Unfortunately, our 3d engine does not support all needed features. Most 
important problem is, that in our 3d engine only the first light is 
specular. We need three specular lights for MS Office light rigs. 
"Specular" means, that the light produces a bright spot on the shape.

Further problem with our 3d engine is, that we cannot render the "Bevel" 
of MS Office. Not only the fancy ones, but the simple round bevel is 
missing too. Our "Rounded edges" are in fact straight. In MS Office you 
can use the bevel to create a sphere, for example.

Nevertheless, extending ODF is likely needed anyway. That would include 
extending our API because the import goes via API properties. The 
question is more whether to start that immediately or first implement 
some ersatz lighting so that the shapes are approximately as light as in 
MS Office. When you use the current import (in daily build which has the 
3d geometry) you can see, that our default lighting gives bad results.

Kind regards,
Regina
