If i want to place QWebKit on top of OpenGL what is the best way to do it ?

[umen242]

does this example :
http://labs.qt.nokia.com/2008/06/27/accelerate-your-widgets-with-opengl/
from 2008 is valid or there is better ways now in 2011?

[zester]

Is this what you were referring to?

hi
yes , i download you model viewer modified demo
do you have any source code to this browser code??

[zester]

I don't understand.

Line 70 - 74 of openglscene.cpp

@
QWebView *webView = new QWebView();
webView->load(QUrl("http://developer.qt.nokia.com/forums/viewthread/6151/"));

QWidget *instructions = createDialog(tr("Web Browser"));
instructions->layout()->addWidget(webView);

@

Then just go to http://doc.qt.nokia.com/4.7/qtwebkit.html
or in particular http://doc.qt.nokia.com/4.7/qwebview.html

You will find all of the api's to make the web browser of your dreams ;)

[umen242]

i guess your code that i was download is not updated with browser example

[umen242]

my mistake i did't download your link..
wow performance is really crap ... hope that Qt will fix that in the next versions

[zester]

No problem... lol Probably why you don't see alot of 3D Qt Web Browsers out there.

[zester]

If your feeling adventures there is also Berkelium it's made to render to an OpenGL or DirectX texture.

Berkelium is a BSD licensed library that provides off-screen browser rendering via Google's open source Chromium web browser.

It takes advantage of Chromium's multiprocess rendering to isolate browsers from each other and can render to any buffer in memory. The user of the library can inject input and javascript code into web pages to control them, as well as listen for events generated by the page such as navigation events, load sequence events and paint events. Berkelium provides a small API for embedding a fully functional browser into any application.

wow this is great stuff!

Being that you posted this in the Game Development forum, might I make a suggestion for a game development framework.

For water there is Hydrax

For Sky and Weather Effects there is SkyX
http://www.ogre3d.org/tikiwiki/SkyX
Note: It,s used in the Hydrax screenshot above.

There actually really easy to use.

There is also.....

Note: Berkelium can be used directly with Ogre3D and Qt

Impressive work zester!

Great stuff , thanks!
Hi
are you doing planing to do the game in Qt3d?

[zester]

bq. Hi are you doing planing to do the game in Qt3d?

Qt3d was a consideration. After trying it out for sometime I came to the conclusion that for my
"No Rest For The Wicked" project it wasn't a very good fit. Qt3d AFAIK has issues with lights and doesn't
have bone animation support. Both of those issues are deal breakers.

As of right now for a Highpoly game OGRE3D is the best fit and for a Lowpoly Browser Based
game Three.js is the best fit.

Why? What did you have in mind?

[umen242]

I have in my mind to make interactive applications for kids , not 3d games in my opinion its very full market of indie game makers and wannabe game makers very hard to put something good .
its fun its great programming challenge but with no ROI for your work.
now im looking for platform , Qt is winner for me.

[zester]

Qt3d would be a good fit for interactive applications for kids.
