Mitaka : The Four-Dimensional Digital Universe Viewer
Movies Based on Observational Data
Zindaiji & Oosawa :
Astronomical Many-body Simulation and Volume Data Visualizer
The 4D2U Project produces movies visualizing observational and computational data. The movies are avairable at the 4D2U website. The following pictures are examples from the movies. Mitaka is software which visualizes the hierarchical structure of the Universe using data obtained from observations and numerical simulations. Users can seamlessly navigate across the Universe from Earth to the edges of the observable Universe. This software can be This stereoscopic lunar surface model is based on data obtained by the laser altimeter (LALT) and the terrain camera (TC) on the lunar orbiter space craft "KAGUYA". (Data provided by JAXA, LISM/TC team and RISE Project, NAOJ.) This video provides a tour of Mars from Mt. Olympus to Valles Marineris. This 3D model of Mars is based on data obtained by the Mars Global Surveyor. (Data provided by MEGDRs.) System Requirements: OS : Windows 8/7/Vista/XP  CPU :  Pentium4 1.8GHz or better  Memory : 512MB or more Graphics Adapter: GeForce3 or better  Display Resolution : 1024 x 768 pixels (XGA) or more Hard Disk Space : 50MB or more This movie shows the results of an extensive many-body simulation which calculates the evolution of the distribution of dark matter from 13 billion years ago to the present. (Data provided by Hideki Yahagi and Masahiro Nagashima.) This movie shows a collision of two disk galaxies which activates star formation and causes the formation of massive star clusters. (Data provided by Hidenori Matsui.) Zindaiji is software for visualizing the data of many-body simulations. Equippted with an intuitive interface, this software can show simulation results from any point of view and produce high quality movies. Oosawa is a GUI front-end tool using Pov-Ray for ray tracing of volume data time series. Users can edit the movies using a timeline. From planetesimals to Earth-like Planets This movie shows the planet formation process, from planetesimals colliding in the protoplanetary disk up to two Earth-like planets. (Data provided by Eiichiro Kokubo and Hidenori Genda.) This video shows how the Moon fromed from a proto-lunar disk created by a collision between the the proto-Earth and another protoplanet. (Data provided by Takaaki Takeda and Robin M. Canup.) The Four-Dimensional Digital Universe (4D2U) Project develops the "4D2U contents" presenting celestial bodies and astronomical phenomena in 4 dimensions (3D spatial dimensions + time). As the name implies, this project aims to bring the Universe in 4D "to you (2U)", using scientifically correct visualizations based on astronomical observations provided by telescopes and numerical simulations provided by supercomputers. The 4D2U contents are useful not only for scientifi c research and education, but also for various roles such as entertainment.

4D2U Dome Theater
The 4D2U Dome Theater at Mitaka Campus, which opened in March 2007, offers a full dome stereoscopic experience. Everybody can enjoy the movie contents presenting the latest astronomical research and/or a journey through the Universe with Mitaka software. The movie contents and the software used in the theater were developed by the 4D2U Project.
