A query regarding 3ds Max

June 23, 2011 - 3:35am #1

Hi,

I am a student and I am checking the feasibility of using QCAR for my final project.

I could run the ImageTargets sample under 'SDK' section but when I tried to run the sample as described under ‘Unity Extension’ section, I am seeing a message as "Your license does not cover Android Publishing". Hence I went through the forum threads and then mailed Unit support for requesting the trial.

While I am waiting for their reply, I am wondering whether I really need the Unity extension. The application I want to develop includes 3D models. I could not understand from the QCAR architecture diagram, how exactly 3D models are incorporated with the application. This might sound like a childish question but is there any means to use 3ds Max for this purpose? Something like exporting the models as .FBX files and then programming with QCAR?

Thanks,
Kranti

That's right, you do not need Android Pro or Unity Pro, just the regular Android add-on.

Thanks for your reply.

I definitely will have to work on animation and as you mentioned, Unity seems the best option.

I apologize for my confusion but am I correct in interpreting that Android-Pro is not required (which requires Unity-Pro)?
Right now I have installed the free version of Unity. In other words, is it sufficient to have the 'Android' add-on which comes with one month trial?

Thanks,
Kranti

QCAR doesn't include any support for loading or rendering models. Rather, it sets you up to use OpenGL ES (1.x or 2.0) for this purpose. It's up to you to either write a model loader or find a 3rd party solution that you can integrate.

If your models are static and can be saved out as .obj files then loading them isn't all that difficult. There are lots of threads in this forum that explain how to do this, e.g. http://ar.qualcomm.at/node/2000231

If your models include animations then it's a good bit trickier. I would recommend finding a loader/render or game engine that's easy to integrate with an Android NDK project. Writing it yourself could also be a fun exercise, but it's a lot of work :)

Unity is great for easily importing and rendering animated models, but you do need the Android add on (standard is fine).
