How to get the x component of a point?

Gerwang · January 11, 2016, 06:53

Hello Foamers!

I'm trying to modify decompose method, for which I need to get the x component of a point.

A series of points is defined like this:

Code:

pointField points

There is a way to get the value of its X component and it works like this:

Code:

points.component(vector::X)

What this returns is a vector(I think), but how can I get the certain component of this vector? e.g. the first component of it.
I tried points.component(vector::X)[0], points.component(vector::X).value(0), points.component(vector::X).component(0). But none of them works.

Does anyone has an idea? I'd be very appreciate for your answer!

Best regards

I figured out one way to do it, and now it works, just use:

Code:

points[0].component(vector::X)
