Essential TD Skills: Designing & Implementing Algorithms

A popular misconception we often encounter when answering questions, is the notion that in order to simulate an effect A that looks somewhat similar to another algorithm we built to simulate effect B, all you need to do is tweak a few parameters.
While true in a few circumstannces, there’s a fundamental difference in tweaking an algorithm’s parameters and designing an algorithm to simulate a specific behaviour.
Even more so, there’s a fundamental difference in designing an algorithm and implementing it.
In this video, Mo goes covers the three (or four) things you’re gonna go through when creating an algorithm and implementing it:
- The Concept
- The Algorithm
- The Implementation
- The Parameter Space (Tweaking Values)

I've never been good at math, almost didn't graduate high school because of it. Things have changed but I still struggle. Mo described Dot Products in a way that finally clicked. As I first watched this, I was going to write a comment saying how helpful this video was. As with all Entagma content it is well produced, thoughtful content, good pace. What better way to say thanks than to send some Patreon support, so that I did. I must say, the education you're dropping is incredible, thanks for making me feel smarter!

[@AadilDar]

Thank you guys for your time!

[@connorscottcook]

Brilliant, thank you for approaching the tutorials from more macro methodology perspective, much appreciated

[@JoeBissell]

this tutorial speak volumes

[@josephknightcom]

High quality. Thank you very much for what you are doing.

[@iAdrian1997]

Awesome! Thanks for the breakdown of your thought process

[@mickyr171]

All these years programming and i could never figure out the dot product, kept getting huge numbers, as soon as you said a normalized vector it clicked perfectly....thankyou so much lol, i now can use it and know how to use it

[@AbirAlamAkash]

you guys doing really great job. its been only 22 days that im working on houidini and learned a lot just by following your tutorials. But i have a request. Would you please do some in depth tutorial on MOPs ?

[@cukpow9031]

its the best tutorial ive seen. thank u so much

[@markoglazersout611]

Great video & explanation ) Thank you

[@jeyko666]

you are my favourite houdini channel by far! quality videos every time

[@timelschner8451]

very good and quite advanced for my head...

[@Renat.K]

Thank you so much!

[@iskander_i2i]

Amazing!! Thanks

[@TheJEFF2mysterio]

love what you do guys, you helped me so much, do u know good ressources to find natural phenomenons that happens in nature so that we can try apply it in houdini? tyyyy

[@user-dd3ph2kw2z]

cool effect !!!

[@McSneakFreaks]

Very great and informative breakdown! I am not very skilled in terms of implementing and figuring out custom algorithms to work with inside houdini for example. But I would like to know how to adjust your algorithm and add objects that are not affected directly by the wind but affect the sand that's moving. For example building in a desert environment stop the sand from moving any further and the sand would start to pile up against the building. I have no idea how to make it that the building is placed in the heightfield and changes the way the sand gets distributed by the wind. Do you have any idea how to approach this?

[@pennryan970]

I am also interested in this

[@legacythegame]

that was wild

[@pennryan970]

How would you program the dunes in Python?

[@bhushankandalkar3104]

after exporting it in c4d cannot see anything. What is going wrong?

[@forton615]

Heightfields is a very specific volume type, try to convert to polygons first.

[@aw_artwebanimation]

Hi, my dunes are just moving in the middle of the area we are creating. I check your files aswell but can not find any difference. Ideas why that id?

[@aw_artwebanimation]

off, I found it you can tweak the distance paramenta. You used 9, whiche was just too small for me.... thanks for the tutorial! Very much enjoy it!

[@a.p.7383]

@@aw_artwebanimation where can i find teh distance parameter?? it's the same for me, i would like to get a smilar result as in the intro but i can't find how i can scale the simulation up like that!

[@domenicologozzo5148]

Any chance you could do a tutorial on this within Blenders new Geometry nodes? That would be awesome

[@Entagma]

As soon as GN is capable of such things, if ever ;-)

[@Lanaur_]

Well, now you could with Simulation Nodes I guess (3.6 alpha)

[@vytasrauckis6703]

Are you executing the entire Houdini steps and commenting in real time? As much as I have learned (which is not much) I cannot see myself being as fast as you are at building these Houdini files.

[@Entagma]

Hey Vytas,
we edit our videos :) We're not good at multitasking, so it's either dropping SOPs or talking. When we try doing both we slow down too.
Cheers, Mo

[@pennryan970]

TD = texture design?

[@Entagma]

TD = Technical Director

[@cslavov]

Being a humble seasoned art director and not a mathemagician, im struck by the simplicity of the actual math involved.
Just a dot product of a normalized vector, dude...and thats it...for what looks like a reasonably complicated sim (at least in my uneducated eyes).
Of course, the problem with having to learn programming in terms of syntax, memorizing functions, libraries, bla-bla-bla - for the artist this is annoying as fk.
Lovely channel.

[@donotpanic5254]

please take video how to render from houdini to cinema 4d
