And then,
What’s been newly
developed?
2 main cores of mago3D…
F4D Format as a service formatC01.
Mago3d.js as a improved rendererC02.
F4D: Why We Devised New Format?
Increase
rendering
speed
Optimize

service
Make
service data
lightweight
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.
F4D: Service Format Optimized for Web Service
VS
F4D: Model-Reference Concept
 Model is 3D geometry info, while Reference is real instance of this model
F4D: Model-Reference Concept
With 4 geometric meshes - 4 models 23 objects are created. - 23 instances

F4D: Lego Style Service for LOD

Coarse Resolution
F4D: How to make LOD
Third, merge
collected cubes
as much as possible
Second, collect
cubes which
intersects with
original data
First, divide the
Bounding Box into
enough small cubes
for each LOD
F4D: Visibility Index
mago3D.js: Let’s Piggyback!!
Cesium

mago3D
WebGL
mago3D
1. A plug-in to any web 3D engines based on WebGL.
2. A set of JavaScript for web developments.
3. Not an WebGL Globe, But a plug-in.
ismago3D.js
mago3D.js: Components
1. maog3D.js has been designed
and developed as an independent
plug-in to the existing WebGL
Globe.
2. mago3D.js added new
functionalities and enhanced
performance of existing WebGL
Globle.

mago3D.js: Components
1. mago3D Connector that interacts with WebGL Globe such as
Cesium, World Wind.
2. mago3D Renderer that shades and renders 3D data.
3. mago3D Accelerator that enhance performance such as frustum &
occlusion culling, indexing, LOD(Level Of Detail) handing.
4. mago3D Data Container that contains and manages 3D data.
5. mago3D Process Manager that manages whole process from data
receiving to rendering.
6. mago3D REST API that provides API for 3D data sending and
receiving.

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
Success Story: Samsung Heavy Industries
 Expected Benefits:
• Increased productivity
• Short response time to issues
• Reduced fail cost
• Easy collaboration between different teams
Success Story: Samsung Heavy Industries
 Project Name: SHI Smart Yard System
 Goal: Monitoring the ship building process in 3D CPS(Cyber-Physical Space)
CAD Files
mago3D Parts
Seeing is Believing – Samsung Heavy Industries
Future Plan – Support New Data Types
meteorological/weather data
real-time data
(IOT, sensor/observation data)
point cloud
 mago3D will be capable of handling more types of data in near future!
Future Plan – Functionality Enhancements
Type Items
Analysis
Density map, Standard ellipse, Cost surface data, Whisker analysis, Detection
abnormality from IOT data, etc
Operation Raster operation(filtering, smoothing…), Coverage rebuild, etc
Styling Volume rendering, 3D vector/streamline, Cubing, etc
UI Different view controlling at indoor/outdoor space, etc
 mago3D will also leverage existing open source projects
Wrapping-up
• Open source – Apache and AGPL license
• Web based – no need to install additional program
• Supports industry standard formats(ifc, 3ds, dae, kml, gltf…)
• Massive 3D data rendering
• In-Browser 3D objects moving/rotation/heading adjustment
• Highly extensible architecture
• BIM/AEC and 3D GIS integration

  • 17. And then, What’s been newly developed?
  • 18. 2 main cores of mago3D… F4D Format as a service formatC01. Mago3d.js as a improved rendererC02.
  • 19. F4D: Why We Devised New Format? Increase rendering speed Optimize web service Make service data lightweight
  • 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.

  • 36. 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
  • 37. Success Story: Samsung Heavy Industries  Expected Benefits: • Increased productivity • Short response time to issues • Reduced fail cost • Easy collaboration between different teams
  • 38. Success Story: Samsung Heavy Industries  Project Name: SHI Smart Yard System  Goal: Monitoring the ship building process in 3D CPS(Cyber-Physical Space) CAD Files mago3D Parts
  • 39. Seeing is Believing – Samsung Heavy Industries
  • 40. Future Plan – Support New Data Types meteorological/weather data real-time data (IOT, sensor/observation data) point cloud  mago3D will be capable of handling more types of data in near future!
  • 41. Future Plan – Functionality Enhancements Type Items Analysis Density map, Standard ellipse, Cost surface data, Whisker analysis, Detection abnormality from IOT data, etc Operation Raster operation(filtering, smoothing…), Coverage rebuild, etc Styling Volume rendering, 3D vector/streamline, Cubing, etc UI Different view controlling at indoor/outdoor space, etc  mago3D will also leverage existing open source projects
  • 42. Wrapping-up • Open source – Apache and AGPL license • Web based – no need to install additional program • Supports industry standard formats(ifc, 3ds, dae, kml, gltf…) • Massive 3D data rendering • In-Browser 3D objects moving/rotation/heading adjustment • Highly extensible architecture • BIM/AEC and 3D GIS integration
