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

19. Key technique : Culling for performance enhancement
Do not render things not necessary to be shown.
before rotating a camera
around a target
during rotating after rotating
Do not render if not necessary.

20. 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

21. 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

22. 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
