aevaI started learning Houdini tonight. And by Houdini, I mean Blender Geometry Nodes :3
I'm hoping to construct an ad-hoc level editor for my driving game thing and export point sets for object placement, curves for the roads, and height maps for elevation. I'm not sure how to make blender shit out a sparse height map, but I'm sure I'll find some abominable way to do it with python.
I wonder if my old wacom tablet still works 🤔
weird, pressure sensitivity doesn't seem to work anymore, but otherwise it seems fine???
ok the gnome wacom settings test panel thing shows the pressure sensitivity working just fine, so I guess it's just the gimp that's the problem hopefully
aaand it crashes blender :|
there's too much linux in here >:(
yup completely random which applications it works with. blender doesn't pick it up at all?
by any chance is this yet another thing wayland fucked up?
I'm gonna have to install Windows again to use this thing aren't I
Yup. It's wayland. again! it's always fucking wayland! I hate you so much wayland. The tablet works fine with Blender if I restart Gnome in Xorg mode. This operating system is such a fucking joke my hands are shaking with anger right now.
If you're going to wander into my mentions to tell me that it's good actually preferred even that the wayland team broke an entire ecosystem of applications that was working just fine for the last 20 years, do me a favor and just go block yourself instead? I'm not in the mood.
when linux gives you wayland you burn linux's house down
I made some progress tonight on learning #GeometryNodes! I made a little relief with an elevation map of Kauaʻi and a blue noise texture to hide the banding.
it's amazing how much blender has changed since i first spent several hours making a shitty gingerbread man in it back in '02
I remarked to someone that the cost of [open source thing] is "you get what you pay for", and was thinking about how that always sounds snarky and mean but it's totally true and it works. I subscribed to "Blender Cloud" years ago for the tutorials and left the ten bucks a month faucet on for all this time and look what all it can do now :O
I like this Zachtronics game
This looks better than expected with an arbitrary height map applied. I don't strictly speaking need to fix the tearing for what I'm doing, but I might try and patch it up later so my in progress screenshots look nicer >_>
my feature wishlist for #blender #geometrynodes
- selective subdivision (either a face selection field input or making the level input a field)
- collapse edges / faces / vertices operator
- python nodes
played around a bit more with my "drawing roads on terrain" prototype today. this is starting to get a little closer to what I want
I revisited the non-uniform grid geometry nodes thing tonight and figured out a terrible hack to stitch the edges. I think I'm starting to get the hang of this.
Side note, I like how all my node graphs end up looking vaguely like deep sea creatures.
I came up with a cool way of generating terrain from a few splines tonight. Might run with this. Just draw some feature lines and boom there's a mountain or a ravine or something.
Here's another one. This took like no time at all to draw out. I feel like I'm on to something.
Celes 🌙@aeva woah this looks so good 
what do you do with the input feature lines to guide the meshing?
@celestia magic :3
@celestia vertex on the grid picks the closest point on a flattened curve and then takes that point's original height
@celestia I've got a bunch of ideas for improvements but the bare bones version is pretty powerful
@aeva nice! 
I like magic I can actually understand for a change :3
so when you say the curve, I assume you somehow interpolate between the splines to make a curved surface?
@aeva oh, or do you actually look for the closest point in any line without interpolation?
I love the low poly look this creates, not sure if intentional or just low res artifact but I'd definitely keep it
@celestia no interpolation, at least not yet. here's what happens when there's only one curve, and when I add a second one
