Papervision 2.0 Collada Import DAE from Sketchup

April 18th, 2008 · 18 Comments · Code

Papervision Collada Import

I’ve been working how to get models from Google Sketchup to Papervision. They currently are working on Collada parsers specific to Sketchup. That should make textures a tad bit easier. Until then;

Here is a link to the source code and a working example.

    Where did you get your Collada parser specific to Sketchup? Did you make it yourself?

    This example uses the DAE parser. Some people were working on parsers for the Sketchup format.

    How to get a usable DAE file out of Google Sketchup for PaperVision3d.

    1. Build your model in Google Sketchup (free version is fine)
    2. When your model is ready to go; File > Export, export as Google Earth KMZ file.
    3. Change “.kmz” extension of exported file to “.zip”
    4. Unzip package and find DAE file

    I’m not sure what the status is with the SketchUp parser, you might snoop through the latest build to see if anything got committed.

    Hello,
    Nice example.
    i have imported my own .dae file into your example.a more complex one with multole objects.
    i was trying to acsess an idividual objec within the new DAE () Object but with no sucsess…

    i tryed :

    var store:DisplayObject3D = holder.getChildByName(“Loja1″);

    do you how this is done ?

    thx.

    no matter what i try the sketchup exports a .kmz and if i zip/unzip this it remains a .kmz and does not access any .dae info–are you using the “pro” version? my kmz files keep showing up in my FLA as wireframes/no materials/bitmaps export…any help?
    tHanks! ge5

    @ge5

    I was not using the pro version. You don’t have to necessarily “zip” or archive the file, Google creates the package. Uou should be able to just change the file name extension to “zip”. Then unzip it.

    The support for materials and bitmaps were non-existent when I wrote this. I think the best bet for that might be the Blender importer, but Sketchup has a much easier learning curve than Blender.

    Also, Sketchup has come out w/ a new version, which I haven’t tested with this method.

    @Kiyoshii

    var store:DisplayObject3D = holder.getChildByName(”Loja1″);

    In your example here, what kind of object is “Loja1″? It looks like getChildByName() is a supported method. Is Loja1 also a DisplayObject3d when it’s created?

    @ge5

    (and all the other Sketchup version 6.+ users):

    You have to export as “Sketchup 5 kmz” format to have the DAE in the ZIP. I do not know why they did not implement the DAE in version 6+ kmz file format.

    Just starting my Papervision experience and stumbled upon this helpful blog. Thank you jacobmake!

    dude, you really should try making some models with Blender!!!!

    there is a collada export built right into Blender so you can poop the .dae files right out and plop them into your papervision engine

    I’m still learning the finer points of how this al works…. BUT!!! I did figure out this blender business is pretty simple as far as generation of Collada is concerned….

    ALSO

    Collada can not only transfer model data but it also can transfer a lot of other important data for material and physics and kinematic structure…. the trick is to make sure you have crossed all quad planes into triangles on your model so papervision doesn’t have a nervous break down…. (papervision is afraid of 4th corners on faces…. which makes sense because there is no subsurf generation in the engine, runtime of AS3 as of now couldn’t handle that… errrr or I’m sounding like an idiot now.)

    BARE IN MIND I only kinda know what I’m talking about….

    but yeah I’ll send you my links of materials and stuff….

    when you get blender google this kid super3boy

    this little 13 year old made some youtube tutorials that you can use to get enough modeling skills to make really nice models in Blender in a couple hours… it helps to have 2 computers or 2 monitors so you can have the video playing while you work in blender so you can follow along better….

    ALSO reading up on the Collada and what is is and where it came from is interesting and also informative at your range of use of this amazing tool…

    did you know it was invented for developing for the PS3 by sony? and afterwards was acquired by a open source company or something….

    Collada is also an evolving open source project.

    sketchup is a nice little toy but Blender is actually a powerful tool which is really wonderful to use, free, open source and is really about on par with maya in terms of power, modeling and rendering ability….

    but everything you need is there.

