Shows how to display one entity with several render modes at once. The sidechains are displayed simple mode, whereas the backbone is displayed with smooth lines.
# remove all objects from scene, just in case scene.RemoveAll() # Load chain A of SDH ent = io.LoadPDB('data/sdh.pdb', restrict_chains='A') # create graphics object go = gfx.Entity('SDH', ent) # set rendermode of full graphical object to interpolated spline go.SetRenderMode(gfx.SLINE) # select sidechains (including bond to C-alpha and N in case of proline) sidechains = ent.Select('aname!=CA,C,N,O', mol.EXCLUSIVE_BONDS) # set rendering of sidechains to simple go.SetRenderMode(gfx.SIMPLE, sidechains) # add object to scene scene.Add(go) # center the scene on the geometric center of the SDH scene.CenterOn(go) print 'Demo 1: loading and displaying a pdb file'
