Jon Cheese

Yesterday I was chatting with Jon (user: Hetzen) and often when he's trying to explain me blue node/math concepts I have no clue what he is saying

In Dutch we have a saying for this which literally translates to: I can't make cheese of it.

However, this time he demonstrated me how to make a cube shaped cloud and miraculously I did understand it and "could make cheese of it"....which I did

Cheers Jon,
Martin

Wow, that's crazy! Although to me it looks more like a sponge than cheese.
So how can you create a cube shaped cloud and how did you get the holes inside? Can you create clouds of any shape?

Hi Hannes,

Yeah a sponge...I can see that too

The cube is simple to understand, but I would never be able to make it up myself from scratch.
Like being able to understand a different language, but unable to speak it.

I'll ask if he's fine with sharing it here...

Cheers,
Martin

Thanks a lot, Martin.
Although I'm afraid I know how that is going to end. Jon is sharing his secrets and I won't understand anything.

Ghehe well I think it's not that much of a big secret on how to make a cloud cube...it isn't that useful other than teaching purposes

And...if I can understand then you definitely can Hannes. Trust me!

Very nice, Martin. I'd say, mask a cloud by some height and SSS restrictions, then a huge concentration and deduct a perlin 3D from it.

Funny one. Nice playing.

Thanks Ulco, kudos to Jon though

No no no no...no SSS...that's no math/blue nodes

But of course you're right, it would probably be much simpler to do it that way.
Indeed, I used a high density and high edge sharpness cloud and subtracted a dotted noise from it. Not Perlin3D actually, but a tweaked Voronoi 3D A vector.

Jon Cheese!!!! Thanks.

Sure post the tgc, it was my effort in trying to explain what is happening in the math when a ray is cast at render time.

Nice adaptation btw.

I didn't know you didn't like John Cleese

I know, very bad pun

Hannes, here it is...

Not that difficult once you have seen it, isn't it?

Where have you been back then?

Just one of some old threads on that.

Very cool sponge-sheese. I like it

Hannes · October 24, 2014, 03:58:31 AM

Right, not that difficult once I've seen it....

But what are all those blue rectangles for?

Thanks a lot, but I'm afraid I was right. I have no idea how this works. Never underestimate my dumbness

I never liked conditionals.

Create High and Low pass filters by using hard step scalars. connecting the axis to one of the input tabs,
and a constant to the other.
