Work The Float Curve Node - Blender Geometry Node Basics

[@simplegregg4664]

VERY NICE TUTORIALS, YOU INSPIRE ME MORE TO GO ON WITH MY BLENDER JOURNEY BECAUSE I WAS ABOUT TO GIVE UP. YOU MAKE LEARNING BLENDER VERY EASY & VERY CLEAR. THIS COULD HELP MUCH TO ALL BLENDER BEGINNERS NOT TO GIVE UP BUT STAND UP FOR THE CHALLENGE. GOD BLESS YOU & YOUR FAMILY.

[@JohnnyMatthews]

Thanks for the kind words!

[@juryrigging]

Thank you for answering my question so comprehensively 😀

[@JohnnyMatthews]

You are so welcome!

[@ThadeousM]

Thank you Johnny-san

[@JohnnyMatthews]

You're welcome! I hope it helps :)

[@onjofilms]

I love it.

[@JohnnyMatthews]

I’m glad 🙂

I prefer the colorramp for this kind of operation, but to each his own. Its essentially the same thing in a different visual format.

[@JohnnyMatthews]

Yup absolutely. I like this one for the visual representation in certain situations.

[@btn237]

It’s not the same though, the curve allows you more control over the way easing takes place. There are certain shapes you wouldn’t really be able to create with colorramp

[@patihgenixscoding6914]

coloramp obviously for animation loop

[@deslomator]

I don't know if the float curve (and color ramp) parameters can be accessed from outside the node group, so to expose a 'pointiness' group input I changed the float curve to a couple of switches and greater than nodes. I suppose you could create a proper asset that allows for a variable number of gradient stops (I wouldn't know where to begin).

[@JohnnyMatthews]

I would love it if there was a ramp or curve "input".

[@transcendtient]

It would sure be nice if you can have 1 to 0.

[@neilmarshall5087]

I used the two together. Spline Parameter to control a shape curve, and the Endpoint Selection to control the amount of the thread curve the Spline Parameter and Float Curve affected. I also used the other ends Float Curve to offset on Z the end of the thread curve so that as the thread narrowed the top stayed aligned (well almost) with the rest of the threads angle. Sometimes I do almost feel like I understand GeoNodes... lol

[@JohnnyMatthews]

Nicely done!

[@DanielPartzsch]

It's a pity that that you can't expose the curve to the group.

[@zboy303]

Yeah. Also drop-downs can't be exposed to the group input. Although that would be easier to implement.

[@JohnnyMatthews]

I think that both of these things are on the radar of the developers.

[@JohnnyMatthews]

You could expose that radius input to the node then hook up the curve parameter and curve outside the node.
