A TECHNIQUE FOR IDENTIFYING ATOMS FROM A SCREEN IMAGE

Improving the interfaces in molecular graphics applications, making th em more natural and easy to use, is an important task, given the curre nt complexity of the displayed objects and of modeling operations. Cli cking near an atom center is the usual method of atom selection. Howev er, this method has certain disadvantages when working with images com posed of different atomic representations such as sticks, CPK, or dott ed surfaces. We propose another technique allowing the user to obtain the correct answer when he or she clicks on any element of the atom im age.
