2. Purpose We have performed UNIVERSE Liveshow Gravitational lens effect Simulator Intersteller flythrough ( HippLiner )

3. Motivation Needs to think further questions How are rays bended near the blackhole?How are rays bended near the blackhole? (Gravitational lens effect Simulator) Are there extra solar planets in destination?Are there extra solar planets in destination?(HippLiner) Needs to think further questions How are rays bended near the blackhole?How are rays bended near the blackhole? (Gravitational lens effect Simulator) Are there extra solar planets in destination?Are there extra solar planets in destination?(HippLiner) Develop the new add-on programs.

6. Exsoplanet Simulator –Wakusei guruguru- User Interface Lua-interpreter Scripting Engine Guruguru-Engine Rendering Calculating orbits etc… OpenGL/GLUT Contains programable Scripting engine --Lua language-- Very high flexibility Exoplanet catalog itself is described in Lua. User can add arbitary functions. Updating of exoplanet system catalog: CSV File Lua Catalogs 51Peg.lua Glese876.lua HD177830.lua etc… Converter & Generator Perl script http://exoplanet.eu/

7. Conclusion We devloped a raytrace simulator based on General Relativity for UNIVERSE Liveshow. It is very instructive to show ray trails near a blackhole. We developed an extra solar system simulator. It is very effective to imagine a travel to exoplanets with Interstellar spaceship simulator HippLiner.
