Technical Details
This is the dome show component where the CME strikes the Earth.
The domemaster format was created by rendering 7 separate camera tiles. The tiles were then stitched together to form final domemaster layers at 4096x4096 resolution and 16 bits per channel with premultiplied alpha and no gamma correction. There are 2 domemaster layers that should be composited as follows:
- Earth, Sun and particles
- star field (no alpha channel)
In addition to the final domemaster frames and movies, the individual camera tiles are included as well. Each domemaster layer has a set of camera tiles. There are 7 cameras numbered 00 through 06 that represent the itiles. Camera 00 is in the center of the domemaster, camera 01 is looking below camera 00, cameras 01 through 06 look around the outside of the dome master in counter-clockwise order. These frames are probably only useful if a better re-stitching algorithm is ever required to be run on the tiles.",

"description": "Energetic events on the Sun have impacts throughout the Solar System. This visualization, developed for the \"Dynamic Earth\" dome show, opens with a closeup view of the Sun. The solar imagery was collected from the Solar Dynamics Observatory (SDO) using an ultraviolet filter (wavelength 304 Ångstroms or 30.4 nanometers). We can observe jets of ionized gases, called prominences, erupting from the solar surface, and often constrained to loop-shaped trajectories due to the solar magnetic field.We pull out from the Sun to reveal the solar wind, which continuously streams outward from the Sun.We eventually reach the orbit of the planet Venus, the solar wind still streaming around us.But a massive eruption, called a coronal mass ejection, or CME, takes place on the Sun, sending a much higher density of particles (ions and electrons) outward into the solar wind.The wave of particles eventually strikes the planet Venus. But Venus has no significant magnetic field, and the particles make it directly to the atmosphere of the planet. These energetic solar events slowly blow away the atmosphere of the planet.The next part of this sequence is \"The Coronal Mass Ejection strikes the Earth!\".Technical DetailsThis is the dome show component moving from the Sun to Venus being hit by the CME.The domemaster format was created by rendering 7 separate camera tiles. The tiles were then stitched together to form final domemaster layers at 4096x4096 resolution and 16 bits per channel with premultiplied alpha and no gamma correction. There are 3 domemaster layers that should be composited as follows:- Earth and orbits- Sun- star field (no alpha channel)In addition to the final domemaster frames and movies, the individual camera tiles are included as well. Each domemaster layer has a set of camera tiles. There are 7 cameras numbered 00 through 06 that represent the itiles. Camera 00 is in the center of the domemaster, camera 01 is looking below camera 00, cameras 01 through 06 look around the outside of the dome master in counter-clockwise order. These frames are probably only useful if a better re-stitching algorithm is ever required to be run on the tiles. || ",

"description": "A giant explosion of magnetic energy from the sun, called a coronal mass ejection, slams into and is deflected completely by the Earth's powerful magnetic field. The sun also continually sends out streams of light and radiation energy. Earth's atmosphere acts like a radiation shield, blocking quite a bit of this energy.Much of the radiation energy that makes it through is reflected back into space by clouds, ice and snow and the energy that remains helps to drive the Earth system, powering a remarkable planetary engine — the climate. It becomes the energy that feeds swirling wind and ocean currents as cold air and surface waters move toward the equator and warm air and water moves toward the poles — all in an attempt to equalize temperatures around the world.A jury appointed by the National Science Foundation (NSF) and Science magazine has selected \"Excerpt from Dynamic Earth\" as the winner of the 2013 NSF International Science and Engineering Visualization Challenge for the Video category. This animation will be highlighted in the February 2014 special section of Science and will be hosted on ScienceMag.org and NSF.govThis animation was selected for the Computer Animation Festival's Electronic Theater at the Association for Computer Machinery's Special Interest Group on Computer Graphics and Interactive Techniques (SIGGRAPH), a prestigious computer graphics and technical research forum. This is an excerpt from the fulldome, high-resolution show 'Dynamic Earth: Exploring Earth's Climate Engine.' The Dynamic Earth dome show was selected as a finalist in the Jackson Hole Wildlife Film Festival Science Media Awards under the category \"Best Immersive Cinema - Fulldome\". || ",
