CommandListAppendEllipseRel(Point3D, Double, Double, Double) Method

Marks an elliptical arc from the current position, described by the given parameters and relative center-point coordinates.

Namespace: RAYLASE.SPICE3.ClientLib
Assembly: RAYLASE.SPICE3.ClientLib (in RAYLASE.SPICE3.ClientLib.dll) Version: 3.5.2

Syntax

public void AppendEllipseRel(
	Point3D point,
	double sweep,
	double rotation,
	double ratio
)

point Point3D: The relative coordinates of the center-point.
sweep Double: The parametric ellipse generator value.
rotation Double: The rotation angle of the elliptical arc's x-axis (major) relative to the x-axis of the coordinate system (rad).
ratio Double: The ratio of the elliptical arc's y-axis (minor) to its x-axis (major).

Remarks

Appends a MARK_ELLIPSE_3D_REL command to the list.

The geometry of elliptical arcs, as implemented on the SP-ICE-3 Card, is discussed in 9.1.3 Ellipses.

In 3D, the ellipse describes part of a helical path whose axis of rotation is parallel to the z-axis.

Note that Transformation is only applied to the center point and not to the individual points on the ellipse path.

Example
