Vector3

class Vector3(x, y, z)

Bases: object

Initialize a 3-dimensional vector.

Parameters:

• x (float|int) – The x-component of the vector.

• y (float|int) – The y-component of the vector.

• z (float|int) – The z-component of the vector.

Returns:

None

classmethod from_list(vector)

Create a Vector3 instance from a list of numerical values.

Parameters:

vector (list[float|int]) – A list containing three numeric components [x, y, z].

Return Vector3:

A new Vector3 constructed from the list values.

classmethod right()

Create a right-direction unit vector (1.0, 0.0, 0.0).

Return Vector3:

A unit vector pointing in the positive X direction.

classmethod up()

Create an up-direction unit vector (0.0, 1.0, 0.0).

Return Vector3:

A unit vector pointing in the positive Y direction.

classmethod forward()

Create a forward-direction unit vector (0.0, 0.0, 1.0).

Return Vector3:

A unit vector pointing in the positive Z direction.

classmethod zero()

Create a zero vector (0.0, 0.0, 0.0).

Return Vector3:

A vector with all components set to zero.

classmethod one()

Create a ones vector (1.0, 1.0, 1.0).

Return Vector3:

A vector with all components set to one.

set(x, y, z)

Set all three components of the vector.

Parameters:

• x (int) – The new x-component value.

• y (int) – The new y-component value.

• z (int) – The new z-component value.

Returns:

None

Return type:

None

dot(rhs)

Compute the dot product between this vector and another.

Parameters:

rhs (Vector3) – The vector to compute the dot product with.

Return float|int:

The resulting dot product value.

Raises:

TypeError – If rhs is not a Vector3.

cross(rhs)

Compute the cross product between this vector and another.

Parameters:

rhs (Vector3) – The vector to compute the cross product with.

Return Vector3:

A new vector representing the cross product result.

Raises:

TypeError – If rhs is not a Vector3.

magnitude()

Compute the magnitude (Euclidean length) of the vector.

Return float:

The computed vector magnitude.

normalized()

Return a normalized (unit‑length) version of this vector.

If the vector has zero magnitude, the result is Vector3(0, 0, 0).

Return Vector3:

The normalized vector.

to_list()

Convert the vector into a Python list.

Return list[int|float]:

A list containing [x, y, z].
