UnitCellVisualizer

This is an open-source lattice structure and unit cell simulation. It is designed for use in CHEM 124/127 at California Polytechnic State University, San Luis Obispo. The simulation has multiple features to facilitate learning of concepts in a lattice structures unit in a general chemistry course, such as generating lattices for the 3 basic cubic types and a few ionic compounds, a visual representation of how the unit cell makes the whole lattice, and coordination number views. The simulation is designed to be easy to use and interesting to look at. The simulation is written in JavaScript and uses WebGL to handle graphics. The simulation is currently available at http://atom.calpoly.edu/crystal .

Design Credit

• Dr. Zahra Alghoul: Initial specifications and chemistry knowledge.
• Dr. Zoe Wood: Graphics knowledge. Oversaw development on the simulation as part of Corbin's senior project, as well as Alec's final project for Intro to Graphics.
• Corbin Gruber: Initial simulation design. Lattice layering animation and unit cell drawings for the 3 basic lattices. Inspection and translucency features. Keystroke controls.
• Alec James: Updated Simulation design. Added in coordination number views. Incorporated Sodium Chloride and Calcium Fluoride options. Updated UI to use buttons on the screen, and dropdowns. Refactoring of code to make it easier to add more lattices in the future.
