## Method Descriptions

Returns a Vector3 with the given components.

Returns a new vector with all components in absolute values (i.e. positive).

Returns the minimum angle to the given vector.

Returns the vector “bounced off” from a plane defined by the given normal.

Returns a new vector with all components rounded up.

Returns the cross product with `b`.

Performs a cubic interpolation between vectors `pre_a`, `a`, `b`, `post_b` (`a` is current), by the given amount `t`. `t` is in the range of `0.0 - 1.0`, representing the amount of interpolation.

Returns the normalized vector pointing from this vector to `b`.

Returns the squared distance to `b`. Prefer this function over distance_to if you need to sort vectors or need the squared distance for some formula.

Returns the distance to `b`.

Returns the dot product with `b`.

Returns a new vector with all components rounded down.

Returns the inverse of the vector. This is the same as `Vector3( 1.0 / v.x, 1.0 / v.y, 1.0 / v.z )`.

Returns `true` if this vector and `v` are approximately equal, by running @GDScript.is_equal_approx on each component.

• bool is_normalized ( )

Returns `true` if the vector is normalized.

Returns the vector’s length.

Returns the vector’s length squared. Prefer this function over length if you need to sort vectors or need the squared length for some formula.

Returns the result of the linear interpolation between this vector and `b` by amount `t`. `t` is in the range of `0.0 - 1.0`, representing the amount of interpolation..

• int max_axis ( )

Returns the axis of the vector’s largest value. See `AXIS_*` constants.

• int min_axis ( )

Returns the axis of the vector’s smallest value. See `AXIS_*` constants.

Moves the vector toward `to` by the fixed `delta` amount.

Returns the vector scaled to unit length. Equivalent to `v / v.length()`.

Returns the outer product with `b`.

Returns a vector composed of the `fposmod` of this vector’s components and `mod`.

Returns a vector composed of the `fposmod` of this vector’s components and `modv`’s components.

Returns the vector projected onto the vector `b`.

Returns the vector reflected from a plane defined by the given normal.

Rotates the vector around a given axis by `phi` radians. The axis must be a normalized vector.

Returns the vector with all components rounded to the nearest integer, with halfway cases rounded away from zero.

Returns the vector with each component set to one or negative one, depending on the signs of the components.

Returns the result of spherical linear interpolation between this vector and `b`, by amount `t`. `t` is in the range of `0.0 - 1.0`, representing the amount of interpolation.

Note: Both vectors must be normalized.

Returns the component of the vector along a plane defined by the given normal.

Returns a copy of the vector snapped to the lowest neared multiple.

• Basis to_diagonal_matrix ( )

Returns a diagonal matrix with the vector as main diagonal.
