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 instantiations. 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 Damien Greg Couch a écrit :
Sorry, chimera does not support VRML's LOD node. Looking at the specification, it wouldn't be too hard to implement, just takes time. So the question becomes, how important is it to you? And would always displaying the first node be okay?
Salut,
Greg

Dear all,
Chimera is able to display VRML file.
Is it able to display VRML file containing level of detail? (My first tentative was not a success but I do not think the file I used respected the format convention).
My best reagrds
