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

・Reconstructing the latest scientific knowledge
within the contrast (space scale) of over 40 digits
・Using real science and simulation
・Enjoyment, depth, and purpose of science
Utilization in other fields
• Biology
• Molecule science
• Science dealing with other complex
system.
(Nuclear Fusion etc.)
• Cultural treasures
Science is Culture.
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 !
