Cartesian Coordinates

GeographicLib is a small, handy set of C++ classes specially designed to help you convert between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates, for geoid calculations, and for computing geodesic. The emphasis is on returning accurate results with errors close to... Platforms: Windows

This code takes an input of a set of given (x,y) points in the Cartesian coordinates and returns the center and radius of the minimum circle enclosing the points.This code is based on that of Yazan Ahed, and contains no changes in the algorithm but only in the structure.The previous code was... Platforms: Matlab

A variation of Matlab's cart2sph, that transforms a vector of Cartesian coordinates (East, North, Up) to radar coordinates (Range, Azimuth, Elevation). Note the different definition of radar coords vs. spherical coords, which require this different function (see exact definitions within the help... Platforms: Matlab

This code takes an expression for a normalized AF in spherical coordinates and creates a 3D plot in cartesian coordinates. Examples are specific to Antenna Theory and Design (2nd Ed) by Stutzman and Thiele. Platforms: Matlab

Easy-to-use 3D grapher that plots high quality graphs for 2D and 3D functions and coordinates tables. Graphing equations is as easy as typing them down. Graphs are beautifully rendered with gradual colors and lighting and reflection effects. Both cartesian and polar coordinates are supported as...

SHPATH - shortest path with obstacle avoidance (ver 1.3) Given a "terrain" matrix consisting of zeros (for open space) and ones (for obstacles), this function computes the shortest path between two specified points while avoiding obstacles.A two-stage solution is employed. In stage one, the... Platforms: Matlab

Conversion routines to take a surface (a function z of (x,y) or (theta,r)) and convert this into a solid; much as meshz does, but a little more useful for outputting as an STL for frabrication in a 3D printer. There are two cases, one in Cartesian co-ordinates, and the other in polar... Platforms: Matlab

Formulas Rendering Plug-In for the Gimp 2 is a simple plugin that allows you to change the values of each color channel of each pixel of a layer by using mathematical expressions. It is able to handle RGB* and Gray* images. Available operators are: +, -, *, /, ^, and %. There are many functions... Platforms: *nix

CoordinatesX is an application that transforms geodetic and Cartesian coordinates. It will make the conversions from Geodetic latitude, longitude and heights to planet centered Cartesian coordinates and vice versa. Works for various planetary ellipsoids, including user defined... Platforms: Mac

Special Effects is a simple application designed using Java that allows you to add special optical effects. You can add effects like seeing through glass sphere, water droplets or swirl effect with varying degree of radial changes. You can also create 3-D perspective effects with the images,...

MacMolPlt is a Chemistry visualization tool that can be used to build molecules with an integrated graphical model builder, create input files for the GAMESS computational chemistry program, and then visualize the results of computational chemistry runs. Features include a high-quality 3D... Platforms: Mac

The function assumes the WGS84 model.Latitude is customary geodetic (not geocentric).Inputs may be scalars, vectors, or matrices of the same size and shape. Outputs will have that same size and shape.Usage[lat,lon,alt] = ecef2lla(x,y,z)lat = geodetic latitude (radians)lon = longitude (radians)alt... Platforms: Windows, Mac, *nix, Matlab, Solaris

moonpos calculates the moon position using the method in the bookAstronomical Algorithms by Jean Meeus, Chapter 45, pp 307 - 313. Thealgorithm used is accurate to about 10 arcsec in longitude and 4 arcsecin latitude according to the book, although the time range is notmentioned. The periodic... Platforms: Matlab

This block allows the use of aeronautics conventions to express orientation and position of an object in a virtual world.Specifically, the object's orientation can be expressed by means of euler angles and its position by means of X,Y,and H cartesian coordinates.October 2002Giampiero Campa,...

GeographicLib is a small set of C++ classes for performing conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates, for gravity (e.g., EGM2008), geoid height, and geomagnetic field (e.g., WMM2010) calculations, and for solving geodesic problems. It is a... Platforms: *nix