    @Alex – Thanks for the comments. I’ve tinkered around w/ Blender. Your right, it’s much more powerful than Sketchup, but I think some folks get scared off by the interface. I come from a 3-d background (Lightwave) and I found Blender to be a little more difficult to pickup vs. Sketchup, but probably worth the effort if someone wanted to invest the time.

    I did not know the history of the Collada file, thanks for sharing. It seems to be evolving and more and more 3d apps are allowing Collada exports which should soon make it easy to get PV3d models & textures from the apps of your choice.

    Hi, firstly id like to say this is really cool!
    I have a problem though, I downloaded your copy you have provided but when I compile it I get a few errors;

    Pultizer3d.as Line 39 – 1067: Implicit coercion of a value of type org.papervision3d.objects:DisplayObject3D to an unrelated type Number.

    Pultizer3d.as Line 58 – 1136: Incorrect number of arguments. Expected 0.

    Pultizer3d.as Line 64 – 1137: Incorrect number of arguments. Expected no more than 3.

    viewportLayer.as Line 76 – Warning: 3590: void used where a Boolean value was expected. The expression will be type coerced to Boolean.

    sophere.as Line 122 – Warning: 3590: void used where a Boolean value was expected. The expression will be type coerced to Boolean.

    Why am I getting these errors? I would like to develop this further but I’m stuck at the first hurdle :(

    please help me out…

    Dude, this works like magic :).
    Thanks heaps!!!

    This was really helpful i already knew that sketchup exported collada and i followed tutorials very sharply. But there is one more thing. Altho i can import my models and i see then and I can interact with them. Som parts are left as invisible. Now I’m thinking it might have something to do with the way i export the files out of sketchup, i just use the built in exporter and check all the options available. I’ll have a go at try and fail see what i get but if there was someone out there who knew the workaround this. I’d be very appreciated.

  • 15 Pedro // Apr 2, 2011 at 12:18 pm

    okay guys i found out my mistake… well its not really a mistake it more like a factor. Papervision is low poly, throw alot of polys at him and he will just garble everything up and show you emptiness. So Keep the poly really down.

    Искал в интернете угловой диван недорого,набрёл на сайт http://WWW.KIRA-MEBEL.RU понравился диван уютера ,на фото он такой красивый и цена вроде не кусается.Заказал его.Понравилось общение с менеджерами милые люди.
    Назначили доставку через 7 дней.
    Это были плюсы ….
    А теперь о минусах!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    Сроки сорвали. Привезли диван ночью.А так как я работаю таксистом меня не было дома, жена приняла его и расписалась заплатила денег. А диван я собирался сам собрать.
    На утро меня ждал сюрприз!!!Диван не соответствует картинке.Одним словом-на букву **Г**..Напутали с тканью.Одна часть одного цвета другая часть другого.
    Начал звонить -обьяснил проблему!сказали перезвонят.
    НЕПЕРЕЗВОНИЛИ!!!
    На следующий день опять звоню!Мне в ответ:жена ваша расписалась в получении о том что претензий не имеет!Да?
    Смотреть-надо.Закон прав потребителя читали?НЕТ!?
    Одним словом бла-бла-бла.Идите-нахюйй(конечно не прямым текстом)но послали.А ласковые менеджеры-стали собаками спустивших с цепи.
    Одним словом!
    Находят лохов.Впаривают некондицию.А в работу менеджеров входит динамить и отфутболивать!В работу-доставщиков привести ночью когда все спят и спарить!
    Вот бадаюсь-с этими козлами!!!

    Hi reading through your comments was very interesting i have made a model in skecthup however when i export as a dae and use this within papervision my model contains no textures. I have tried saving the model as a kmz changing to a zip and extracting the model this way however this doesnt work either.

    I noticed these comments where from along time ago has anybody come up with a way around this problem?

    URGENT HELP NEEDED

    thanks t2byt
