I'm not perfectly sure what you are asking, specifically. Would you like to run the model's animation when touching the screen?
It this what you were trying to achieve? Or did I misunderstand the question?
We have used wikitude sdk in phonegap application to track our AR targets. One of the file is showing animation on touch and we are using wt3 file for that.
As per the guideline - we have used animation group and poly-surfaces to animate on touch. But its not working on touch using different poly-surfaces.
We tried with sample wt3 and its poly-surfaces and it working. Can you please check attached wt3 and provide solution which poly-surfaces we need to use.
