I thought it's time for a new Quick3D-HowTo-Video. It's been some time since the last one was posted. This time the video is more technical and less religious ;) I've nothing against Monkeyism, but let's be honest, devoted penguins are one thing, though the real stuff is cars, cars, cars!
I stumbled across a few bugs and missing features, namely QTBUG-20729, QTBUG-20731, QTBUG-20460. However, all of them could be easily worked around by slicing the 3D model into smaller portions. The video shows exactly how to do this right!
Another issue: models aren't always rendered as they should be. For example colors are totally wrong, textures missing or parts of the car aren't where they should be. Admittedly, this is more about the world being a flawed place but anything else. This could be observed in Blender as well as in Qt Quick 3D - and is always a problem when formats aren't fully standardized.
Yet after finding and slicing a suitable model, the rest was definitely a smooth ride - and great fun to develop!
Great tutorial! Amazing, how easy it is to make 3d applications with Qt Quick.

As I said last time
Qt 4.8 beta distribution for 32bit Linux
don't have libQtOpenGL :(
funny is
in windows distribution libQtOpenGL is :)
Why trolls why?

In Qt Quick 3D, Is it possible to implement own shaders, i.e. a glass shader that reminds more the real glass, refraction/reflection shaders? That would require multi-pass rendering too.
@aamir maniar: You mean learning Quick3D or learning 3D very fast?
For Quick3D:
There is no book. It's the documentation and blog entries.
For learning 3D very fast:
"3D" is a huge area. You need to be more specific :)
I for myself only got into OpenGL deeper, and I read: "The OpenGL SuperBible"

@m][sko: Thanks for making us aware of this issue with Qt. I have asked Eckhart Koppen who is our head of build/release about this issue. When I hear more information I will make a note here. For now this is not an issue with Qt Quick 3D.
That tells me that the issue is actually related to the SDK update feature not apparently installing OpenGL packages.
Just for future reference, its good to log detailed bug reports with enough information that we can reproduce the issue you're seeing. You can use the feedback feature built into the SDK Help > Report Bug.

Hi - Update from release guys:
"This seems to be a valid issue. There is some libs missing from our build machine, which caused this. Now the question is, should we (or SDK team) update the beta package still, or can we just wait for the 4.8 RC and make sure that it will be there (SDK team will do an update for the online installer with 4.8 RC). I would propose for the latter alternative."
This seems to answer the question of "Why?" - its simply an error with some library binaries missing.
At present I don't have a date for when the RC will be out. Note that the original post does include downloadable packages as listed under the section "Update".

@Joe, http://dl.dropbox.com/u/305... here you go dude :)
Thank you guys.. I got it. And I will share it to my Chinese friends with youku.com.
@m][sko: you can build Qt 4.8 on linux with opengl. Either build from sources or get packages for your distribution.
@Frederik Gladhorn: why trolls can't make it right or at least update current version on distribution servers?
Good Post!
Which book will you suggest for learning 3D quick? I am not able to find any?
Best Regards
http://www.technobits.net - Always remain technically updated.
