public static Line FromRTheta( float radius, float theta )
Public Shared Function FromRTheta ( radius As Single, theta As Single ) As Line
|Thrown if radius is negative.|
radius is the minimum distance from the origin to the line, and theta is the counterclockwise rotation from the positive X axis to the vector through the origin and normal to the line.
This means that if theta is in [0,180), the point on the line closest to the origin is on the positive X or Y axes, or in quadrants I or II. Likewise, if theta is in [180,360), the point on the line closest to the origin is on the negative X or Y axes, or in quadrants III or IV.
