Vec2, Vec3 Classes

• basic arithmetic operators (+-*/) overloaded for other Vec objects or floats
• other helper methods

Non-static Vec2 and Vec3 helpers

func. name	function
toString()/toString(int)	output vector as "(x, y, [z])", can specify number of decimals
length()/lengthSquared()	length/dot product with self

Static Vec2 and Vec3 helpers

func. name	function	note
dot()	dot product between two vectors
distance()/distanceSquared()	length/length squared of (b-a)
reflect()	reflect off surface with given normal	implementation here
refract()	refract through surface with given normal, ratio of IoR's	implementation ^
abs()	all components thru abs()
step()	all components thru step()	identical behavior to here
sign()	all components thru sign()	identical behavior to ^

Static Vec3 specific helpers

func. name	function	note
normalize()	normalize given vector	TODO: for Vec2, too
cross()	cross product of two vectors	implementation here, TODO: handedness specification
min()/max()	all components thru min()/max()	TODO: for Vec2, too
lerp()	all components thru lerp()	TODO: overload for float index, for Vec2, too
pow()	all components thru pow()	TODO: overload for float base/power, for Vec2, too

General TODOs

• testing for Vec3 helper methods
