Abstract: In the perspective of the cognitive process and the demand of diverse learning needs in the
future, this paper presents a mobile learning system of engineering graphics based on the android
platform and describes the main program of underlying structure, function and technology solutions.
The mobile learning system of engineering graphics is designed based on virtual reality (VR), which
is combined with JPCT-AE 3D engine, 3DsMAX and OpenGL ES 2.0 on the mobile terminals. In
particular, according to the cognitive rules of engineering graphics course, this kind of application is
characterized by split-screen function that displays multimedia and 3D virtual models at the same
time. It also achieves interactive control of virtual models.

Key words: virtual reality, engineering graphics, virtual model, split-screen function
