Culture 3D Cloud
Image-based modeling web service :
• Dedicated to CH community
• Versatile (scale, objects/scenes)
• High-density and accurate output
• Open-source software
![Page 10: Geometric Modeling of 3D Environments - Culture](https://reader030.fdocuments.in/reader030/viewer/2022012500/6179d196f6b8107cad449ced/html5/thumbnails/10.jpg)
Objectives
Digitization:
• Large use of digital cameras
• Widespread expert knowledge in photography
-> image-based modeling
• Enabling non-expert end-users
1. Acquisition settings and protocols
2. Automatic remote computing
3. Storage and sharing
4. Online visualization
