Can I create visual planes to show where can user put 3D models?

Question

Greeting, 

New to EasyAR and hope that I can learn more from this forum.
Currently I using EasyAR Surface Tracker to insert 3D model, but my team suggest that it would be better to include visual plane for the user to know where they can put 3D model. For Example:-

Try this sample in the latest package: http://help.easyar.com/EasyAR%20Sense%20Unity%20Plugin/Samples/WorldSensing/MotionTracking.html

You can use the same method in above sample to draw plane when using surface tracking. The difference is, the motion tracking will try to fit a plane but surface tracking will not. But there will not be so much different when you are looking at a horizontal plane.

For the differences about motion tracking and surface tracking, please read

Choose a suitable one for your scenario.
