  9. 9. 9 Introduction – Core parts of mago3D F4D Converter mago3D.js mago3D.js 3D GIS Engines Cesium WebWorldWind API API service html F4D Converter converts 3D formats(IFC, 3DS, OBJ, DAE, JT) to 3D internet service format F4D. It carries out data size reducing and pre-processing for fast rendering A plug-in composed of pure javascript which enables 3D GIS engines to handle large-sized and highly detailed AEC data F4D Converter F4D .ifc .3ds .obj .dae
  10. 10. Key technique : F4D, lightweight service format  Model is 3D geometry info, while Reference is real instance of this model 10
  11. 11. with 4 geometric meshes - 4 models 23 objects are created. - 23 references Image source : www.vecteezy.com Key technique : F4D, lightweight service format Example of Model-Reference 11
  12. 12. Key technique : F4D, lightweight service format 12 1. Build a triangular mesh based on the grid structure from the original three-dimensional data.

  14. 14. Key technique : F4D, lightweight service format 13 2. Triangle reduction (edge collapse) Inner edge collapse frontier edge collapse

  16. 16. Key technique : F4D, lightweight service format 14
  17. 17. Key technique : F4D, lightweight service format These are made from original data by adjusting details. 15 LOD 0 (Original data) LOD 2 LOD 3 LOD 4 LOD 5
  18. 18. Key technique : Culling for performance enhancement Do not render things not necessarily to be shown. before rotating a camera around a target during rotating after rotating Do not render if not necessary. 16
  19. 19. Key technique : Culling for performance enhancement visibility index An index describing which inner objects can be seen from selected positions in AEC. This index is used in occlusion culling in run-time visualization of mago3D. 17
  20. 20. Key technique : Culling for performance enhancement spatial index An index describing which inner objects are in cubes, spatial sub-divisions of AEC. This index is used in frustum culling in run-time visualization of mago3D. 18
  21. 21. Key technique : Culling for performance enhancement 1. When a camera position and 2. the viewing direction of it are setup, 3. mago3D does frustum culling on spatial indices 4. and do occlusion culling on the result of the frustum culling. 5. Finally mago3d finds targets to be rendered. (intersection between two indices) → It possible to select targets to be rendered without any complicated geometric operation in run-time. How to use both indices 19
  22. 22. 20 mago3D runs on any device Accessible anytime, anywhere
  23. 23. BIM(Indoor/Outdoor) integration Seamless integration of indoor and outdoor space on the same platform scene from indoor to outdoor through windows Scene from outdoor to indoor through windows 21
  24. 24. MEP Integration 22 Integration of large size MEP and 3D GIS on a web browser
  25. 25. AEC Integration 23 Integration of large size AEC and 3D GIS on a web browser
  26. 26. Various API supported (OpenAPIs) APIs are supported for developing application systems(currently 29 APIs) moving/rotating a full building moving objects & viewing attributes registration/monitoring/search of issues 24
