Been watching This Old Tony, Wintergatan and Stuff Made Here a lot in quarantine. And while the idea of having your own home shop and being able to weld is quite romantic, our reality is that neither do we posses the space nor the skills required. But (rejoice!) we have computers and nodes.
In this tutorial Chris Kopic takes you through the steps necessary to procedurally generate welding seams - those little beads of molten metal where two pieces join.

Never seen this quaternion stuff explained so well! thanks! It's really great how you break down the theory before you type the VEX code.

[@NameInsertPlease]

This is THE BEST welding tutorial / resource on the whole internet. THANK YOU!!!!!!

[@Entagma]

Thanks so much! Does that mean Chris is now the better this old Tony?

[@Al1987ac]

So cool! Making a project with metal structures right now, and that's exactly what I need.

[@atanekoatan]

Awesome tutorial, thanks!

[@nicksushkevich]

looks like Boolean node has been changed since, because there are no seams as output geometry parameter, now it's Extract Curves

[@pumpkinscantfly2893]

Thank You very much!

[@andersonbrandaosudario3425]

Thanks for this tutorial! Understanding quaternions is necessary, but what about the "orient along curve" node, connected before copytopoints?

Happy Diwali Entagma. from india

[@vicengsua]

Wouldn't it be easier to just use the tangent as the v@Up vector? That's the way how I have been doing my orient without math together with the normal 😅

[@kanaljarka]

Orientation along curve node comes helpful as well

[@CoolioMartinson]

way to go.

[@seethe639]

Resample has tangent? i was making one manually... *facepalm*

hahaha

@@baldoski hah, welcome to houdini :P

[@baldoski]

@@neilcross5844 I know, I'm just laughing cause it's so natural in Houdini's world :D

[@dimitrishimanovskiy8041]

Why do you use orient which you generate from vectors that you turn into a matrix? Do you get any benefit out of that? Copy to X nodes can just use vectors (N and up) for orientation.

Any idea how you could add a the stick of a stick welder to this and animate it.. with sparks and stuf.. It doesn't look too hard to do.. With the welding sounds...

[@Entagma]

Heyhey,
for adding sparks, this tutorial might serve as an inspiration: th-cam.com/video/igZdpSCNH4c/w-d-xo.html
Cheers, Mo

[@atomboi2028]

Why not just use a MOPs copy to spline, adjust the orientation, and avoid all that VEX?

[@HapaxArt]

This is voodoo!
*grabs a torch*

[@affectreflect]

Nice stuff!!Doesnt the eulertoquaternion vex function create a quaternion from euler angles?

[@abhayrajeev7216]

This channel is pure gold

[@jimjimjim5995]

Cool as always

[@esbenoxholm]

Very neat! I tried this myself a few months back but failed miserably.
Thanks a sharing this great technique.

[@sima_jk]

What a lifesaver. Just what I've been stuck on! Thanks!

[@GHOST_001_Bravo]

Whattttttttttt how did you promoted that parameters on 12:36
By right clicking it's not showing..🤯🤯🤯

Thank You very much, Chris!

[@skynet24x7]

wow...

[@richard_robert]

[@Kmankeg]

I've been struggling with "double cross products" for quaternions etc. This is video is the most helpful video I've seen!! Thanks so much =D
