This not only inspired me artistically, but also to pursue a deeper understanding of nature, math, and coding. Thank you for your work.
i haven't felt this much child-like excitement in such a long time. you're a blessing, my man
What an awesome add on! Thank you so much!
This is amazing! Thank you for sharing it with the rest of us.
I so look forward to using this. Many thanks.
Fascinating add on. It's almost therapeutic to watch the shapes grow.
fantastic, I love it. I have been looking for something like this for a while, was thinking to look in geometry nodes but this is really great. thanks so much
Just to echo what's been said already, GREAT JOB with this addon, its AMAZING. There's so much to explore here and apply with this tool you created. THANK YOU is not enough
This is crazy, I'm excited to try this out! I feel like this could be very useful for simulating fungus growth or something similar -- at least, that's what it looks like to me.
Thank you for sharing this amazing addon & taking time to create the tutorial. I agree with all the positive comments below.
Very well done, clear & easy to understand. So beautiful. Very inspiring. I can hardly wait to try it. 👍😉👍
great and detailed tutorial! thanks!
People like you, who bring such amazing things to open source are truly enriching the already beautiful world of open source.
You're breathtaking *with keanu smile*
I tried this addon, and tried on a few different meshes and it produces mesmerizing organic results.
I was just wondering, how to exactly animate the growth.
Very interesting idea! And as it seems it has a lot of potential to become able to produce even more complex shapes. Thanks a lot for offering it.
Thank you for your kind words
fantastic work. I enjoy playing around with different settings! Thanks for sharing!
Thank you, glad you find it useful
This is incredibly cool, amazing work!
Thank you for the kind words
Awesome work!
Only just started trying out this addon and already fascinated by the results it gives. Absolutely brilliant, it's something completely different to the normal addons we see, excellent work!
Thanks so much for the kind and inspiring words
This was helped me a lot! Thank you so much~
It's.....beautiful!
Thanks for sharing it
OMG this is so helpful! The easiest way to create a procedural growth in blender!!
Fantastic, thanks for making this! And to add to the (many) comments on this, animation tools would be a great addition (:
Thank you. Looking forward to experimenting with this.
Awesome, best of luck with your trials!
This is great, thank you!
You have created an amazing tool ! Nice to see add on that provide organic shapes that could be created in houdini :) Thanks a lot ! have a nice day
Great tutorial!
This is so freaking cool.
Thank you.
very useful and informative! - thanks so much for sharing the code
Thank you for the kind words
Phenomenal job. Settings are so easy to understand. It would be cool to get a second button with a multiplier slider which advances the simulation in a set steps at once :) Thank you for sharing this with us!
Thank you
this is on some another level !! thank you for this
Thanks for the kind words, glad you liked it
its insane how versatile Blender is ... knew it was the right tool when I first installed it
comunity makes just the best features
Thank you for the kind words
It's beautiful. Thank you so much for sharing.
Thank you! Cheers!
Really Cool!
Thanks so much!
great job!!!!!
Hey men, i say Amen to your work(and to your 3D printing trials aswell). Thank you so much for bringing your research for free over Blender. It feels like you found an elegant way to create organic looking designs without the need of grasshopper for parametric modeling. You are opening a fresh new way of using blender . It's so nice :3 Bravo !
Aw thanks for such kind words
@@alphamagenta8478 Awesome tutorial! I can't seem to view your 3Dprints on your blog but would love to see them if you have posted them in anywhere else??
thank you Sir!!
So cool! thanks
So cool, just damn i will try it
love It, thank you for sharing!
Thanks for the kind words
Thank you so much!!
yep, this is my fave addon of all time
Thank you
This looks amazing .. really interesting :)
Thanks so much
This is magic !
dope. thanks!
This is genius, thank you!
Thanks, glad you like it!
Thank you
This is insane. It's simply awesome.
Thanks a ton!
@@alphamagenta8478 Man, thank you.
Very cool. I love how much math mimics nature!
mathematics further shows us the beauty with which our creator has created this universe
I couldn't agree more
@@alphamagenta8478 thanks for such amazing video
math is nature
thanks for share
Thanks!
genius! thank you!
Thanks, glad you like it
thx a lot
Cool, i can finally make a model of my aquarium
Very Cool. Hope it remains a free addon!
Thank you! Definitely will be ∞ free
LOVE
Thank you i love u
This is exactly what blender needs! Thank you so much!
Thank you
Nice one. Is there attributes to define start and end points to use material split?
Love this Add-on!!! Will there be any future developments with it? So much potential!! Thanks :)
💜
This is beautiful. Awesome work.
By any chance, are there any updates on the horizon for compatibility with newer versions of Blender, too..?
I hope this is someday ported to geo nodes, would be great for animating it.
extreme cool addon!!!
but how can i avoid self intersections in the blue parts? it seems that there is no collision.
Is this animatable?
*꧁ Прям 👍 Благодарю 👌 ꧂*
Wow! This is awesome! Can you animate the growth steps?
Thank you
@@alphamagenta8478 Its possible to keyframe every parameter, maybe it just needs a script that hits the Diff Growth Step button after each rendered frame.
It's amazing！But I'm confused how to turn it into an animation.
Very nice work - can we use on a line with the top vertex defined as a group?
Thank you! Interesting question; I don't think it would due to how weights are re-distributed after each subdivision step, but it might be worth a try.
At the start you can make that much faster by selecting all vert --> F --> poke face
amazing! is it possibile to do animation with it?
hay thanks a lot! how do you animate it?
how to add the cool textures?
Is there a way to make this growth animated???
Hi,
So already great job, I'm impressed!
We still can't animate this?
