Google Launches 3D Driver Project For Chrome 63
CWmike writes "Google has launched a new project for Chrome that will let the browser run a wider range of 3D graphics content without downloading additional drivers. The open-source project, called ANGLE (Almost Native Graphics Layer Engine), seeks to let Chromium run WebGL content on Windows computers, wrote product manager Henry Bridge on the Chromium blog. WebGL is still-developing a cross-platform Web standard for accessing low-level 3D graphics hardware based on the OpenGL ES 2.0 API (application programming interface) that can be implemented directly in a browser without a plugin. 'ANGLE will allow Windows users to run WebGL content without having to find and install new drivers for their system,' Bridge wrote. Because ANGLE aims to use most of the OpenGL ES 2.0 API, it may help developers working on mobile and embedded devices, Bridge wrote. 'ANGLE should make it simpler to prototype these applications on Windows and also gives developers new options for deploying production versions of their code to the desktop.'"

What is, and what isn't?
WebGL is an API based on OpenGL ES 2.0, which is also an API.
The OpenGL API is usually provided by a driver. ANGLE, on the other hand, implements the OpenGL ES 2.0 API on top of Direct3D, thus eliminating the need for a driver that supplies OpenGL.

It's rather odd to do this though, given that every current and past nVidia, ATi and Intel graphics driver that I'm aware of *does* support OpenGL. Though perhaps not ES 2.0 (they're not embedded). I'm surprised they don't just translate into desktop OpenGL calls.
Re:API (Score:4, Informative)
The problem is that the drivers typically installed by Windows (and that exist on many machines) dont include all the OpenGL bits that the proper vendor drivers contain, hence the need to download drivers from the ATI or NVIDIA or Intel site to get good OpenGL support.

If you install Windows Vista or 7 from CD, it will recognize your graphics card and install a driver for it that was current at the time. Assuming your graphics card isn't a completely new platform, you will get full color and resolution on first install (though maybe not with up-to-date drivers).

It has probably been quite a while then, since you checked.
For at least Windows 7 and Windows Vista you will get support for a full resolution (and I believe color depth) that your monitor supports. At least if you have an ATI or Nvidia card. Graphic performance will be poor, but you will be able to browse your web or work with your office apps.
If I remember properly Windows XP was quite OK in that department as well (at least installs with SP2 integrated).

the current version of Windows (7) automatically downloads updated WHQL drivers via WIndows update at install time, if your PC is connected to the net.
If you're not connected at the time of install, you'll get driver updates along with windows updates next time an update completes successfully.
WHQL drivers are not the most current, but they usually are good enough.

What a load of crap. Sorry man. The kernel world isn't really fragmented if your talking about hardware. All distros pull the kernel sources from the same place and just tweak it. As far as hardware support is concerned "fragmentation" is not a problem. There is not any valid reason for hardware manufacturers not to have kernel drivers. Fragmentation in linux is an annoying myth.

It's not so much that OpenGL ES is implemented on top of OpenGL, it's that you can just call OpenGL as usual instead of OpenGL ES, since most functions are just the exact same thing. OpenGL ES just leaves functionality out (assuming your OpenGL implementation is new enough).

Besides, pretty much any driver for any modern video card out there supports OpenGL, why would they want to do this?
Maybe because they actually tried to use OpenGL and found it wouldn't work quite as smoothly as you think it does? You know, they are actually writing a browser used by a huge number of people here, they actually have some experience with these things. They're not doing this for the hell of it.

Why would it double the download size? Did you RTFA? ANGLE is a translation layer that converts OpenGL calls into Direct3D calls. That is probably going to be "largeish" but it doesn't mean actually bundling drivers with Chrome itself.
The problem this solves - in many cases OpenGL drivers on Windows don't actually exist or are unusably bad. If I was feeling uncharitable, I'd say the web/html5 community seems to be doing another video tag fiasco, in trying to set another standard that ignores marketplace realities (cross platform opengl is dead). By releasing ANGLE Google is trying to make Web3D not entirely irrelevant. This is only one of the many hurdles [google.com] originally identified by the Chrome 3D graphics team.

The issue is that Microsoft usually ships Windows with subpar distributions of graphics drivers for 3D support in general(not just OpenGL) compared to actual vendor drivers in terms of feature support beyond what you need to use basic Windows programs. Probably in some attempt to provide marginally more stable drivers historically under the assumption most users wouldn't need anything more than basic API support and everyone else would have their apps somehow manage to install/warn them to get a better driver package. This doesn't really work for WebGL, however.
Google could just have their installer get you to update your GPU driver, but overall this is probably a cleaner solution for long term support since you have about +/- 10 year support expectations for Direct3D on a GPU in a way that is far better tested than OpenGL for "last years model".

So wether or not it's the card vendors or Microsoft, it's a fact that Microsoft created the non-uniformity of the 3D api world, by introducing its own non-open non-crossplatform standard.
So ofcourse one can run OpenGL on Windows, but it's not easy, not standard, and often works badly. Which is exactly what Microsoft wanted when it created DirectX. A new 3D standard, that would be used in gaming, and that would make it harder (i.e. more expensive) for applications to be crossplatform; it thereby served its purpose: continuing and extending the dominance of the Windows platform.
