VESTA is originated from two applications, VICS and VEND, developed by R. A. Dilanian and F. Izumi during 2001-2004. VICS was for visualization of crystal structures, and VEND was for visualization of volumetric data. These programs were written in C language, and had many limitations because of their design concept. In 2004, K. Momma started to develop a succeeding application in C++, employing modern user interface framework wxWidgets. In June 2005, VICS-II was released as a successor to VICS, and features of VEND were further integrated into VICS-II to form a new, integrated visualization system VESTA.
