add clj/s

(add [x1 y1] [x2 y2])

Add two vectors

dist clj/s

(dist v1 v2)

Gets the distance between two vectors

dot clj/s

(dot [x1 y1] [x2 y2])

Dot product of two vectors

lerp clj/s

(lerp v1 v2 t)

Linear interpolation between two vectors

mag clj/s

(mag v)

Get the magnitude of a vector

midpoint clj/s

(midpoint v1 v2)

Gets the midpoint of two vectors

normal clj/s

(normal [x y])

Get the normal vector of a vector

normalize clj/s

(normalize v)

Return a normalized version of a vector

rotate clj/s

(rotate [x y] a)

Rotates a vector around the origin. Shorthand for a rotation matrix.

rotate-about clj/s

(rotate-about v cp a)

Rotates a vector around a given point.
