Facio is an OpenGL-based 3D-graphics program for molecular modeling and visualization of quantum chemical calculations (GAMESS and Gaussian)
Since Facio internally uses PDB (Protein Data Bank) format, it can also display a 3D-structure of biological macromolecules, such as proteins and nucleic acid with emphasizing their secondary or quaternary structures.
