Modeling

Data exchange

After finishing the first evaluations, it became clear that reconstructing threedimensional virtual objects is out of question. This is because most of the incoming models only are 2D and therefore unsuitable for creating VR-models. It is still possible to use those 2D-models as drafts, but this requires a data conversion from the CAD-data to a Computer Graphics Metafile (CGM).

Modeling

The first object to be modeled from the 2D-draft was the "PASS"-tank that seems to be very complicated due to its surfaces of free shape. The geometry was taken from the CAD-drawing while the textures and colors came from the pictures taken in the showroom of ABB in Oerlikon. The result is very detailed virtual mockup for the "PASS"-type as shown in the following pictures:

As this model will be used for a later animation, small objects like screws are not visualized as a texture but are also modeled as objects. Some details were corrected afterwards, e.g. a sensor underneath the isolators:

In a next step, the "GIS"-type was modeled. The geometry of this switch is not as complicated as the "PASS" and can mostly be reduced to simple objects like cylinders or cubes:

The  "LTP"-switch is modeled too:

Special textures, e.g. the factory brandmark, increase the immersion of the visualized objects:

To improve the immersion, the above modeled objects are integrated in a first layout of a power station. This very first setup shows a fictive scenario but still gives a first impression how the switches are integrated into a power station.

An improved model has optimized textures and more realistic shadows:
