What kind of angles are used.

It seems to be 0-0.5 is eqal to 0-180Ã‚Â° or 0-pi ?

Why is it used like that and who started this system??

one is one revolution.

so 0.5 is indeed 180degrees or pi if you´re used to radians.

not using a separate system for angular values makes simple patches much simpler, its for the same reason an object starts with width and height one in the middle of the world. one will rotate it one around. frac is your friend.

advanced users, who are used to sin() and cos() functions might need to throw a pi in here and there, but thats easy when you know what to do.

one is one revolution.

yea, scaling everything to one is the best that can be done … i really love it ! think of the formulas from degree to radians or the way back:

(AngleDegree/360)*2Pi = AngleRadian

or:

(AngleRadian/2Pi)*360 = AngleDegree

the quotient inside the brackets, (degree/360) and (radians/2Pi), are a function, which scales the input value into the range of one by dividing the value by its own range, after this the value is multiplied by the new range. this means the range from 0…1 is a reference range that shows the real division a vaule has in its own range. so the formulas are simpler in vvvv:

AngleVvvv*360 = AngleDegree

AngleVvvv*2Pi = AnleRadian

and:

AngleDegree/360 = AngleVvvv

AngleRadian/2Pi = AngleVvvv

advanced users, who are used to sin() and cos() functions might need to throw a pi in here and there

if you need a Pi go here or use the simple term PI in Expr (Value)
