BIM data is quite big and complex!

 Hard to see and access BIM data without specific software!

Technologies are closed and proprietary!

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!

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.

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 just Java Script.

 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
