| Jun 10, 2015 at 17:32 | comment | added | talrnu | @Pharap Here's a fun example: moillusions.com/wp-content/uploads/i207.photobucket.com/albums/… In addition to having a better focal length, this one also animates back and forth more rapidly, so the illusion is much more effective. | |
| Jun 10, 2015 at 17:16 | comment | added | Pharap | @talrnu Is there a better example somewhere? At the moment I can't see this 'trick' working. | |
| Jun 10, 2015 at 14:03 | comment | added | talrnu | @Pharap This style of animation is designed to present an image in a 2D plane in a way that "tricks" the brain into seeing it as a 3D image. There's certainly value in the full rotation you mention, it just doesn't have the same effect as this style of animation intends. | |

Shima and Pareah in the green area also seem to be slightly further away, as does Wolf-Reiser in the blue. I imagine this map's side-on view being relatively flat with the exception of those four stars. ;) | |
| Jun 9, 2015 at 18:38 | comment | added | Pharap | @talrnu If that is the graphic's intent, it might as well make a full rotation around the group of planets being mapped to use their scale to represent distance. That would be using 3D projection though, which also violates the OP's "without [...] showing the entire setup from some angle. This needs to be viewed only from the top down." rule. I think animation would probably violate the restrictions anyway. | |
| Jun 9, 2015 at 17:06 | comment | added | talrnu | @Pharap That animation appears to use too large a focal length, causing all of the stars to appear to be roughly the same distance from the viewer and therefore making it difficult to fully comprehend their different depths. You'd want to make this kind of animation with a short focal length such that the farthest star appears not to move at all, and the nearest star moves dramatically. Unfortunately, this isn't an accurate way to depict depths on a map, and doesn't satisfy the asker's requirement for a 2D map from the top down. | |
