• Volume Control
  December 22, 2022 by J. Douglas Patterson#audio, #mute button, #volume control

  One of the issues with this and other of my astronomy tutorials is that the sound effects could be a bit loud and jarring. I've moved away from the keyclick sound for button presses to a softer "bomp"... Continue reading

  In working with this tool this semester, I noticed a couple of places where the sim didn't work exactly like I wanted it to. As next semester looms and my Winter Break to-do list begins to fill, I th... Continue reading

  What Was Missing The core mechanics of this simulation I feel are solid and therefore I did not make any changes to the physics. What was cumbersome and incomplete was the user interface. It wasn't... Continue reading

  
• New UI With Physical Units
  October 14, 2019 by J. Douglas Patterson

  For a long while now, I've liked the initial development of this demo as a way of demonstrating Kepler's First and Second Laws of Planetary Motion, but it lacked the ability to demonstrate the third l... Continue reading
• Kepler's 2nd Law Feature
  September 08, 2019 by J. Douglas Patterson#Keplers2ndLaw, #UI, #Swept Area

  As part of the continuing evolution of this demo of orbital motion, I've included a system that shows the area swept by a line from the planet to the orbiting moon over a half second of simulation tim... Continue reading

  
• Added Camera Motion
  September 02, 2019 by J. Douglas Patterson

  This most recent update reorganizes the UI in what I hope is a more sensible fashion. I also added a Sun feature and the ability to rotate the camera view about the scene. The camera distance remain... Continue reading
• Now with data!
  August 31, 2019 by J. Douglas Patterson

  To aid in the discussion of orbital mechanics and orbital energies, I've included several additional fields listing various orbital energy and geometry parameters. Orbital Energy All orbital energies... Continue reading
