Several key technologies of virtual simulation on aviation ammunition teaching software

Abstract

In order to solve the inconsistent problem between updating quickly for the air ammunition and updating slowly for the teaching materials, and meet troops' training and teaching demands, the virtual simulation technology is introduced in the teaching software of aviation ammunition development. The virtual simulation technology includes IGES (Initial Graphics Exchange Specification) entity model construction technology, which implement the new NURBS model. Entity object optimization technology alleviates the complicated structure of air ammunition body for optimizing the virtual reality environment. Key frame animation technology can make the drawing performance related to computer hardware and scene based on high-precision time stamp. These technologies improve the interaction and intelligence of teaching software, and provide a kind of powerful supplementary means for the autonomous learning and classroom teaching of aviation ammunition. © 2012 Springer-Verlag.
