algorithmic modeling for Rhino

Hello;

Is it possible to reverse the image sampler output values so that the black area is given value "1" and the white area is given value "0"?

Hi Zayad,

 

you can use the Remap Numbers Component (Math/Domain/RemapNumbers)

With this component you can define a new Range for a List of Numbers. If you set the Target Domain to

"1 To 0" all Numbers will be in the Range.

 

 

hope this helps

 

best

Christoph


Thank you Christoph and David. Now I have two ways to do it!.

Use a subtraction component that does:

 

1 - t

 

where t is the sampled value. Christophs solution is far more flexible but also a bit harder to understand.