Extremely cool. Love this. Is there any way to store the individual states so it can become an animated model? Perhaps by incrementing click per frame and writing to alembic?
Thank you
@@alphamagenta8478 Hey, if you do figure it out, I'd be happy to pay you for an addon.
Might not be the best option but you could always render a frame then increment the simulation then render and so on. Very slow but would work
@@owenmaynard8529 I think it might be more efficient to make a Run state > Export alembic frame. Then loop it. Reimport it as an alembic sequence. Run for 500 clicks or so. Now I wanna learn python just so I can script it, hah. Tedious but can't go wrong.
Rendering per frame is an extra step from what I can imagine.
Hey, thanks for the suggestion - I was hoping to look at exporting the frames to Alembic files some time soon (sorry I can't promise anything specific b/c I'm quite affected by the real world situation at hand)
would love to be able to animate this
How do I animated from the start to the end growing
I wish I knew too, this procedure isn't much good to me unless I can animate growth
how can I undo the steps fastly as he did?
I could make some really interesting visuals with this.
I'm trying to replicate that with Vellum in Houdini, but I'm pretty far from your results. Really awesome
hey! how do animate growth step?
i am just curious because i am new at blender
is addon for blender make by user self?? how to make our own addon,something like this? what should i learn to able making addon similiar like this
Hey, of course all the software is written by humans :)
Generally to create an addon you'd need to learn some Python and at very least go through a Blender Addon tutorial docs.blender.org/manual/en/latest/advanced/scripting/addon_tutorial.html - but that's just a beginning. In order to create something useful with geometry you'll need some basic geometry, vector math, as well as some basic knowledge about meshes are and how to use Blender APIs (i.e. BMesh, k-d tree, etc) to access and manipulate them.
None of these is particularly hard or tricky, but I wouldn't say this is for everyone - in fact I don't think many of the Blender users (myself included) would ever touch Python unless it's absolutely necessary. Instead I'd try to stick with other procedural techniques like modifiers and/or Geometry nodes.
Hope that helps :)
@@alphamagenta8478 wow thats sound really hard to learn
I've been waiting for something like this ever since I learned about differential growth! Does it work on solid shapes?
The next most obvious improvement would be to have a button that can run N steps so you don't have to click the step button like a maniac.
Beyond that it would be great if you could then create sort of animation curves that would gradually change the parameters over time so that you could run a bunch of steps with smoothly changing parameters.
Thanks, great feedback
@@alphamagenta8478 Hmm. Or how about just a play/pause button. Also maybe an undo checkpoint could just be set when you press the button, but at every step.
@@alphamagenta8478great great job! I can hardly wait to try it after work!
For the generator steps what about a button line which would look like something like this:
(-10) (-5) (-1) (+1) (+5) (+10)
@@alphamagenta8478 The decay effect of holding cmd+z is so beautiful--I would love to be able to animate the growth in Blender.
How can i use this addon? I dont see for what i can use it
Amazing! how can I animate this?
Thanks! To be frank I didn't really created this one with animation in mind, since I was going for complex procedurally generated geometry for 3D printing. But since many people out there are interested in animation, I'm looking into it. So far my best bet is Alembic, which is a bit cumbersome, but likely achievable.
@@alphamagenta8478 that’s great news for blender noobs like me :) would be so dope to do a lil animation with this.
somehow installation does not work. it does not appear in the add ons list... :/ But thanks for showing this cool feature.
Is it possible to animate this?
is this possible to animate?
pls make more tutorials
Can you animate the growth?
as i understand animation isn't currently available, but if you need you can make a bunch of copies or animate shapekeys
@@Sober-MindedYT thanks this was helpful
@Fim Dol this is correct; I'll try exploring the Alembic option as was suggested by others, but that's pretty much along the same line of thinking, since all I have is new mesh data on each step.
can you make a shading tutorial pls?
Oh, I don't think there's too much to share; for the "cover" image of lichen I just quickly mixed some colours with Pointiness and Tangent components, here's the full shading graph imgur.com/a/Ra8vZlo I didn't spend too much time with realism; instead I needed an image that demonstrates the mesh features and works equally well on both white and dark theme, since I wanted to place it on my website that supports both themes (and that's what actually took some time).
How can I animate this growth?
nobody talks about animation, I don't think it's possible
they all look like different kinds of Corals
Not working for me. I can only click generation button few times - then nothing changes!
If you could somehow do this in geometry nodes man OMG that would be amazing. I Still love the addon though lol
Yeah, I really, really like the geometry nodes. Unfortunately, I don't think it's possible at the moment due to the algorithm being simulation based (i.e. a lot of steps, each depending on the result of previous ones). And even if this was somehow solved, nodes still lack a lot of features exposed via Python APIs, e.g. adaptive subdivision and kd-tree operations. Still hoping nodes will improve to the point when all of this becomes possible!
@@alphamagenta8478 Hi! Now that we can test the new Simulation Nodes, what is your opinion? Thanks!
Kinda interested in making it animatable
f
HOW CAN I ANIMATE IT.
why does it stop growing at some point to me? like the entire circle becomes blue. does anyone know why is that happening?
Growth inhibitors, it may be a factor of scale though as well.
But go to the last values, which should be "Growth Inhibitors, enter zero value for the base factor, that should allow you to click more growth and have it not inhibit the growth.
The plugin is cool ..but not updated for quite a while:
Animation, nope, you may have to look at geometry nodes for that, there are some differential stuff for that.
There should be reset state button for the plugin, otherwise it starts with the same settings as you used before the growth if you undo, and there should be a preset button to add and activate when you find any interesting growth setting.
thank you very much
