Matrix3d Help.

Anonymous — Fri, 06 Jul 2012 16:51:11 GMT

I'm trying to Align the Z Axis with 2 points, that works but I'm 90deg off around the Z Axis any help would be appreciated

Shared Function UCSAlignZaxix(ByVal Point1 As Point3d, ByVal Point2 As Point3d) As Matrix3d

Try
Dim ZAxis As Vector3d = Point1.GetVectorTo(Point2).GetNormal
Dim yAxis As Vector3d = ZAxis.GetPerpendicularVector.GetNormal
Dim xAxis As Vector3d = yAxis.CrossProduct(ZAxis).GetNormal

Dim NewMatrix3d As Matrix3d = Matrix3d.AlignCoordinateSystem(Point3d.Origin, Vector3d.XAxis, Vector3d.YAxis, Vector3d.ZAxis, Point1, xAxis, yAxis, ZAxis)

Return NewMatrix3d
Catch
Return Nothing
End Try
End Function

got it working

Dim ZAxis AsVector3d= Point1.GetVectorTo(Point2).GetNormal

Dim XAxis AsVector3d= ZAxis.GetPerpendicularVector.GetNormal

Dim YAxis AsVector3d = ZAxis.CrossProduct(XAxis).GetNormal
