Module geo_nd::vector

Vector functions module

This module provides numerous N-dimensional vector operations operating on [Num; N] (or [Float; N]).

Functions

add

Add another vector scaled by a value to a vector, returning the sum

axis_of_rotation3

Find the axis of rotation of a Matrix3

clamp

Clamp each element to be between min and max

comp_mult

Consume the vector and return a new vector that is the original scaled in each coordinate a different scale factor

cross_product3

Return the outer product (cross product) of two 3-dimensional vectors

distance

Return the distance between two vectors

distance_sq

Return the distance square between two vectors

dot

Return the inner product (aka dot product or scalar product) of this and another vector

fmt

Format the vector for display

is_zero

Return true if the vector is all zeros

length

Return the length of the vector

length_sq

Return the length^2 of the vector

mix

Find the linear interpolation between two vectors by a parameter t.

normalize

Normalize (make unit length) a vector if possible

reduce

Reduce ever element of a vector by a single scaling factor

rotate_around

Rotate a vector within a plane around a pivot point by the specified angle

scale

Scale ever element of a vector by a single scaling factor

set_zero

Set the vector in-place to be zero

sub

Consume the vector, and return a new vector that is the sum of this and a borrowed other vector scaled

zero

Create a zero vector of the correct size
