Houdini: Avoid Geometry-Intersections in For-Loops (where you copy geometries to points)

Udemy House Tutorial: www.udemy.com/game-asset-crea...
Thinking Procedural Discord: discordapp.com/invite/b8U5Hdy
I show how to avoid intersectiong geometries when placing them procedural on e.g. walls in a for-loop. In case of an intersection, the newest geometry will not be placed (since it was intersecting with the already existing one).

[@xpisode]

Thanks man! This intersect-checking-for-each-nodes-setup is really beautifully done. Can stop crying with tears of joy.

[@putteneersjoris]

for anyone interested, a very similar result can be achieved by a boolean sop with mode set to 'detect' , expand the detection group to 'flood fill connected geometry' and blast this group. no need for a loop.

[@arixu3752]

Didn't expect I could get further understanding on loop here. Thanks bro.

[@marcelgatabaki5433]

Your Tutorials are always simple yet so powerful. Thank you so much.

[@Tyler-zb6ec]

Wow was this a perfect tutorial. Thank you!

[@muhammetmertturan]

Allah razı olsun aşqom, diğer tutoriallarda asla bulamadım şu "intersection" meselesini... (kızılay)

[@user-pk9bw6ho8m]

this is exactly what I need now))) Thank you)

[@geleopagot]

Thanks! I am right on that tutorial. Very helpful

[@greog1108]

Thank you! Very awesome tutorial.

[@OnkAnCa64]

Thanks for this, clearly explained :)

[@martinkindl83]

nice and simple way, thank you for sharing

[@FaddyVFX]

Simple and easy to understand

[@massimobaita7178]

Thank You very much, Simon!

[@simonfarussell]

Lovely stuff. Thanks

[@ChristopherSprance]

Fantastic video! Helped me solve the issue I was having.
A little tip with Intersection analysis: The more polygons you have the longer the operation will take. So if possible it makes sense to break the parts you're testing into smaller chunks so you're not loading all 900 pieces of your object and running intersect analysis. That will cause it to be incrementally slower each loop iteration.

[@kevinhall7857]

I tried the compile block...but no luck. This tip help a ton, thanks man.

[@sadeghsaem]

that was incredible tips

[@Josh_Foster]

helpful video. thanks!!

[@elk_h]

brilliant. thank you!

[@SergeyPripachkin]

thank you so much... ive been trying to achieve that kind of stuff using vex and its not been fun haha

[@seokinchung]

you are incredible

[@cadudatoro4998]

Amazing! Thx!

[@rattlesnake3d]

awesome man! thank you

[@ThiagoLaranjeiraZerooneBit]

amazing thx bro

[@sub_tropic]

Thank you.

[@coffeeandcgi]

great tut! really helpfull, just a quick question.
is there a relatively simple way to
force the loop to stop from evaluating after
the first couple of frames?

[@varadhiaditya1431]

thanks man

[@OscarGaya]

Very useful tip. But is yet a bit confusing for me the flow of the second block begins. Many Thanks.

[@StephaneSOUBIRAN]

Thx !!!

[@NodeNest]

thanks

[@karlaws5562]

Simon I love these little Houdini videos you've been making. But I'm curious as to why you don't link to this channel on your website, twitter, or main channel?

[@HoudiniSimon]

Hi :) I have several little youtube channels where i post a video when i learned something new but all of those have nothing to do with each other. That's why I didn't link them together anywhere. But you're right, maybe I could mention them on my blog for people who might potentially interested...thanks for your comment! :)

[@boole_cat]

super!

[@JoseCastro-sm9by]

@HoudiniSimon
Wow, it really works! you saved my day!!
Although I have a question.
Suppose I feed the graph of the for each with points that belong to 3 different groups. How could I do so that the points belonging to the same group do not eliminate each other?
Thank you

[@user-sl309jd90]

Can you add compile blocks this way too? I'm getting an error and not sure how to implement it

[@supaflykai]

Is there any way to get this to work with an instancer?

[@juancarlosgzrz]

It doesn't work with scattered objects

[@aufgespielt3768]

Hey Simon! Vielen Dank für deine genialen Tutorials. Ich nehme jetzt einfach mal an das Du ebenfalls Deutscher bist und frage Dich einfach mal direkt 😅 Nach einigen Wochen der Einarbeitung in Houdini und dem leider bescheidenen Foren Feedback von SideFX, wärst Du wohl einer der letzten, welcher mir sicherlich als einziger noch bei meinem Problem eines Projekts helfen könnte. Besitzt Du zufällig einen Discord oder anderen Kommunikationswege um Dich direkter kontaktieren zu können? Besten Dank und liebe Grüße. Boris

[@HoudiniSimon]

Hi Boris,
klar, kein Problem. Ich bin dir gerade über Twitter gefolgt (gamedevpodcast) und dort kannst du gern eine DM schreiben. Ich bin aber schon wieder ein bisschenraus aus Houdini und ich denke der "Thinking Procedural" discord bietet sicher mehr Hilfe. Oder auch unser GameDevPodcast discord wo es auch ein paar Tech Artists gibt.
