fart simpson posted:also congrats. youre done! i was supposed to be done right now but i woke up and found out blender crashed halfway through my render. gonna try again while im at work today thanks! yeah it's supposed to be a Dyson sphere. also oof, I know that feeling. you're not rendering straight to a ffmpeg video right?

fart simpson posted:large. added some more stuff. unhappy with the new camera movements but i was going crazy trying to fix a huge problem that was only showing up in final renders and not in viewport (turned out to be too much motion blur) so i didnt spend time fixing the camera. The number of youtube tutorials I would need to watch to get to this point would probably take longer to watch than a certain Japanese pirate cartoon.

you mostly just figure it out via trial and error as you go. i only picked up some very basic stuff from tutorials. the rest is just learning via experimentation a relatively small set of patterns and tricks that you apply over and over again in different ways, and building up an intuition and feel for it also seeing how other people accomplished stuff and reverse engineering it so you understand it too fart simpson fucked around with this message at 02:19 on Nov 30, 2021 |

What version are you using, exactly? I know they changed geo nodes a great deal in the expermental versions.

I was holding off learning geo nodes in full until they finalized the format. I was starting to understand attributes, and then they decided to change it to be more in line with how texture nodes worked, so I decided to wait until things settled down.

the big new thing in 3.0 is "fields" the geometry nodes in 3.0 are sorta evaluated backwards, from group output backward through the tree. this means anything that isn't connected up to the group output isn't evaluated. a "field" is the description of a computation that is evaluated in the context of some geometry. there are some named fields built in, like "position", which is a computation that takes a point and returns its position vector in global space. the position field itself isnt attached to any particular geometry context, so you can plug the exact same position node into multiple different objects in your graph and it will return correct results for each object individually as its evaluated in each context separately. this extends out to calculations you perform on position, so you could plug in "separate xyz" and plug the x into a math add 1 node. now you'd have a new field that returns the x position plus 1 in any geometry context. its kinda like the IO monad in haskell

The way attributes clicked for me is that they're just a name that tell a node which attribute to extract from whatever geometry it manipulates. Another thing that clicked for me with 3.0 geo nodes is that what you plug into diamond shaped inputs are basically functions which are called by whatever node you connect it to to generate data (ie the destination node pulls data from the function as required) I was a bit surprised that the edges aren't just straightforward bundles of data because I thought that's what artists were used to when working with node graphs

Zlodo posted:The way attributes clicked for me is that they're just a name that tell a node which attribute to extract from whatever geometry it manipulates. i dont think theyre just a name, to me theyre more like a computation. the blender devs call this a "named attribute"  and they call this an "anonymous attribute"  and this is a "named attribute" again  im probably a big weirdo here but what made it click for me was thinking about it in haskell terms: both of those examples are kinda like working in the "position monad". the first one is like a simple return expression, the second is like describing a computation within the position monad using an anonymous binding, and the third one is like doing <- binding in do notation but also that 3rd way is very inconvenient to use right now and i've heard talk that they might add back real support for named attributes again the analogy doesnt go that deep if you really think about it but its what made it click for me fart simpson fucked around with this message at 11:28 on Nov 30, 2021 |

Ah that's neat, i didn't realize that you could do computations on the attributes directly before feeding them into something else

how long does it take to recalculate your scene when you update something in a graph like that

Sagebrush posted:how long does it take to recalculate your scene when you update something in a graph like that Looks like it takes a couple seconds https://youtu.be/6RDI7lFbwkU the geometry nodes system is all written in C and its basically just a bunch of matrix operations, the renderer probably usually takes more time than the calculations themselves

yep. my last entry had 2600 nodes and if i switch to solid view instead of rendered view it flies around no problem except mesh boolean nodes take a few seconds in every change, that’s the only slow one

the hardest part of stuff like that is managing your subdivisions and geometry density. you can see when it’s just a diffuse white material the vector displacement is done, the rest is just fancy masking out areas for different mix shader nodes with somewhat basic materials
