Love it! I'm gonna use this in my next video. Spent the last 90 minutes trying to get my DNA to unfurl with proximity but it doesn't look natural. Looking forward to seeing how you accomplished it like in your reddit post.
Excited to see what you make with it! I actually ended up using some nodes from 3.1 to get the unwinding to work correctly, so that's maybe why you were having some trouble. Details to come soon!
There's an issue with the rung orientations in these tutorials: the rung on one side should match the angle of the rung on the other side forming a single bar, but if you look down the middle here the rungs all meet at an angle. This is a result of the 2 helices not being evenly offset (the DNA off-kilter look.) I was able to fix it by adding a Vector Math node to the each of the rotation outputs coming out of the Helix Group Nodes: one side's X axis rotates slightly negative, the other the same amount but positive. This corrected the rung's orientation so they always match, but I personally had to eyeball the values. I'm sure the correction amount is some combination of the period and the offset, but I couldn't figure out the math driving it.
Hi Estefez, Would you happen to know a good reference for this information about DNA? Is there a resource you would recommend that provides information about DNA structure for modeling?
Hi Brady, Thank you for this wonderful tutorial! Would you also be able to capture the normal attribute before you apply the transformation (based on the normal; in-between the set curve tilt and set position node) and plug that into the align euler to vector node? Additionally, the transformation seems to mess with the normals: is there any way to revert that or further investigate what is going on?
this is not working for me, i have the very same node setup but the cylinders are not aligning as expected to the substraction between the helix position and the bezier curve position. Strangely the capture attribute has the point and vector dropdowns inverted... but i doubt it has to do with that
Thanks for this - my first introduction to geometry nodes! But I cannot select point in the capture attribute node? Clearly a new implementation in latest Blender. Any suggestions?
Thanks! I show that in one of my later videos here: DNA in Molecular Nodes | Blender for Biochemists | Geometry Nodes ruclips.net/video/Slk0e_cRmlk/видео.html
Your work is very impressive Brady. The DNA that you show is man made. The real DNA is produced by Nature. I show that DNA from nature is produced by the Atomic slope angles of the Icosa and that of the Cube. The rung slope angle of the 3 Types of DNA match up to the Slope n Rise Vector Angles of the Icosahedron and these Phi Vectors give us the Sine Waves also. Each rung comes from 3D Platonic Order of Slope Angles and Quad Step Rings that match the 3D Geometry of molecules in each Base Pair. All this comes from a very accurate 3D Atomic Structure of the 3D Platonic Phi Vector Order and it does not come from Chaos Theory or by the creation of a good 3D artist by the name of Brady. Your 3D skills will one day give us the answer to the 3D Geometry of a deadly Virus. It will not be found by the 2 dimensional Big Fish who have been feeding us Chaos Theory Baloney. Please continue your good work. You need to focus on the accurate 3D molecular structure of life forms and it will bring you in a hell of a lot more than a cup of coffee.
Thank you so much!
very useful , thank you for sharing your work, I hope you will update more Blender videos in the future.
Great insight into an actual use of gn outside of my games / entertainment bubble! Thank you!
Thanks mate! Hopefully lots more to come
Great tutorial, thank you so much! Can’t wait to see how to do base pairing
Thank you! On it's way :)
I managed! Love it! Thanks for the very clear instructions.

@@BradyJohnston thank you! Can’t wait to see what you do next!
Nice to see another tutorial, pretty interesting using geometry nodes, not something i've played with.
Should definitely give them more of a try, you can do a lot with geometry nodes!
Thanks for that great tutorial! I'm definitely hooked on geometry notes and that was the perfect project to start. Looking forward to part 2 ☺️
The more you get into GN, the more you realise that you can do. Excited to see what you can do with these new found powers :)
This was amazing! Thanks a lot for your effort in making these tutorials!
Thanks mate! More on the way :)
@@BradyJohnston Just a curiosity, how long did it take to come up with the geometry tree of this first part?
Awesome tutorial! Great help

So how do you get the "transparency" mode @11:19 ?
This is X-ray mode, you can activate using "Shift + Z" to get in and out of it.
Thanks for this! Keep up the good job
Thanks, will do!
Nice sir. More than vedos for biology
this is not working for me, i have the very same node setup but the cylinders are not aligning as expected to the substraction between the helix position and the bezier curve position. Strangely the capture attribute has the point and vector dropdowns inverted... but i doubt it has to do with that

The capture attribute node should still be part of GN - which part are you talking about?
Great tutorials! Thank you for sharing your expertise! How did you create the DNA that wraps around the histones?
