  12. 12. And then, What’s been newly developed?
  13. 13. 2 main cores of mago3D… F4D Format as a service formatC01. Mago3d.js as a improved rendererC02.
  14. 14. F4D: Why We Devised New Format? Increase rendering speed Optimize web service Make service data lightweight
  15. 15. 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.
  16. 16. F4D: Service Format Optimized for Web Service VS
  17. 17. F4D: Model-Reference Concept  Model is 3D geometry info, while Reference is real instance of this model
  18. 18. F4D: Model-Reference Concept With 4 geometric meshes - 4 models 23 objects are created. - 23 instances Image source :
  19. 19. F4D: Lego Style Service for LOD Detailed Resolution Coarse Resolution
  20. 20. 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
  21. 21. F4D: Visibility Index
  22. 22. mago3D.js: Let’s Piggyback!! Cesium mago3D World Wind 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
  23. 23. 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 Cesium/NASA World Wind WebGL Globe Core Mago3D Connector Mago3D.JS Mago3D Renderer Shader Mago3D Accelerator Performance Enhancer Mago3D REST API request, response Mago3D Process Manager Mago3D Data Container
  24. 24. 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.

  31. 31. 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
  32. 32. Success Story: Samsung Heavy Industries  Expected Benefits: • Increased productivity • Short response time to issues • Reduced fail cost • Easy collaboration between different teams
  33. 33. 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
  34. 34. Seeing is Believing – Samsung Heavy Industries
  35. 35. 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!
  36. 36. 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
  37. 37. 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
