Geometry Nodes - Make BRILLIANT Fiber Optics

In this geometry nodes tutorial, learn how to design procedural fiber optics in Blender! You'll learn in-depth how to create, distribute, and reshape splines; capture attributes; and use those attributes to build a vibrant shader.
If you enjoy this tutorial, be sure to check these out: ➡️ • Geometry Nodes
Heads up that when Shift-Alt-Left clicking on a node, that requires Node Wrangler to be enabled in your Add-ons settings.
Aaand my apologizes for cropping the top of the video. 🤦‍♂️ I've learned what not to do from now on.

Nice result but I think it's getting to the point where we're going to need either a wide screen monitor or a monitor wall just for the geometry node tree. Some of the node setups i've seen creators make are just unnecessarily voluminous in size, but what would I know, I'm just a structural engineer.

[@TiFiDesign]

Yep, some node graphs can get quite insane. Your comment does give me an idea though to alter my layout to get a little more horizontal real estate. Thanks for your feedback!

[@nigellill3222]

@@TiFiDesign Thanks for the reply. I think creators secretly have a thing where they try to see who can use the most amount of nodes to move the default cube 1 blender unit to the right & shade it green ! I suppose it depends who your audience is beginner or advanced. My job is pretty much the same, explaining wind force to a novice you say the structure needs bracing, explaining it to my boss requires a white board full of math. Cheers, have a good day 👍🏼🦘

Thankyou nice tut, would like to see more geo nodes and simulations vid.

[@TiFiDesign]

Thank you! Stay tuned! More on the way.

Hello! Great tutorials, I've a question, where did you learn Geometry nodes? I mean I've seem plenty of tutorials but people seems to know what node is fore before using it, or where to put it, it has been complex for me, I don't only want to know to follow a tutorial but experiment or do whatever comes to my mind but at this moment I'm lost, it's there any kind of resources I need to read or search to know? Or maybe that's something an engineer or a programmer just knows? Thank you.

Hi @Juscuro! Thanks for your comment. Honestly, I’m continually learning geometry nodes! There’s lots to learn and Blender will continually have more and more nodes and features in the future, so we’ll all be learning geometry nodes for a while. And although the concepts of geometry nodes may come a little more intuitively to engineers or programmers, anyone can learn it through study and practice. My best advice would be 1) acknowledge that you *can* learn it, and 2) patiently study and experiment and practice. I experiment all the time to better understand how it all works. And if I don’t get it right then that misstep (I don’t want to call it failure) still helps me to learn and improve. If you haven’t yet, subscribe to join the channel! This is really a place for us to learn together. Over time, you’ll feel more comfortable with your ability to use geometry nodes. You got this!

[@nicolanarracci]

please use a resolution scale bigger or a smaller monitor , is very difficult to see the node

[@TiFiDesign]

Sorry about that. Thanks for the feedback. I’ll keep this in mind. My next video I’ve recorded I did increase the UI scale so I hope it helps.

[@TiFiDesign]

In my latest video I bumped the scale a bit. I hope this helps. Let me know what you think: kzbin.info/www/bejne/gZizga2Hq9OHhbc
