Mago3D is a web-based platform for visualizing and managing massive and complex 3D objects, integrating BIM (Building Information Modeling) and GIS (Geographic Information Systems) without requiring additional software installation. It utilizes open-source technologies to enhance 3D visualization, supports various industry standard formats, and aims to improve productivity and collaboration in construction processes, as demonstrated in a project by Samsung Heavy Industries. The project is funded by the Ministry of Land, Infrastructure and Transportation in Korea.

- 7. Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility.
- 9. BIM data is quite big and complex! Hard to see and access BIM data without specific software!
- 10. Technologies are closed and proprietary! Source: http://artist-3d.com/free_3d_models/graphics- file-formats.php 3D formats are usually created with professional CAD software Many 3D formats are proprietary with low inter-operability Hard to access proprietary technologies and formats!

It carries out data size reducing and pre-processing for fast rendering. JavaScript that expands existing WebGL Globe’s features to support BIM and indoor space.
- 20. F4D: Objectives Objectives of F4D are: 1- Reduce size of data for network traffic. 2- Create LOD (Level Of Detail) on service data. 3- Make visibility index for occlusion culling. 4- Divide and group data into spatial octree.

- 43. Success Story: Samsung Heavy Industries ? ? Issues around ship building process… • Usually waste the time to search a ship block. • Easily fail to find out the issued parts when use the drawings only. • Also feel difficult to communicate with each other using a cellphone or SNS. ※ 20 mins/block (mean time) Ship yard is too big & wide
- 44. Success Story: Samsung Heavy Industries Expected Benefits: • Increased productivity • Short response time to issues • Reduced fail cost • Easy collaboration between different teams
