WebGL:Picking in GLGE

admin — Sun, 17 Jan 2010 19:26:52 +0000

Another week past and I’ve been busy adding picking to the list of GLGE’s features. This turned out to be more challanging then I had first thought, mainly due to hours trying to find a stupid mistake I made early on I’ve still got to do some optimization, but it’s reasonable performance at the moment. Hopefully, I’ll be able to use the object culling I’m planing for the scene to speed up the picking as well

This week I’ve taken a bit of a break on the coding. I’ve now got a website up and running for GLGE as well as officially releasing an alpha:

GLGE Website

I’ve also spent a few days coming up with a more impressive demo. Please bare in mind I’m no pro CG artist, just a now and then amateur, so imagine what could be achieved by the pros in a very short space of time. It’s not showing off 100% of the current feature set, some of which I think still needs rewriting and finishing off. But, hopefully it’ll be enough to change the mind of at least some of the WebGL naysayers, encourage more rapid development and make 2010 the year of 3D on the web.

Annoyingly it isn’t working on firefox (at least not my GFX card) there seems to be a bug where you can only map 4 textures to a shader Hopefully, they’ll get that fixed soon. In the mean time I’ve tested it on chrome and it runs at an okay frame rate, although I do think it’s time to get some optimization in there.

WebGL Spotlights and animation

Another update:

Targets acheived this week:

1) spotlights are now done and dusted

2) made the animation system more generic(the aim is to make everything easy to animate), see the scrolling material layer on the floor of this weeks demo and the movement of the spot lights

3) started writting an XML file format to make things a bit easier when it comes to handling resources

4) fog is on hold until untill I’ve got round to doing some turrain to demo it

See the Latest Demo Here

(Sorry still now video under linux again)

It’s been a very very busy week I’ve nearly doubled the size of the library. I looked into importing collada files and I don’t think

It’s all that practical, for more then basic mesh import. It’s an excellant generic format but it’s highly involved and since the whole

purpose of the library was to abstract away the complexity I’ve decided to try and map a very simple XML format directly to the library.

For example the material for animated floor in the demo is expressed as:

-5.47,0.0,1.0,0.0,8.34,0.0

12.28,1.0,30.22,1.0,36.84,1.0

31.16,0.0,40.0,0.0,46.32,0.0

Github does seem to be the best I’ve checkout so far. I’ve put up some preliminary documentation for anybody intrested Initially docs

The latest demo is up, sorry for the insane animated material but I just wanted to do something to demo the animation system.

I may still reconsider and start a collada import but it will be some time off.

I’m starting to think it’s nearly time to release(at least as an alpha, since the api is still changing on a daily basis). I’ve been looking into github(many thanks to Giles Thomas for pointing me that way). Any other suggestions out there? Github does seem to be the best I’ve checkout so far. I’ve also put up some preliminary documentation for anybody intrested.
