Question about number of trackables

November 7, 2010 - 8:08am #1

Hi,

I will probably use QCAR SDK in my final career work, but first I would like to ask a few questions:

1 - The guide specifies a maximum of 5 simultaneously frame markers and 5 simultaneously image targets. Can I combine image targets with frame markers, i.e. 2 image targets and 4 frame markers?

2 - The number of virtual buttons can be more than 5?

Thanks.

Those numbers are more of a guide than anything else, I believe the system will allow you to track more of each. At a certain point performance will decrease, however, if you are attempting to track too many targets at once. I suggest playing around with it and finding a balance that suits your needs, though remember that not all Android devices have the same capabilities.

You can track any number of frame markers and image targets simultaneously, with the above caveat concerning performance.

I also believe you can have more than five virtual buttons, but you will want to be thoughtful about how you place them, so that the user doesn't accidentally trigger them.
