Today i tried to fly over the geographical North Pole in FlightGear and found the following bugs.
1. There were some bugs with the scenery alignment, Just take a look at these pictures: Here we have a long ditch on the ocean floor. http://tinypic.com/view.html?pic=1fd2fq When we fly a little farther into the northern direction we have a big hole at around 88*58.502 N on the ocean floor: http://tinypic.com/view.html?pic=1fd2mt I also want to mention, that there is no ice visible at the North Pole. BTW: It would also be a good idea to have polar lights. 2. When reaching waypoint 90*00.000 N the sun plays crazy. I know, in winter it shouldn't be possible to see the sun at the North Pole at day time but because of the big hole in the ocean (see above) it was possible to see what happens with the sun. It flys around the center of my view point. This shouldn't happen, Maybe it is better to use a spherical model for the sun and stars instead of a sky dome or by making he sun the center of the 3d world (in other words using 3 coordinate systems instead of 2. One coordinate system for the sun as a center of the solar system, one planet coordinate system and one local coordinate system to avoid floating point precision problems) Is this technically possible? 3. When trying to fly straight over the North Pole (waypoint 90*00.000 N) the latitude co-ordinate freezes instead of counting backwards. And the longitude runs in a cycle trying to find the correct co-ordinate. So it was not possible to fly over the North Pole, the only thing that worked was to turn the ufo 180 degrees and fly back. Then i also have a question, what co-ordinates are used for the "magnetic" North Pole in FlightGear? Is this implemented?
