Introduction Perception and understanding of three dimensional crystal structures is a source of difficulty for many introductory students of mineralogy.
Traditionally, physical models of crystal structures (e.g., "ball and stick" and polyhedral models) have been used to help students better visualize the complex arrangements of atoms within crystalline materials. With the advent of newer computational and graphics technology, computerized virtual modelling of crystal structures and access to large crystal structure databases are now available to supplement traditional tools and methods of crystallographic instruction.
We believe that the full potential of crystal structure databases and visualization software for enhancing the teaching of crystallography has not been fully explored. In most mineralogy classes, such tools are used to illustrate concepts in crystallography and crystal-chemistry, but these sessions are mostly controlled by the instructor.
