[ASK]step-by-step building simple AR application

Hi everyone, I have some question to ask about building simple AR app with my own 3D model... #1 Can I integrate 3D model with (*.FBX) extension with eclipse like Unity do? #2 What files need to imported when I start building simple AR app? Actually I'm new with Android, Vuforia and openGL, so sorry for the dumb questions... Thanks... :)

Hi,

if you want to import 3D models in .FBX, you will need to integarate some 3rd parties libraries that support that feature,

Hi AlessandroB :)

Thx for you reply...

OK I think I got the point for question #2. Thx :)

Is there any best way that I can do to make my own 3D model works with my app?

[ASK]step-by-step building simple AR application

One way of making your model work with your app (if you don't use Unity) is to convert the model to OBJ format, and then convert the OBJ model to a header file using some script;

the whole procedure is detailed in this article:

OK.

I get all the points so far.

Now I'm wondering how do we add different model for every target we have in dataset?

Target 1 : Stones -> Model : Teapot

Target 2 : Chips -> Model : Sphere

Thx.

Hi AlessandroB,

Can I add Infinite Loop code in ImageTarget.cpp?

just like this

[ASK]step-by-step building simple AR application

Hi,

an infinite loop will make your application block in that rendering code, as you never exit the loop...

So, is there a way to make my model rotate dynamically?

I have one more question,

I have apply my own texture on my own model, but it's looks alike didn't fit with my model...

How do I fix it? here

[ASK]step-by-step building simple AR application

anyone can help my problem?

till now I'm stuck in here...

thx :)

glDisable(GL_CULL_FACE);

and then add this line right AFTER the glDrawArrays():

[ASK]step-by-step building simple AR application

it worked, thx :)

another problem, when I run my app in my device it can display the 3D model...

but not long after displayed the model it went crashed...

You're welcome.

Concerning your second question, about increasing the heap memory size of your app, this is Android-specific, and you can find many threads over the internet, for instance this is one:
