Point3i class
An immutable point with X, Y and Z as integer values.
Constructors
- Point3i({required int x, required int y, int z = 0})
-
A point at given x, y and z (z is zero by default).
const
- Point3i.create({required num x, required num y, num? z, num? m})
- A point from parameters compatible with CreatePosition function type.
-
Point3i.from(Iterable<
num> coords, {int? offset}) -
A point from
coords
given in order x, y, z.factory - Point3i.fromText(String text, {Pattern? delimiter})
-
A point parsed from
text
with coordinates given in order: x, y, z.factory - Point3i.origin()
-
A point at the origin (0, 0, 0).
const
- Point3i.parse(String text, {ParseCoordsInt? parser})
-
A point parsed from
text
with coordinates in order: x, y, z.factory - Point3i.xyz(int x, int y, int z)
-
A point with coordinates given in order: x, y, z.
