2. About the 4D2U Project
The project's goal is to visualize astronomical data in a way that helps watchers feel as if they are witnessing the unfolding of the universe.
"Four dimensions" refer to the three dimensions of space and the one dimension of time embedded in their data.
"Digital" refers to computer graphics visualizations of digital data.
The resulting acronym is "4D2U", and it is also astronomy's way of saying "4D to you."
For astronomers, the goal is to provide a rare 3D view of data to help with research.
Unrestricted explorations in 3D are essential tools for understanding modern observational data and computer simulations.

3. Background of Project
Massive amounts of digital image data gained by world class observation instruments such as Subaru Telescope、 ALMA Project and ‘Hinode’ etc.
Large astronomical simulation data
Wide adoption of broadband
Higher Accountability required for research

22. Science is Culture. Let’ go to the 4D theater !
Let's aim at promotion of the science
　　　　　　 to make people happy.
For this purpose,
　　 Education and Popularization
is important．
Let’ go to the 4D theater !
