Catfood Earth v3.10.0236 | 5 Mb
Earth combines satellite images, composite global cloud cover, weather radar, recent earthquake data, the extent of daylight and nighttime, political borders and more to regularly update your wallpaper.
Catfood Earth starts with NASA’s Blue Marble Next Generation images of the Earth’s surface. NASA provides an image for each month. Catfood Earth combines (interpolates) these to create daily images that show snow/ice cover and vegetation growing and dying back throughout the year.
The next layer shows nighttime by calculating the location of the Sun and its height above or below the horizon from the perspective of each pixel on the screen. NASA’s City Lights image is then blended with the Blue Marble layer. You can adjust the transparency of this effect and also the width of shading used to indicate the terminator between day and night.
Lastly clouds are blended with the image. Catfood Earth downloads a global cloud composite image from Xplanet every three hours. The coloring and transparency of the cloud layer are fully adjustable.
The changes are barely perceptible each time Earth updates your wallpaper. Over the course of a year you’ll see the summer and winter solstices (with the longest days in the northern and southern hemispheres) and the vernal and autumnal equinoxes (when the day is approximately the same length everywhere). You’ll also track hurricanes and typhoons as the clouds layer updates.
