoring tools for these aren't anywhere near Flash itself, from what I understand.

adding a high-end graphics card to a computer just to view the web? Thats just a bit ridiculous.

See, now you're being ridiculous.

Consider that ten or fifteen years ago, using excessively large images would be considered bad taste -- you'd be asking for way too much RAM "just to browse the web", and you'd be wasting a ton of bandwidth. That's why we came up with the idea of thumbnail galleries -- which are still useful, but a better model is really a slideshow.

It's not a "high end video card" now, either. Just about any video card is going to have some 3D capability on it -- and we're moving in the direction of compositing window managers, which will actually lead to cards supporting just 3D (and having to emulate 2D) being cheaper than cards supporting just 2D (and having to emulate 3D).

So, 10 or 15 years from now, when people want to add a little effect to their website -- or build an interesting "flash game" that's capable of actually using 3D hardware -- would you prefer it use Flash? Or maybe you'd prefer Quake Live -- a plugin for each game -- may as well just download an exe?

Or would

For one, this will add even more vulnerabilities to browsers which seem to already have loads of them.

While replacing one of the biggest ones: Flash.

WebGL won't be a plugin, it will b part of the browser. That means Firefox won't be vulnerable because of an Adobe bug, but because of a Mozilla bug, and Mozilla can fix the bug themselves.

Also, with more diversity, bugs will be less likely to be exploited, and when they are they will have a smaller path of destruction.

And for another the web should be accessible for -everyone- from the low-end netbook to a Core i7, and even older systems should be able to browse web.

This is no different than Flash is now, except that WebGL has the potential to be significantly more efficient. WebGL isn't going to replace HTML, it's going to augment it, similar to how Flash does today. Sites that want to be accessible to more users will avoid reliance on resource demanding WebGL elements, or avoid it altogether, just like sites avoid resource demanding Flash objects.

On the other hand, those sites that want to take advantage of it, and for those users with more modern machines (really, WebGL isn't going to require advanced GPUs and high-end Core2Duos unless you start putting game level 3D and AI into it, simple 3D rendering will work just fine on older hardware--better, in fact, that 3D Flash does now), we'll be able to have a more rich web experience.

I absolutely detest the notion that the web should not embrace new technologies just because some people have crap computers. I agree that most web sites should be designed to be accessible across a broad range of computers (either by limiting advanced features, or providing alternate pages), but if a site wants to specialize with features that tax even modern systems (like YouTube did not too long ago), then as long as they are not essential sites (like banks, utilities, government, news media, etc), then they should be encouraged.

Already many sites are unusable without a recent version of Flash, we don't need extra hardware as requirements to view sites.

There you go. So how is this worse?

how many of us have encountered sites built entirely in Flash? Or have a requirement of Flash for simple things like navigation? While some things obviously need Flash (such as Homestar Runner because they are Flash cartoons) others use Flash for no real reason.

Which has what to do with WebGL?

But adding a high-end graphics card to a computer just to view the web? Thats just a bit ridiculous.

Not as ridiculous as assuming WebGL will mean that you have to have a high-end GPU and CPU just to view the web.

The point is that nobody really cares all that much about what you do, as the web industry does not revolve around you.
