Instance Method Details

#lines ⇒ Array<Sevgi::Geometry::Line>

Returns generated grid lines. The memoized collection is frozen and must be treated as immutable.

Returns:

  • (Array<Sevgi::Geometry::Line>) —

    frozen lines



157
 
# File 'lib/sevgi/sundries/grid.rb', line 157

def lines = @lines ||= build.freeze

#points ⇒ Array<Array<Sevgi::Geometry::Point>>

Returns grid line endpoints as points. The outer and nested collections are frozen and must be treated as immutable.

Returns:

  • (Array<Array<Sevgi::Geometry::Point>>) —

    frozen point pairs



152
 
# File 'lib/sevgi/sundries/grid.rb', line 152

def points = @points ||= lines.map { it.points(true).freeze }.freeze

#xys ⇒ Array<Array<Array<Float>>>

Returns grid line endpoints as coordinate pairs. The outer and nested collections are frozen and must be treated as immutable.

Returns:

  • (Array<Array<Array<Float>>>) —

    frozen coordinate pairs
