Using models from sketchup, rhino3d, etc posted by Tim Burt @ Wed, 07 May 2008 08:51:38 -0000

Hi all. I’m not sure if this is the right forum for this question – if not I apologise!

I’ve been experimenting with ARTag over the past few days, and am really excited by the possibilities it seems to open up. I study landscape architecture and can already think of billions of applications!! I’m having trouble using my own models, however. I’ve been trying with a range of different models I’ve created in both sketchup and rhino (including a terrain model with satellite image overlaid, a playground modelled in rhino with several different textures on it, and a few others) and get similar problems with both. Specifically, the models will either:
- appear fragmented, as though they’ve exploded
- appear correctly, but the materials won’t appear correctly (again, they appear fragmented)

I’ve tried using wrl, ase and obj formats, with the materials/jpgs in the directory, but can’t get it to work. Can anyone assist me with this?

ALSO, I’m keen to buy the book, and was wondering if it would be useful in helping me develop AR applications for things like interactive sunlight simulations. I’ve seen videos of people doing this, but I’d have NO idea how to develop such a thing!!

Thanks a lot!!

Hello, I’m Mark Fiala, the creator of ARTag. If you purchased the book you can download the Rev2K SDK for Windows, Linux, or MacOSX for free (for non-commercial private use that is) at the following link: http://www.artag.net/sdk_download/artag_sdk_download.php . Our regrets for the delay, there was a transition period between when the NRC offered it and it being released to me to distribute.

Enjoy!
Mark

The SDK link above seems to be for windows only and the link in the book to the SDKs is dead citing that it is temporary unavailable. The lib directory in the above SDK only contains C# and windows lib files only, no shared object files. I looked at some blog postings for last year and there were references to specific OSX and Linux ARTag SDKs link . The demos run fine on Windows link but my OpenGL skills are on Mac OS X.

Great book even if I am stuck with windows.

Self admitting Mac fan boy.

there is Linux and OSX code in the SDK and I believe there is also some in the book specific download (called “code”) which is available from the main book page on this site: http://www.pragprog.com/titles/cfar

Ok to fix the demo in OS X you need to copy the text_texture.ppm file to the Resources directory in XCode by right click – add – Existing Files. Then change main.c on line 23.

My main issue is that I need the ARTag code for OS X as well. I would prefer OS X as I have been developing OpenGL apps on the platform as well as Touchlib Multitouch apps using OpenCV and a tweaked Point Gray camera driver.

Any chance of the OS X source? Linux would be OK I can compile it on my PS3, I have OpenCV and the RSX workaround running on it.

Thanks

Mark

I’d like to see this for OS X too, it’s why I bought the book. The opengl_simple demo crashes on my MacBook Pro. Console says “no permissions” on the binary in the .app package. After fixing that, it couldn’t find text_texture.ppm. Anyone else have the same problem?

Thank you for the reply!

Is there a place to get the Linux version, too? I’m a Linux only kind of guy :)

It is a glitch, and we’re working on getting it resolved. Sorry about the hassle.

Until we get this sorted out, please use: http://www.halobattleguide.com/drop/artag_rev2k_sdk_windows_1209.zip

Note that you don’t need the SDK to run the compiled examples that come with the book download (available from this site), you only need the SDK to compile ARTag programs.

The ARTag SDK seems to be missing, at least at the moment. The site artag.net links to a page that exists, but lacks any SDK download links.

Maybe this is just a temporary glitch? Anybody has any alternative site for the SDK?
