Methods

Modifier and Type	Method and Description
Vector	add(Vector v) Adds the given vector to this vector
Vector	cpy()
Type	dot(Vector v)
Type	len()
Type	len2() This method is faster than Vector.len() because it avoids calculating a square root.
Vector	nor() Normalizes this vector.
Vector	scl(Type scalar) Scales this vector by a scalar
Vector	set(Vector v) Sets this vector from the given vector
Vector	sub(Vector v) Subtracts the given vector from this vector.

Method Detail

cpy

Vector cpy()

Returns:

a copy of this vector

len

Type len()

Returns:

The euclidean length

len2

Type len2()

This method is faster than Vector.len() because it avoids calculating a square root. It is useful for comparisons, but not for getting exact lengths, as the return value is the square of the actual length.

Returns:

The squared euclidean length

set

Vector set(Vector v)

Sets this vector from the given vector

Parameters:

v - The vector

Returns:

This vector for chaining

sub

Vector sub(Vector v)

Subtracts the given vector from this vector.

Parameters:

v - The vector

Returns:

This vector for chaining

nor

Vector nor()

Normalizes this vector. Does nothing if it is zero.

Returns:

This vector for chaining

add

Vector add(Vector v)

Adds the given vector to this vector

Parameters:

v - The vector

Returns:

This vector for chaining

dot

Type dot(Vector v)

Parameters:

v - The other vector

Returns:

The dot product between this and the other vector

scl

Vector scl(Type scalar)

Scales this vector by a scalar

Parameters:

scalar - The scalar

Returns:

This vector for chaining
