Interesting lesson, thanks. Perhaps you know how to use geometric nodes at one point on a curve to change the profile of an object moving along a curve. For example, this is a ribbon that hangs in a ring and, at the bend, bends slightly in a semicircle perpendicular to the curve. Thank you.
please can you make tutorail about how to make animation of light like you show in beginning video ? , like make light Trace the path of a specific shape, whether it is a two-dimensional circle or the sides of a three-dimensional cube
If you refer to the radar animation, I didn't create it myself, it's a stock video I used. However, I think it's a great idea to show how to do like a scanner radar. I will think about it for a future tutorial :)
In my (American English) head I have renamed 'Sample Index' to 'Get Value At Index'. The word 'sample' always suggests statistics to me even though I know this node has nothing to do with statistical sampling. In this excellent example: GET the position vector at INDEX 66 of the vertex domain in a grid mesh and use it to SET the POSITION an entire UV SPHERE mesh.
simple technique, it's a bit tricky when you have complex geometry to find the index. it also doesn't really work when you have dynamic geometry (example: I want to use the last vector in a shape that changes). maybe there's another more suited technique for procedural workflow... edit: you can use 'domain size' to dynamically get the last index of a mesh 🤘 (make sure to -1 before using it though)
Warning: Geo Node Devs change how node do indexing *every* version. So, from one version to the next, "sample index" will yield different results, depending on the node.
I will use "Store Named Attribute" to save this data and then in the next GN setup I will use it with "Named Attribute". These 2 nodes are to store info (attributes) and use it later :)
Yes you can. You have to sample index after Distribute Points on Faces. Look at this picture where I can send the sphere in any point position I want :) freeimage.host/i/2TIkT5g

You have a talent for explaining. Very clear and meaningful. thank you for your videos.
Thank you, I appreciate it 😊
Absolutely brilliant I wish all blender node explanations with this good, thank you
You are very good teacher. Thank you.
wow you explain so easy to understand, +1 sub and i hope can learn more nodes in blender
Superb lecture ❤
THANKS
love your vid
very good explanation!
Great tutorial as usual. Much appreciated.

Here you have the tutorial to create a radar animation 😎 ruclips.net/video/DsJOS95nnfg/видео.html
Wonderful!
Geometry nodes are looking cool and interesting❤
Thank you.
Excellent explanation
Haha Ryan Gosling asking why happens every time i use a sample index value now. Thank you man!
I love that meme 😂

Very useful! Is it possible to very simply show the index numbers for the faces or edges using this method?
With Viewer Node you can show the index of any element. Check this tutorial to see more examples 😉 ruclips.net/video/wlFgf2nPJWo/видео.html
@@Xan3Dcompletely missed that, thank you!

Easy to understand ! :D
Very clear Tx;)
May I ask how do I transfer this position to another geo node setup on another object so I can process it there further?
I will use "Store Named Attribute" to save this data and then in the next GN setup I will use it with "Named Attribute". These 2 nodes are to store info (attributes) and use it later :)
Ok, but how you can make it when you want to know position of point in "Distribute points on Faces" Node? Thats dont work with it.
Yes you can. You have to sample index after Distribute Points on Faces. Look at this picture where I can send the sphere in any point position I want :) freeimage.host/i/2TIkT5g
