Re: [osg-users] ANGLE - a possible helper under Windows?
Hi Robert, What is the release schedule for OSG 3.0? I would also love to showcase something based on OSG in Google IO which is on May 19th. Can you think of an existing OSG demo that can be ported to GLES 2.0? The motivation behind using Native Client instead of WebGL is that in addition to rendering you have other stuff like physics, terrain decoding, etc. -Alok On Fri, Mar 19, 2010 at 1:55 PM, Robert Osfield robert.osfi...@gmail.com wrote: Hi Alok, On Fri, Mar 19, 2010 at 6:20 PM, Alok Priyadarshi al...@chromium.org wrote: I am one of the contributors to the ANGLE project.

Do you have thoughts on how long it might take to do the port to native-client? I'm wondering if it'd be possible to roll support into OSG-3.0.

I don't have a specific schedule for OSG 3.0, I have set a couple of feature targets for 3.0 that haven't yet been tackled - the key one being shader composition.

The motivation behind using Native Client instead of WebGL is that in addition to rendering you have other stuff like physics, terrain decoding, etc. I don't have any sophisticated demos to hand, but I'm sure we could put together a few technology demos together if the community pitch in :-) Such demos don't require OSG-3.0 though, a dev release would be sufficient. I would say that I'd very much like to have 3.0 done by mid May, I don't yet know how practical this is though - it depends upon how complex shader composition turns out to be, and how much commercial work I take on.

Interesting. Maybe a way to have osg on XBox :)) -Nick On Fri, Mar 19, 2010 at 6:50 PM, Robert Osfield robert.osfi...@gmail.comwrote: Hi All, I just came across this article that talks about a google project called ANGLE that is developing a wrapper that maps GLES 2.0 calls to Direct3D 9.0. GLES 2.0 being a pretty small subset of full OpenGL makes the task rather more straight forward that wrapper GL 1.x/GL 2.x/GL 3.x, still not trivial but should be make it more likely to succeed. The article is: http://www.theregister.co.uk/2010/03/19/google_webgl_windows_fix/ It's an interesting development as it's well established that some hardware vendors don't support OpenGL well under Windows, so it might make a possible workaround for members of the OSG community. It does mean you'll need to have a GLES 2.0 target in your app to take advantage of this, but this isn't too difficult now that the OSG has GLES 2.0 support. Once we get more mature fixed function to shader pipeline setup this should become even more seamless. I'm no windows hack so I'll have to leave it to members of the OSG community to investigate further, but potentially we could adds support for linking against ANGLE if this project takes off.
