Sphere

Converts from latitudes and longitudes to a two-dimensional projection well-suited for the visualization of geodesic paths. Here "geodesic paths" refers to paths of shortest distance along the surface of a sphere.

Linearly spaced points between two points in space . This function uses direction vector of two point to calculate points between .zip file containpointsOnLine.m : creates linearly spaced points .testpointsOnLine.m : example showing the use of pointsOnLine function .sphericalDodecahedron.m :...

Given a set of data points, this function calculates the center and radius of the data in a least squared sense. The least squared equations are used to reduce the matrix that is inverted to a 3x3, opposed to doing it directly on the data set. Does not require a large arc or many data points....

The Stellar Aberration 3D Model illustrates the phenomenon known as the aberration of starlight, first reported by James Bradley in 1729. Aberration occurs because light has a finite speed, and thus light from a star takes a finite amount of time to travel through the tube of a telescope. During...

The EJS Parallactic Proper Motion Model illustrates the phenomenon known as parallactic proper motion. Proper motion refers to the progressive (non-oscillatory) apparent motion of a star relative to more distant background stars. If this apparent motion is due to actual motion of the star through...
