And then,

What’s been newly developed?

2 main cores of mago3D…

F4D Format as a service format C01.

Mago3d.js as a improved rendererC02.

F4D: Why We Devised New Format?

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

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

Third, mergecollected cubesas much as possible

Second, collect cubes whichintersects withoriginal data

First, divide the Bounding Box intoenough small cubes for each LOD

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)

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

AnalysisDensity 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
