4D2U theater at NAOJ 4D Digital Universe Project Today & Future H。idehiko Agata Director of Public Information Office National Astronomical Observatory of Japan　(NAOJ）

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.

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
