Applied technologies for 3D creation
Technologies for creating 3D objects in thee-museum are:
3D Laser Scanning(using 3D laser scanner)
Photographic VR(using digital camera)
12
Equipments• 3D laser scanning
– 3D Laser scanner– 3D Modeling software– Lighting set– Turntable
• Photographic VR– Digital camera– VR software– Lighting set– Turntable
