Transformers Cubes

Hi

How can i do this animation effect with houdini ( done with TP) :

Thanks

[kleer001]

What part are you stuck on? Where to start? The moving logic?

 

How detailed do you need?

 

What's it for?

 

What you end up with should depend on what you need. Right?

Hi

Im looking for how to do a loop that evaluate everytime to nearest position and going to it.

But if your using cubes like that you will get two or four or six closest positions each time you evaluate...

 

But to answer your question you should probably use a python node in a sop that will evaluate at each frame(you may need a solver sop to make it do that not sure), that way you can implement decision making ability for your cubes.

I think it will be easier to have points manipulated first and then cubes copied to them at end.

 

sopsolver can make that propagation easy

You can do all of this inside pointwrangle/vop node inside dop sop solver.

Thanks

Yeah i will copy boxes on the points. But im new user of houdini. And i dont know write a python code. So if someone can give an exemple scene, that will let me understund new things (nodes) in houdini.

Thanks

Apologies for the off topic, but I think this could be a nice challenge idea

Hi eetu

 

yeah , agree with you

start with a 10x10 grid, drop an add & do "remove geo keep points", to the add drop a sop solver. Jump into the sop solver and wire a point wrangle to the previous frame input. inside the point wrangle is a bunch of example code under the down facing triangle pull down (not the presets). With the manual open next to you you should be able to go from there.

[yesyes]

he is new, he will find point wrangle difficult. VOPSOP will be better

I create a demo file for a vhug one that has some setups that might point you in the right direction:

Thanks Koen for the file but seriously ,still cant make a setup to do the effect 

[Shinjipierre]

well, look for the cigarette or match tutorial made by Peter quint, that should give you a nice basis. (using the sopsolver)

as for the way it's behaving, I would look at some labyrinth creation algorythm, you should be able to get nice shapes from it.

Thanks Shinji

 

i watched the video and learn some news things but still cant find the right way to do the effect 

[khalid]

Hi

 

thats what i can really do , its a cool effect but i want to have the animation (cubes moving )that we have in the video reference , some idea ? try something with my hip file if you want. thanks

hello

 

No one can help ?

 

Thanks

[dyei nightmare]

yeah i will make u a file dude

In it's essence this is an exercise in path finding.
So you should search for pathfinding algorithms here or on google - or in the houdini help. I think the pathfinding algorithms are currently in 13 - haven't used them yet though --- you can also find similar info from the 'volume arrival time'.

 

You could also search for growth algorithms. - The growth is restricted by the specific directions.
 

-- All cubes lead back to the one original cube. The one original cube is the root (if you wanted you could have multipled roots/original cubes).

 

Also search for 'unfolding'.

 

 

quick search:

thanks dyei , im waiting for your suggestion.

thanks Pclaes , i will check your links
