ECEF2LLA - convert earth-centered earth-fixed (ECEF) cartesian coordinates to latitude, longitude, and altitude. USAGE: [lat,lon,alt] = ecef2lla(x,y,z) lat = geodetic latitude (radians) lon = longitude (radians) alt = height above WGS84 ellipsoid (m) x = ECEF X-coordinate (m) y = ECEF Y-coordinate (m) z = ECEF Z-coordinate (m) Notes: This function assumes the WGS84 model. Latitude is customary geodetic (not geocentric). Michael Kleder, April 2006.

- Descartes
- License: Freeware

Displays graphs of algebraic functions in a variety of forms. These include polar and cartesian co-ordinates, parametric and intrinsic functions. A wide range of functions are built-in, from simple trig and hyperbolic functions to things such as the ceil and gamma functions. On-screen HTML help is bulit-in.
Functions can be defined such as
f(x)= 1 + x
These can be of unlimited complexity, and can refer to other functions such as
g(x) = f(x) + 2*x
Other variables can be set up, so we can define for example
f(x) = m*x + c
and then vary m and c and see the change to the graph.

- Minimum Enclosing Circle
- License: Freeware

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 written based on the very nice Java applet found here: http://heyoka.cs.uiuc.edu/~thite/mincircle/ Credit are due mainly to author of the applet..

- xyz2rae
- License: Freeware

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 comment). input format #1: [...] = xyz2rae(x,y,z) input format #2: [...] = xyz2rae(xyz) output format #1: [range, azimuth, elevation] = xyz2rae(...) output format #2: rae = xyz2rae(...) The input coordinates may be either singular values or a vector of coordinate points. Use the corresponding rae2xyz function for the reverse transformation.

- Cartesian Tensor Face Relighting
- License: Freeware

tensorRelightingDemo.m demonstrates the use of the Cartesian Tensor basis for facial Apparent BRDF (ABRDF) estimation and subsequent relighting. Given a few images of a face under different point source illuminations, the included code for ABRDF estimation can interpolate and extrapolate them to generate new images. Please cite the following paper if you find this code useful: Ritwik Kumar, Angelos Barmpoutis, Arunava Banerjee, Baba C. Vemuri, 'Non-Lambertian Reflectance Modeling and Shape Recovery of Faces using Tensor Splines', IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI), 2009.

- GeographicLib
- License: Freeware

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 round-off (about 5–15 nm). In addition, various properties of the Transverse Mercator Projection are described and an accurate algorithm for Geodesics on the Ellipsoid is given.
