ellipse3D

xyz = ellipse3D(a=1.0, b=a; center=(0.0, 0.0, 0.0), ang1=0.0, ang2=360.0, rot=0.0, e=0.0, f=0.0, plane=:xy, is2D=false, np=72)::Matrix{Float64}

Create an ellipse in 2D or 3D space. Attention, this is a 2D body, not an ellipsoid.

Args

• a: The semi-major axis length of the ellipse.

• b: The semi-minor axis length of the ellipse. Defaults to a if not provided (that is, a circle).

Kwargs

• center: A 3-element array or tuple defining the center of the ellipse.

• ang1: The starting angle of the ellipse in degrees.

• ang2: The ending angle of the ellipse in degrees.

• rot: The rotation angle of the ellipse in degrees. Positive means counterclockwise.

• e: The eccentricity of the ellipse, between 0 and 1.

• f: The flattening of the ellipse, defined as (a-b)/a.

• plane: The plane in which to create the ellipse, one of :xy, :xz, or :yz.

• is2D: If true, create a 2D ellipse (no z-coordinate).

• np: The number of points to use to define the ellipse.

Returns

A matrix of points defining the ellipse, with each row representing a point in 3D space.
