Member Function Documentation

Cot()

static double GravityEngine2.GravityMath.Cot ( double x )

static

Cotangent function.

Adapted from Vallado's astmath CPP functions.

Double3IntoVector3()

static void GravityEngine2.GravityMath.Double3IntoVector3 ( double3 r, ref Vector3 v3 )

static

Convert a double3 and fill in values in an existing Vector3 (avoids a new() )

Parameters

r
v3

Double3ToVector3()

static Vector3 GravityEngine2.GravityMath.Double3ToVector3 ( double3 r )

static

Create a Vector3 holding the values of a double3.

Parameters

r

Returns

LatLongToR()

static double3 GravityEngine2.GravityMath.LatLongToR ( double latitudeDeg, double longitudeDeg, double radius )

static

Convert latitude, longitude and radius to a vector.

This has the XY plane as the equator (standard right-handed physics spherical coordinates)

If want display XZ orbital plane will need to flip YZ with one of the '*ExchangeYZ' methods above.

Parameters

latitude	assume North is positive
longitude	assume east is positive
radius

Returns

Rot1()

static double3 GravityEngine2.GravityMath.Rot1 ( double3 v, double angleRad )

static

Return the rotation of the vector v by angleRad radians around the x axis.

Parameters

v
angleRad

Returns

Rot3()

static double3 GravityEngine2.GravityMath.Rot3 ( double3 v, double angleRad )

static

Return the rotation of the vector v by angleRad radians around the z axis.

Parameters

v
angleRad

Returns

Rot3CW()

static double3 GravityEngine2.GravityMath.Rot3CW ( double3 v, double angleRad )

static

Return rotation of vector by angleRad around Z in a clockwise (CW) direction.

Parameters

v
angleRad

Returns
