GeometricObjects Interface CATPEllipse
Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATPEllipse
Interface representing an ellipse in the space of a surface.
The CATPEllipse is created by the CreatePEllipse
method of the CATGeoFactory interface
and deleted with the Remove method.
A CATPEllipse is defined with:
| CATSurface | Sur |
The underlying surface |
| double | A |
The half length of the major axis |
| double | B |
The half length of minor axis |
| CATAngle | iOffset |
The angle between the surface first direction and the
major axis |
| CATAngle | iStart |
The low angle limitation |
| CATAngle | iEnd |
The high angle limitation |
with 0 <= iStart < CAT2PI,
iStart < iEnd <= iStart + CAT2PI, B <= A.
The iStart and iEnd angles are measured
from the major axis.
The parametric equation of the ellipse in the surface is:
U=a*cos(theta), V=b*sin(theta).
Notice that the CATSurParam associated with (U,V)
may not correspond to theta. So, do not make any assumption on the
internal ellipse parameterization.
The ellipse equation
in its axis system is U²/A² + V²/B² = 1.
