Factory method to create an arc band.

Create the arc band you need

The angles for the arc band are expressed in degrees counterclockwise from the direction at 3 o'clock). By default, the arc band goes from the start angle to the end angle in the positive direction (counterclockwise). This can changed using the optional angleDirection parameter. To create an arc band from 30 to 145 you can use the following code.

Creation of an arc band is very similar to a circular arc. See GeometryFactory::createCircularArcByCenterPoint. Interpretation based on the coordinate reference

When the passed coordinate reference is a geodetic reference the distance calculations to determine points on the arc band are done using geodesic calculations on the underlying ellipsoid of the coordinate reference. For other coordinate references the distance calculations are done using cartesian calculations.

)
inlinestatic

Factory method to create a circle, given three points.

The points are allowed to have a Z-value, but all Z-values are required to be equal. If this requirement is not met, an exception is thrown. Example usage:

A circle by-3-points where the three points coincide represents a circle with these points as its center and a radius of 0. A circle by-3-points where 2 out of 3 points coincide represents a circle with its center located in the middle between the 2 coinciding points and the other point. A circle by-3-points where the 3 points are co-linear results in luciad::InvalidArgumentException exceptions when curve methods are called in case the coordinate reference is Cartesian . When the passed coordinate reference is a geodetic reference, the distance calculations to determine points on the circle are done using geodesic calculations on the underlying ellipsoid of the coordinate reference. For other coordinate references the distance calculations are done using cartesian calculations.

)
inlinestatic

Factory method to create a circular arc, given three points.

The circular arc will start at the given start point, pass through the given intermediate point and end in the given end point. The points are allowed to have a Z-value, but all Z-values are required to be equal. If this requirement is not met, an exception is thrown. Example usage:

A circular arc-by-3-points where the start, end and intermediate point coincide represents an arc on a circle with these points as its center and a radius of 0. A circular arc-by-3-points where 2 out of 3 points coincide represents an arc on a circle with its center located in the middle between the 2 coinciding points and the other point. If the start and end point coincide, a full circle is drawn, otherwise, the arc is interpreted as half a circle in counterclockwise direction from start to end point. When the passed coordinate reference is a geodetic reference, the distance calculations to determine points on the circular arc are done using geodesic calculations on the underlying ellipsoid of the coordinate reference. For other coordinate references the distance calculations are done using cartesian calculations.

double  bulge 
)
inlinestatic

Factory method to create a circular arc, starting at the given start point and ending in the given end point.

The points are allowed to have a Z-value, but both Z-values are required to be equal. If this requirement is not met, an exception is thrown. Example usage:

The bulge factor is the ratio of (1) the distance between the arc midpoint and the center of the arc's chord, and (2) half the length of the arc's chord. The sign of the bulge indicates whether the midpoint is on the left side (positive) or right side (negative) of the vector from start to end point. So a bulge factor with an absolute value of 1 means a half-circle, smaller than 1 means a less bulging arc and larger than 1 means an arc that bulges out in the start and end point. A circular arc-by-bulge where the start and end point coincide represents an arc on a circle with these points as its center and a radius of 0. The bulge factor is ignored in this case. When the passed coordinate reference is a geodetic reference, the distance calculations to determine points on the circular arc are done using geodesic calculations on the underlying ellipsoid of the coordinate reference. For other coordinate references the distance calculations are done using cartesian calculations.

Factory method to create a circular arc.

Create the circular arc you need

The angles for the circular arc are expressed in degrees counterclockwise from the direction at 3 o'clock. The arc segment goes from the start angle to the end angle in the positive direction (counterclockwise). To create a circular arc with an extent from 45 to 300 you can use the following code.

Arc from 45 to 300

To create a circular arc with an extent from 300 to 45 you can use the following code.

Arc from 300 to 45

Creation of a circular arc with the start and the end angle having the same value results in full circle. Optional orientation of the arc

The default orientation for the circular arc is counterclockwise. The circular arc is a curve that is useful as a sub-curve building block for other geometries, e.g., an arc band. Therefore it also supports the specification of the orientation of the arc. When the orientation value is set to clock-wise the arc segment goes from the start angle to the end angle in counter clock wise direction (negative direction). Interpretation based on the coordinate reference

When the passed coordinate reference is a geodetic reference, the distance calculations to determine points on the circular arc are done using geodesic calculations on the underlying ellipsoid of the coordinate reference. For other coordinate references the distance calculations are done using cartesian calculations.

inlinestatic

Factory to create a polyline to be used as ring.

The polyline represents a closed curve. The implementation does not require the list of points to be such that the first and the last point are the same. A line segment is automatically included between the last point and the first point. Polyline objects can be created with the interpolation types: linear geodesic rhumb

The interpolation types geodesic and rhumb are only allowed for geodetic coordinate references. Creation of a polyline as a ring:

points

the points defining the polyline.

reference

the coordinate reference in which the polyline is defined.

curveInterpolationType

the type of interpolation between the points, i.e., linear, geodesic, or rhumb.

the polyline, as a ring.

luciad::InvalidArgumentException

if the polyline ring cannot be constructed. For example for an invalid combination of coordinate reference and interpolation type.

◆ CreateRoundedPolyline()

System.Collections.Generic.IList< Luciad.Cartesian.Coordinate points,
double  cornerRoundness 
)
inlinestatic

Factory method to create a curve where pointy corners are replaced by Bezier Curves.

This method operates by assuming that the points originally define a Polyline. It retains the first and last point and replaces the geometry around vertex (corners) by a BezierCurve. The extent of BezierCurve depends on cornerRoundess. cornerRoundness decides the size of the Bezier Curve such that lower values will result in more pointy geometries. This method requires at least 3 points to produce a rounded result. If only 2 points are provided, it will return a standard line. If less than 2 points are provided, this method will throw an Invalid Argument exception. If cornerRoundness is zero, a standard Polyline is created. Corner roundness is expected to be between [0,1]. Rounded Line

reference

points

Series of points defining the curve. At least 2 points are required to produce a result.

The lower this value, the pointier the geometry will be. This value must be between [0, 1].

Factory method to create a ring where pointy corners are replaced by Bezier Curves.

This method operates by assuming that the points define a PolylineRing and then replace each corner of the ring by a BezierCurve. The extent of BezierCurve depends on cornerRoundess. CornerRoundness decides the size of the Bezier Curve such that lower values will result in more pointy geometries. This method requires at least 3 points to produce a result. If less than 3 points are provided, it will throw an Invalid Argument exception. If cornerRoundness is zero, a standard PolylineRing is created. Corner roundness is expected to be between [0,1].
