The question I have is whether we should go to PerspectiveModel 11 as the default for Jmol 11.2.
For zoom 100, there is only a slight difference. Try different zoom settings. You will see some differences, because Model 10 is a nonlinear model, while Model 11 is linear.
The effect is much more significant for larger models, where Model 11 corrects for major defects in Model 10 in relation to balls, sticks, and slabbing. For the , try it with and without slabbing. This problem is fixed in the . Notice the odd way the CH4 bonds intersect the carbon sphere with perspectiveModel=10. This is fixed in perspectiveModel=11. Notice that the zoom setting for Model 10 has to be at 32000, while the zoom for Model 11 is only 3200. This is because Model 10 is nonlinear.
