Detailed Description

Ellipse object.

var center = new GO2SXYZ(50,50,0)
var pMajor = new GO2SXYZ(120,60,0)
var pMinor = new GO2SXYZ(40, 40, 0)
var ellipse = new GO2SEllipse(center, pMajor, pMinor)
center = new GO2SXYZ(-50,-50,0)
var aMajor = new GO2SXYZ(0.707,0.707,0)
pMajor = center.Added(aMajor)
var z = new GO2SXYZ(0,0,1)
var aMinor = aMajor.CrossProduct(z)
pMinor = center.Added(aMinor)
ellipse = new GO2SEllipse(center, pMajor, pMinor)
ellipse.SetParam(GO2SParam.length, 100)
ellipse.SetParam(GO2SParam.width, 50)
Remarks
GO2SParam::length is the major radius, GO2SParam::width is the minor radius

Member Function Documentation

◆ SetFrom3Points()

GO2SEnum::GO2SError GO2SEllipse::SetFrom3Points ( GO2SXYZ center,
GO2SXYZ pMajor,
GO2SXYZ pMinor )

Create an ellipse from 3 points defining center, major and minor radius

Returns
GO2SError.success (0) if success, see GO2SError otherwise
Parameters
[in]centerthe center of the ellipse
[in]pMajora point defining both the major axis and the major radius
[in]pMinora point defining the minor radius. This point is not obligatorily in the minor axis but its projection distance on the major axis gives the minor radius
