Join Chris Reilly for an in-depth discussion in this video Understanding sequences, part of Learning Grasshopper.
…Okay, let's get ourselves in order and talk about sequences.…Sequence components, which are found under Sets > Sequence in the component panel,…are used for generating a lists of numbers.…Let's start by looking at the range component.…So range divides a domain into a number of equal sections.…The range component take two inputs.…The first is a domain.…This gives us the high and the low value between which to operate.…The second is a number of steps.…So this is a number of divisions to make over the domain.…
So in this example our domain is from 0 to 20.…So those are our lower and upper limits respectively.…And our number of steps is 10.…So we'll be generating ten numbers evenly spaced between 0 and 20.…And we can figure out the space between those numbers, it's also called…the step size, by dividing the length of the domain, by the number of steps.…So in our example, 20 over 10 equals 2.…And sure enough I can see in my panel here where I…am sending the output from my range component.…
I have these values that are spaced two units apart from each other.…
