I feel like I came back to this video every month. Every time I am having a problem in geometry nodes I watch this video and find a solution. Thank you so much!

[Xaqaria]

I've been looking for this specific type of reference for some time. Most tutorials only show how the math or node works, not practical examples. Saved for later reference! Great job.

[cherico]

this is great for anyone who wants to mess around in geometry nodes and helps to visualize what the math nodes are doing. Especially when you follow tutorials so you know what is really happening behind the scenes

[condopony]

You really succeeded in simplifying things to really make things click and I keep coming back to this video whenever I'm trying to figure something out. Thank you so much for making this!

That Mario/Boo dot product explanation at 17:24 was just perfect! Thank you!

[christiansanchez]

This is probably the single most helpful video I have ever watched on youtube

[nathitappan]

This video is awesome! Thanks for dummyin down for my math adverse brain!

But even more awesome? Your UV Unwrapped walls and real life cgcookie courses trinkets in the back. Love them!

[Keilnoth]

This is so well explained. I can finally understand what I am looking at in Shader Nodes and Geometry Nodes. I was researching on how to do a parallax effect in shader nodes and they were using all these vector math with incoming ray but I couldn't wrap my head around it. Now I can... try, at least...

[moharmon]

Wow really great explanation. I think of myself as someone who generally 'gets math' and I still learned a ton from this video. Great explanations and I love the fun examples with Mario/Boo etc.

[velvetfeather]

Was looking for this exact information over the past two days. You've made my blender journey so much easier once again. Thanks a lot! Fantastic explanations!

[CravenLovelace]

Must say this was exceptionally useful. Helped me understand things I have struggled with for a long time. Thank you!

[slovakthrowback]

This is actually really cool and well made, thanks for doing this!

[HARDstoned]

Super cool vid! Please do more similar ones. Technical things in the simple words🔥

[TiFiDesign]

This was such a valuable lesson! I'll never forget "aCross Product", being perpendicular/across to the plane created by the other two vectors. Amazing video! As a challenge I recreated the custom Mesh Arrow node group and am playing with the concepts now. Thanks for your hard work to teach this!

[activemotionpictures]

One video to rule them all. Thank you. Masterclass for vectors.

[voyageruk]

Great job, I will need to keep watching this over until it really starts to sink in

[freeThinker]

really great material. Having worked with teaching vector math at university level, I think you are really on to something here. Well done.

[JoacimSvedlund]

Yes yes yes! Exactly the kind of resoource I've been looking for, for quite some time. I'd really enjoy a continuation introducing intermediate concepts and examples. Thank you!

[beinaidoPichaido]

Great explanation, make all easier to understand. Thanks!

[DavidGillemo]

Oh the POWER of visual arrows!! Thank you so much for this!
