1. Introduction
Thanks for your interest in OSLite. OSLite is a free,lightweight,developing program for OpenSees visualization. I am very happy to have the opportunity to distribute this software for OSLite users. I encourage everyone to try out all of the functions of the program and send me criticism, corrections or suggestions to improve future versions. I also encourage users to e-mail me at “jacques dot chen At qq dot com”.
