[Chimera-users] visualization code optimized using GPU shaders ?

Dear Chimera developers, I try to have a brief overview of molecular programs that can use programmable capabilities of new graphic hardwares (i.e. use of shaders): So, I would like to know if Chimera program have dedicated code that use such shaders to visualize fastly surfaces or to add particular lighting effects.. Thank you in advance. Matthieu Chavent.
