Andrew Tridgell	c7d5f06b21	AP_Math: added quaternion helper functions and a test suite	2012-03-10 10:34:30 +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
