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

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