Note that the markers should be randomly distributed to avoid regular arrangement 

(Figure6- 2). 

 

Figure6- 2 The wrong way of pasting 

In addition, you should pay attention to avoid overlapping, hidden or damaged 

markers when pasting points. If the object needs to be sprayed powder(for example, 

scanning black, transparent or shining objects), first spray the powder and then paste 

the points.
