I'm trying to develop a Unity Application that requires setting the image to track at runtime using Web Service.
Is there a way to do this by making a WTC or something like it?
If you just want to track a single target, you can point the image tracker at a PNG or JPEG file, either on device or with a URL.
If you need to track more than one target, then you can create a ZIP file with multiple PNG or JPEG files included. This also needs to be saved either on the device, or accessible through a URL.
