This is why the position attributes are linked in Earth Studio-they're entirely codependent. Right: Logarithmic altitude with adjustments applied to lat / long Left: Camera move with logarithmic altitude, but linear lat / long But just a few hundred meters from the ground? Not a pleasant sensation. Imagine moving thousands of kilometers a second over the Earth. A visually "linear" descent to Earth reveals the magnitude of any lateral changes (longitude and latitude). Unfortunately, altitude isn't the only factor when creating perceptually smooth large-scale animations. This way, it's easier to understand how attributes are being affected so you can adjust accordingly.
When planning such a move, be sure to enable Logarithmic Altitude before you start animating. For other projects, you'll have to manually enable it in the Animation > Advanced menu.Īs explained above, Logarithmic Altitude is a necessity when animating over massive changes in altitude. In Quick Start projects, Earth Studio automatically detects when Logarithmic Altitude is needed and enables it accordingly. More advanced usage reveals a few shortcomings and considerations, which will be covered below.
Right: An adjusted logarithmic move that we perceive as linear.įor simple moves, Logarithmic Altitude is highly effective. Left: An unadjusted, linear camera move that looks like it's speeding up. The resulting motion compensates for our perceptual deficiencies and appears perfectly linear / constant. It's called logarithmic because Earth Studio uses a near-logarithmic formula to calculate these changes. When enabled, logarithmic altitude will move the camera faster out in space and slower as it approaches the Earth. Our brains take this to assume we're moving faster.Įarth Studio offers an experimental feature called Logarithmic Altitude to counteract the speeding-up effect. This is an issue of human perception-our points of reference on the Earth seem to scale much more dramatically as we near the surface. OverviewĪ camera, moving at a constant speed towards Earth, will seem to move much faster the closer it gets to Earth. We counteract these issues with a feature called Logarithmic Altitude. Predictably, this raises some issues in the context of animation.

Elizabeth first got interested in space after watching the movie Apollo 13 in 1996, and still wants to be an astronaut someday.Earth Studio requires us to deal with massive changes in scale. Elizabeth is also a post-secondary instructor in communications and science at several institutions since 2015 her experience includes developing and teaching an astronomy course at Canada's Algonquin College (with Indigenous content as well) to more than 1,000 students since 2020. in Space Studies from the University of North Dakota, a Bachelor of Journalism from Canada's Carleton University and a Bachelor of History from Canada's Athabasca University. Her latest book, " Why Am I Taller?", is co-written with astronaut Dave Williams. Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, flying parabolic, working inside a spacesuit, and participating in a simulated Mars mission. She was contributing writer for for 10 years before joining full-time. Įlizabeth Howell (she/her), Ph.D., is a staff writer in the spaceflight channel since 2022 covering diversity, education and gaming as well. Its images so far include a view of the farthest star we've seen to date (it's called Earendel, a "Lord of the Rings" reference), a haunting "Phantom Galaxy" and the deepest view of the universe we've ever seen.įollow Elizabeth Howell on Twitter. 25, 2021, and wrapped up its commissioning period last month. Webb has already reached far into the universe, even though the observatory has only been fully operational for a few weeks. "However, this snapshot provides perspective on what happened to the galaxy in the past and what it will do in the future." "The form that the Cartwheel Galaxy will eventually take, given these two competing forces, is still a mystery," ESA officials wrote.
