Abstract
This paper devotes to developing an interactive visualization system of 3D lunar model with texture and labels on mobile device. Using OpenGL ES 2.0 and Osg for android, we implement 3D lunar mesh model construction, lunar texture and mapping, GPU shader illumination programming, multi-level terrain labels and interactive browsing. In particular, a technique of terrain labels for mobile device is presented by developing a vertex shader and fragment shader which is dedicated to render texture, where the vertex shader is mainly used to determine the vertex’s position attribute of the texture while the fragment shader is responsible for the color, font and transparency of the text, etc. The developed browsing system can be rendered on mobile device in real-time.
