As we will dsicover, writing lenses definitions yourself isn’t difficult at all; however, it is usually tedious if there are lots of fields to create lenses for, and thus automatic generation is quite convenient. Symplectic ray tracing based on Hamiltonian optics in gradient-index media. Bifocal lenses include two lens powers – one for seeing objects…
