Abs colour

The Abs family of nodes allow you to find the absolute value of the colour/scalar/vector coming into the Input. The absolute value of a number is its value regardless of whether it is positive or negative. In practice, this means the absolute value is always a positive number. For example:

 

The absolute value of 4 is 4

The absolute value -2 is 2

The absolute value of 0 is 0

 

This function works in a component-wise fashion for colours and vectors, so using vectors as an example :

 

( 2.1, -6, 4 ) becomes ( 2.1, 6, 4 )

( -10, -3, -2 ) becomes ( 10, 3, 2 )
