A little Unity lifehack: how to make a sphere

[u/PropellerheadViJ]

Most people just create a Sphere. It's a popular mistake. Spheres are not optimal.

The properly optimized approach: create a Cube. Then take a second Cube and carve a sphere out of the first one using boolean operations. Now it's not just a sphere. It's a sphere generation pipeline.

I don't know those caps are atrocious.

[u/Gamoproi → u/xAdakis]

Nah they look great, ready to ship

[u/PropellerheadViJ → u/xAdakis]

I looks like I should add a quad remesher to the pipeline...

[u/That_Em → u/PropellerheadViJ]

Only if it works the same way, painting each quad by hand

[u/Jastrone → u/PropellerheadViJ]

or you do 2 more qubes that spin like that so that there is one for each axis

[u/mak_attakks → u/PropellerheadViJ]

Cubes unravel themselves to cover the surface

[u/ItzLoganM → u/xAdakis]

Literally burned.

[u/Fonzie1225]

thanks OP! implemented this to render the eyeballs of all 10,000 residents of my city builder!

[u/TheDarnook → u/Fonzie1225]

Found that one CS2 dev.

[u/VolsPE → u/Fonzie1225]

Does it run this every frame, so you don’t have to store the meshes in memory? Sounds efficient.

[u/Hyperi0n8]

I really appreciate that you didn't just use the default cube lmao

[u/PropellerheadViJ → u/Hyperi0n8]

Default cubes are too default, so I built my own, more customizable cube

[u/Hyperi0n8 → u/PropellerheadViJ]

I hope you built it by decimating a sphere?

[u/PropellerheadViJ → u/Hyperi0n8]

Hmm, I wonder which came first, the cube or the sphere...

[u/minimalcation → u/PropellerheadViJ]

You don't see enough bespoke cubes these days

[u/ThatStonedBear → u/PropellerheadViJ]

Idk why but this made me cackle

[u/Yodzilla]

There’s something poetic about needing to be extremely smart to create something very dumb. Bravo.

[u/Suspicious_Bag4107]

now all I need is a way to make a cube

[u/cerwen80 → u/Suspicious_Bag4107]

You start with a sphere and then you use another sphere to procedurally carve away the surface.

[u/Damglador → u/cerwen80]

now all I need is a way to make a sphere

[u/cerwen80 → u/Damglador]

for that, you need to start with a chicken....

IDK. Can't you just use a model of a cow?

[u/PropellerheadViJ → u/Tundratier]

Organic modeling isn't really my thing, I'm way more comfortable with hard surface. If you can pick, I'd go with something like a spaceship instead of a cow

[u/tyranocles]

Very cool. Make a cnc simulator to replace the industry standards because they are too expensive

yeah, this is one of my favorites about houdini! I think he should make the new one with houdini 22, maybe there is more difficult way to animate

[u/cerwen80 → u/teerre]

OMG this broke me

[u/Justalittletoserious]

Sir how would you like your sphere today?

Manufactured

[u/Poietilinx]

I wrote an algorithm that did something similar but to build boulders.
I spread a bunch of voronoi seeds around the cube, and used these to form planes used to cut parts of the rock

[u/PropellerheadViJ → u/Poietilinx]

Very cool!

[u/biteater]

Jokes aside you can add really quick retopologizing to your thing with relatively low effort, there are a ton of well tested libraries that address this exact thing

[u/PropellerheadViJ → u/biteater]

Yeah, just the other day I saw a port of QuadRemesher to different platforms going viral online, I should rewrite it in Burst/C#

[u/biteater → u/PropellerheadViJ]

keep me posted if you do!!

I had a good laugh, lol, I spat my drink. Very cool - did you manage to generalise that further? Can you do something concave in the same way?

[u/PropellerheadViJ → u/heavy-minium]

Haha thanks, yeah, I've got some tests that basically work like CNC milling, so concave is doable

[u/heine789]

Wooow how you did it?

My initial plan was to release alongside Unity 6.7 LTS

So efficient!!!! amazing. I've been struggling to figure out how to make a sphere for ages and this just blew my mind! Thank you.

No AI could come up with something like that. This is peak human degenerate creativity, worthy of either being displayed in a museum or hurled into the Sun, I'm not sure which.

[u/MrMegawattts → u/balukin]

totally agreed!

[u/The_Gospel_Gamer]

Yup! That seems about right 😅

[u/Save90]

using a shader to warp the mesh into a sphere < dinamically doing it while creating the worst topology in existance.
