This object can also describe a full ellipse if iAlpha = iBeta = 0.
|
Construct unit circle.
|
|
Construct with given parameters.
|
|
Construct an ellipse.
|
|
Construct arc for ellipse defined by m, from begp to endp.
|
|
This doesn't really compute the distance, but a reasonable approximation.
|
|
Like Distance(), but sets pos to point on arc and angle to its angle in arc coordinates. angle and pos are not modified if result is larger than bound. |
|
Return a tight bounding box.
