[Chimera-users] level of detail (vrml)

Many thanks Greg for this reply!
The "problem" I face is the following:
Chimera enabled me to create an isosurface of a ribosome. Then a script
in Matlab enabled me to compose a scene made of 290 ribosomes (in order
to represent the crowding of the cytoplasm in E. coli) and to export in
the vrml format: one ribosome is the geometry, all the others are
When I open this 3D scene in Chimera, all is displayed quite
instantaneously but the navigation within the scene is slow. So, LoD
would have been a solution.
Do you think to something to make navigation faster? I could convert for
example the scene in the Chimera format in order to benefit from the LoD
capabilities of the software? In that case, I would need a part of
chimera format/script to do the conversion (for instance, a script that
instantiate a multiscale model in a given number of copies, at the right
place and orientation).
My best regards
