Hi
I have managed to change the teapot 3d object to a 3D object of my choice but I was wondering if there is a way to change the 3D object displayed dynamically the same way we can change the dataset at runtime.
For example when my application recognizes the "stones" trackable it renders the teapot but with a press of a button in the menu the teapot changes into a banana 3D object.
Thanks

You should be able to do this by reassigning the arrays and indices counts used for rendering these models. Are you familiar with how to load models using header files?

Thanks for the reply but I figured out the solution . That was what I actually did .

How should I reassign the arrays and indices counts used for rendering models. I am able to generate .h files from .obj using the perl script. When the .h file gets generated it is 80% full of numbers.
Where should I make changes to replace existing Q, C, A, R with my current model

You're working from the FrameMarker's sample?

Thank you for your reply.
I tried to follow your instructions and was successfully able to generate .so file.
But, When I try to run the code on device the program exists when camera previews the marker with the following logs

Can you post the modifications that you'd made to your C++ file? - I don't need the whole file, just the revised sections.
Also have you been able to run the Vuforia samples on the device that you're using?

Yes, I have been using the vuforia samples on the device that I am using.
I also did check and my texture is loading in my application. It is only when the marker 1 is focused the application crashes with error

Also be sure to use
glDrawArrays(GL_TRIANGLES, 0, numVertices) rather than glDrawElements being that your model doesn't have indices.

Could you please post your method? You would help me alot since I'm having the same problem.
Would be very nice^^

There are instructions for rendering your own model in this thread - https://ar.qualcomm.at/content/replace-3d-model-different-3d-model

David is right. Instructions on following two places helped me to solve the problem.

Thanks for your reply
but these threads are not really what I need right now ^^;
I already worked through them a week ago and I already have my own trackables and my own 3d modell (all working fine)
