Summary

CURVE Abstract base class for representing line segments and circle arcs

PROPERTIES

  • Curve/left_surface is a property.

  • name - name, Optional

  • pcenter - Center Point of Arc.

  • pend - end Point of curve

  • periodic_with - Another curve that this is periodic with.

  • pstart - start Point of curve

  • Curve/right_surface is a property.

  • type - Type (geo.line or geo.arc)

  • Curve/xend is a property.

  • Curve/xstart is a property.

Methods

Class methods are listed below. Inherited methods are not included.

* Constructor

this = Curve(pstart, pend)

Create a line segment (geo.line) between the Point objects. pstart and pend.

this = Curve(pstart, pcenter, pend)

Create a circle arc (geo.arc) between pstart and pend, centered at pcenter.

* add_to_points Add this to defining Points.

* angle Angle between two Curves.

Call syntax

a = c1.angle(c2)

a = angle(c1, c2)

Returns the angle a.

* Curve/center is a function.

pc = center(this)

* Curve/detach is a function.

detach(this)

* Curve/distance_from_point is a function.

[d, Pclosest] = distance_from_point(this, P)

* == (EQ) Test handle equality.

Handles are equal if they are handles for the same object.

H1 == H2 performs element-wise comparisons between handle arrays H1 and H2. H1 and H2 must be of the same dimensions unless one is a scalar. The result is a logical array of the same dimensions, where each element is an element-wise equality result.

If one of H1 or H2 is scalar, scalar expansion is performed and the result will match the dimensions of the array that is not scalar.

TF = EQ(H1, H2) stores the result in a logical array of the same dimensions.

See also CURVE, CURVE/GE, CURVE/GT, CURVE/LE, CURVE/LT, CURVE/NE Help for Curve/eq is inherited from superclass HANDLE

* Direction of this Curve to join with other curve.

ldir = extend_direction(this, other_curve)

* extends Check if this Curve extends other curve.

bl = extends(this, other_curve, other_curve_direction)

* get_xy Get xy-coordinates of start- and end-points.

* joinable_with Check if this Curve joins with other Curve.

bl = joinable_with(this, other_line)

bl = true if this shares a point with other_line

* ~= (NE) Not equal relation for handles.

Handles are equal if they are handles for the same object and are unequal otherwise.

H1 ~= H2 performs element-wise comparisons between handle arrays H1 and H2. H1 and H2 must be of the same dimensions unless one is a scalar. The result is a logical array of the same dimensions, where each element is an element-wise equality result.

If one of H1 or H2 is scalar, scalar expansion is performed and the result will match the dimensions of the array that is not scalar.

TF = NE(H1, H2) stores the result in a logical array of the same dimensions.

* Curve/next_left is a function.

l = next_left(this, P)

* norm Length of Curve.

* plot Plot Curve.

* Curve/points is a function.

X = points(this)

* rotate Rotate around the origin, return a new Curve.

* Curve/split_with_point is a function.

new_curve = split_with_point(this, P)

* Curve/tangent is a function.

t = tangent(this, p)
