Scanning Data

The amount of scanned data increasesThe time for scanning per scan position decreasesHuge models become more commonInteraction with models difficult

Due to amount of dataDue to complexity of geometry

Different Usertypes

Expert userInteracts often with the dataKnows the point modelKnows the program controls

Interested laymanVisitor to an exhibitionInteracts once with the dataDoes not know the dataDoes not know the program controls
