NettetSpherical geometry regularizes plane geometry in several ways. First, it elminates parallel lines: now every two lines intersect in a point, and every two points define a line … Nettet7 timer siden · Bell XR Spherical Road Helmet bottom line. The XR Spherical All-Road would be a more suitable title for this helmet, because it was away from the tarmac where I enjoyed it most.

NettetAbout 1830 the Estonian mathematician Ferdinand Minding defined a curve on a surface to be a geodesic if it is intrinsically straight—that is, if there is no identifiable curvature from within the surface. A major task of differential geometry is to determine the geodesics on a surface. The great circles are the geodesics on a sphere.

Great Circle -- from Wolfram MathWorld
Nettet29. jul. 2014 · I think the easiest way to control points on a sphere is by using spherical coordinates. Then you can control position of points around the sphere by using two angles (rho and phi) and the radius. Example code for filling points uniformly around a rotating sphere (for fun): Nettet2. feb. 2015 · To draw the rest of the sphere, I observed and recorded patterns of rotated spheres in the program I wrote. Lines for XY, YZ and XZ planes become ellipses on a sphere after a rotation. NettetThe length of the shortest line between two points on the sphere is the length of a minor arc of a great circle passing through these two points. The spherical distance calculator between two points on the earth provides simple and convenient distance calculation, and can quickly calculate the distance result according to different values of latitude, … maxfli weighted swing trainer
