Triangle 2

TriSph is a program that allows you to solve spherical triangles. Let give 3 elements of the triangle, side or angle, and TriSph will compute all the other values. A configuration file, which may be modified by the user, enables to adapt the triangle solution to different practical applications. The configuration file supplied with TriSph includes the principal spherical triangles used in gnomonics (see the documentation).

TriSph integrates 3 complementary modules that satisfy the same logic as TriSph; i.e. if a sufficient number of parameters are given, whatever they are, the module calculates the other parameters. These modules are:

This new version is multilingual and corrects some minor bugs.

TriSph is an open source software under MIT licence. Moreover, TriSph is compiled under Lazarus, a cross-platform compiler, which allows it to be ported to GNU / Linux and Mac OS X.

Despite all the care taken to verify this program, it is possible that some bugs have escaped my attention. If you find any malfunction, do not hesitate to let me know: I shall endeavor to make the necessary changes. I will also be very attentive to proposals from users for improving the program if they express a particular need (ymassearobasegnomonique.fr).

Have a good use!...
