This study introduces a novel architecture for visualizing the entire Universe, from human scales to the observable cosmos. It utilizes power scaled coordinates (PSC) for scale-neutral modeling and rendering of astronomical data.

Area of Science:

  • Astronomy and Astrophysics
  • Computer Graphics
  • Scientific Visualization

Background:

  • Modern astronomical instruments generate vast 3D datasets across all scales.
  • Visualizing the Universe presents unique challenges due to its immense scale and sparse nature.
  • Existing 3D graphics frameworks are not optimized for astronomical visualization scales.

Purpose of the Study:

  • To introduce a comprehensive architecture for scale-neutral visualization of the physical Universe.
  • To address the limitations of conventional graphics frameworks in handling astronomical data scales.
  • To develop methods for interactive visualization across a wide range of cosmic scales.

Main Methods:

  • Developed a novel architecture encompassing the entire Universe with scale-neutrality.
