Constructor and Destructor
o CAT3DArcEllipseGP
| public CAT3DArcEllipseGP( | ) |
-
Constructs an empty 3D Arc Ellipse dynamic graphic primitive.
o CAT3DArcEllipseGP
| public CAT3DArcEllipseGP( | const | iCenter, |
| const | iNormal, |
| const | iXRadius, |
| const | iYRadius, |

-
Constructs a 3D ellipse arc or a 3D ellipse graphic primitive
- Parameters:
-
- iCenter
- The center of the ellipse arc.
- iNormal
- The normal to the ellipse plan.
This vector must be normalized
- iXRadius
- The ellipse arc radius in the reference axis direction.
- iYRadius
- The ellipse arc radius in the reference axis normal direction
- iReferenceAxis
- The reference axis.
It is in the ellipse plan.
- iStartAngle
- The start angle of the arc with
respect to the reference axis.
Legal values: The default start angle value
is 0.
- iEndAngle
- The end angle of the arc with
respect to the reference axis.
Legal values: The default end angle value
is 360 degrees.
- iStaticSagUsed
- Used to specify whether using a dynamic or a static
sag for the ellipse arc visualization.
Legal values:
- 1
- The sag value is static and taken
from the settings, and is constant whatever the distance between
the view point and the ellipse arc may be
- 0
- The sag value is dynamic and calculated depending on
the distance between the view point and the ellipse arc
Methods
o ImmediateDraw
| public virtual ImmediateDraw( | | iRender, |

-
Draws the ellipse arc.
- Parameters:
-
- iRender

o Modify
| public Modify( | const | iCenter, |
| const | iMajorRadius, |
| const | iMinorRadius, |
| const | iStartAngle, |
| const | iEndAngle) |
-
