    Volume Visualization of the Orion Nebula

  • San Diego Supercomputer Center


    In this visualization, viewers are transported 1,500 light years to the heart of the Orion Nebula. The nebula is derived from a 3D polygonal model based on radio and visible light observations from the Hubble Space Telescope and ground-based observations. A custom toolkit converts this polygonal model to 3D volume data with accurate and controllable nebulosity rendition of the various depicted forms. Eighty-four additional volumes were modeled and placed into the scene with 883 stars, using Gaussian footprints for star brightness. The animation was created using custom volume-rendering software that renders multiple, multi-resolution volumes using perspective viewing transformations.
