PlottableSpaceCurveCategory is the category of curves in 3-space which may be plotted via the graphics facilities. Functions are provided for obtaining lists of lists of points, representing the branches of the curve, and for determining the ranges of the `x-`

, `y-`

, and `z`

-coordinates of the points on the curve.

- coerce: % -> OutputForm
from CoercibleTo OutputForm

- listBranches: % -> List List Point DoubleFloat
`listBranches(c)`

returns a list of lists of points, representing the branches of the curve`c`

.

- xRange: % -> Segment DoubleFloat
`xRange(c)`

returns the range of the`x`

-coordinates of the points on the curve`c`

.

- yRange: % -> Segment DoubleFloat
`yRange(c)`

returns the range of the`y`

-coordinates of the points on the curve`c`

.

- zRange: % -> Segment DoubleFloat
`zRange(c)`

returns the range of the`z`

-coordinates of the points on the curve`c`
