• Image color transfer
  October 30, 2024 by aalberik

  A great solution to increase realism is to copy the look-and-feel of a real camera image which is called image color transfer. The target images are from Images from the Mars Perseverance Rover - NASA... Continue reading

  
• Different Sun shadow penumbra size - different planets
  October 01, 2024 by aalberik

  That's how the distance to Sun affects its shadow: the closer the planet, the bigger the Sun's solid angle and so the penumbra. Example images from Mercury, Mars and Pluto at the same Sun elevation... Continue reading

  
• A new release is on the way
  September 08, 2024 by aalberik

• Khronos PBR Neutral tone mapper
  April 21, 2024 by aalberik

  Demeter now supports the Khronos PBR Neutral tone mapper so you can choose from 8 different tone mappers. Their curves (except LPM) are "brightness-balanced" to the linear one so there's no need camer... Continue reading

  
• Sunrise in space
  April 15, 2024 by aalberik

  April 11, 2024 by aalberik

  Major changes: Celestial settings added to in-game menu Photometric distant stars and improved labeling Sounds can be enabled in vacuum Sol/Pluto + Sol/Pluto/Charon terrain support Experimental Sol/Sa... Continue reading

  
• Photometric distant stars and improved labeling
  April 07, 2024 by aalberik

  Displaying distant stars is a difficult task because their luminance is really high, however, their apparent size is much lesser than a pixel. Some solid angle calculation can give a solution for this... Continue reading

  
• Venus local DEM support
  March 15, 2024 by aalberik

  Screenshots were taken at the center of Aphrodite Terra. Atmosphere density is reduced to reveal of the venusian cloud simulation... Continue reading

  
• Rotor dynamics replaced and Io global DEM added
  March 09, 2024 by aalberik

  The previous rotor dynamics didn't perform as expected so I grabbed a physics book and implemented a rotor model and integrated it into Bullet physics engine. After all there are nice numbers to displ... Continue reading

  
• Stability fix
  February 26, 2024 by aalberik

  Physics simulation could become unstable at high performance load (e.g. astronaut could fall through the terrain). The last patch should fix it (it lets more CPU time for physics calculation in such c... Continue reading
