Peter Barker	36fe9a18a0	AP_Math: make Polygon_outside cope with being passed unclosed polygons	2019-05-29 15:34:02 +10:00
Peter Barker	51a0401383	AP_Math: correct Polygon_outside floating point instatiation ... This routine was entemplatificated from the integer version, which was designed to be perfect across representable ranges of points. The floating point version suffered from a rounding problem.	2019-05-28 09:08:07 +10:00
Peter Barker	f09efe0908	AP_Math: correct URL for Polygon_outside algorithm	2019-05-24 13:17:43 +10:00
Peter Barker	b22d3a0103	AP_Math: avoid casting floats to int32's for temporary variables ... Note the use of 64-bit integer arithmetic further down, however	2019-04-23 09:36:17 +10:00
khancyr	15398f8b0e	AP_Math: correct variable init and remove define in polygon	2017-07-31 17:35:08 +09:00
Pierre Kancir	6bf1322633	AP_Math: polygon.cpp correct float comparison	2016-12-06 09:31:21 -08:00
Mathieu OTHACEHE	152edf7189	Global: remove mode line from headers ... Using a global .dir-locals.el file is a better alternative than reincluding the same emacs header in every file of the project.	2016-10-24 09:42:01 -02:00
Daniel Ricketts	249d95b413	AP_Math: add Polygon_outside and Polygon_complete functions	2016-06-25 15:55:55 +09:00

Andrew Tridgell	11b8d56434	added comment in polygon code	2011-12-21 23:31:38 +11:00
Andrew Tridgell	6efa2e53cb	AP_Math: re-work polygon algorithm for perfect precision ... using sign checking and 64 bit integer math only when needed results in an algorithm that is just as fast as the floating point version, but has perfect results for any representable lat/lng	2011-12-19 18:52:56 +11:00
Andrew Tridgell	a3a0e5646f	polygon: improve the speed and precision of the polygon algorithm ... now takes 156 usec per test, with a 11 point boundary	2011-12-18 12:59:50 +11:00
Andrew Tridgell	42522baf9f	geofence: store fence points as int32_t ... this keeps maximum precision in fence boundaries	2011-12-16 20:11:51 +11:00
Andrew Tridgell	9b6bab8904	AP_Math: better polygon algorithm ... this one seems to do better with single precision floating point	2011-12-16 20:11:51 +11:00
Andrew Tridgell	85e295332f	AP_Math: added Polygon_complete() function ... used to veryify user supplied boundaries	2011-12-15 14:42:34 +11:00
Andrew Tridgell	117a98f9a2	AP_Math: added a Polygon_outside() function ... this tests if a point is outside of a polygon. This will be used as part of our geo-fencing support, and also for a new 'fenced mode'	2011-12-15 14:34:58 +11:00
