Class Point3f
extends Object
A 3D point with coordinates represented as floats.
Points are immutable.
Constructors
Creates a point from x, y, and z.
Statics
Deserializes bytes into a point instance.
Methods
Returns a copy of this instance with negated coordinates (that is (-x, -y, -z)).
Subtracts this instance from the other and returns the result (that is (x - other.x, y - other.y, z - other.z)).
Multiplies this instance with the other and returns the result.
The other can be a scalar or another point.
If the other is a point, then multiplication is done per coordinate (that is (x * other.x, y * other.y, z * other.z)).
If the other is a scalar, then each coordinate is multiplied (that is (x * other, y * other, z * other)).
Divides this instance with the other and returns the result.
The other can be a point or a scalar.
If the other is a point, then the division is done per coordinate (that is (x / other.x, y / other.y, z / other.z)).
If the other is a scalar, then each coordinate is divided by the scalar (that is (x / other, y / other, z / other)).
Adds this instance to the other and returns the result (that is (x + other.x, y + other.y, z + other.z)).
Whether this object is equal to the other.
Inheritance
Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:
class Pin:
number/int
constructor .number:
operator == other:
if other is not Pin: return false
return number == other.number
A class doesn't have to follow the above format, but it must keep the operator in sync with any
hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).The serialization format is not stable.
