Grasshopper

algorithmic modeling for Rhino

Hi,i'm a newly grasshopper and rhino user.

sorry for my basic question.

i wanted to know what is remap numbers is ? and what does is do? and also what are the uses of this component?

i'll appreciate you're responses in advance.

It moves values from one numeric domain to another. Consider you have two numeric domains (10 to 11) and (-100 to 100). Any number you care to imagine is at some percentage along the first domain. For example 10.5 is exactly halfway or at 50%, 12 is at 200%, 5 is at -500%. If you were to remap these values into the other domain, their percentages ought to remain the same, ie.:

10.5 = 50%     becomes   0 (because 0 halfway -100 to 100)

12    = 200%   becomes   300

5      = -500%  becomes  -1100

The most common use of Remap Numbers is to change a set of measurements to be within a given goal domain. For example if you measure brightnesses using the Image Sampler, you get values between 0.0 (black) and 1.0 (white). However these brightnesses are supposed to control rotational angles between 10 and 45 degrees. Thus, you use a Remap component with the source domain (0.0 to 1.0) and the target domain (10 to 45).

Awesome explanation, thank you.

Great explanation 

Thank you....very well explained
