Hello everyone,
I am currently trying to recreate the project by Daria Togunova. However, I would like to incorporate different objects that animate according to their size, similar to how Esben Oxholm once demonstrated. How can I integrate the different objects into the dynamic grid and animate them in proportion?

I would greatly appreciate any help and a solution. Thank you very much.

The .hipcl File is attached


Here are the examples:

I don't know any of the people/references mentioned but I did share on Discord years ago, something that looks like it goes along with what you're exploring.

"How can I integrate the different objects into the dynamic grid and animate them in proportion?"

"matchsize" node is your best friend here, turn on scale to fit, turn off uniform scale
which will scale the input geometry to the bounds of the bounding box on the second input.

Basically it's a case of using a loop ect to run over each primitive in the dynamic grid, extrude to make
your bounding box of (whatever height), matchsize a given object to this, repeat....put an attribute on the grid
to be read at each loop iteration controlling which object to place in that grid if any, should be job done!


Cheers!

Dear probiner, thank you for your example.
Is it possible to send the file for more details? That would be great.
Many thanks to you.

Dear EZiniT, thank you for your hint to make it with "matchsize".
I will try it and hope it will go forward.
Thank you very much.

Daria Togunova has a nice tutorial of how to create a dynamic grid on youtube called "Creating a Dynamic Grid Animation in Houdini" I guess you have seen that, if not it's worth a watch.

To expand on the "matchsize" so you can see it in action, attached is an alternative simplified version of a dynamic grid and
how to use the "matchsize" node to fit different objects to each grid location.

This should be more helpful and give a starting point to go forward a bit easier.



Cheers!

Hello EZiniT,
I hope I set the node points correctly, but it works perfect. Your help is great. Attached is the example.
I think that if I fine-tune the settings for red node and green node at the beginning, I could also avoid the collision of the individual objects.

Thank you very much for your help.

Here is my try on it, i tried to replicate the first video you sent here, i liked the way they dynamically squash and try to preserve their previous scale, which i replicated using a solver.

Hello Umang_Raj,

thank you very much for your example of your version to the dynamic grid. It is really very good and an interesting solution. Truly great. This will keep me busy for quite a while. Many thanks for that.

Hello Daniel, looks like you have a plenty of material to work with now.

Attached is a minor update to my previous post improving the processing speed quite considerably by compiling the for loop.


Happy New Year!
