Voxelizer / Voxel destruction

[broken harbor]

I spent a week on this, and I'm glad I got to work with voxels, there's still stuff to improve and add

no flood fill(

[tidal torrent]

if this becomes an addon will it be possible to specify voxel "resolution"/density?

[astral tree]

@hasty nimbus didn't you work on something similar or am I tripping

[hasty nimbus]

Yeah, it's on the workshop

[dawn talon]

voxel gibs would be epic

[broken harbor]

Its already there, but with some bugs and no physics I cut it for video

[broken harbor]

Honestly, pretty fast

🤔

[tidal torrent]

this must be genuinely crazy with rubat's lightsabers

[hasty nimbus]

Jesus that's impressive

Optimized BFS '3D Flood filling

and now - the parts :P

with phys maybe

[frigid hound]

teardown in gmod

[hasty nimbus]

Do you have a github repo for this? I would love to see how it works internally.

[broken harbor]

Theres no repo yet, I plan to publish one once the addon is ready for release

[broken harbor]

I cant even guess when the addon will be done :D I dont want to release something raw on the wrkshop again

[broken harbor]

"Deformation"

[broken harbor]

CoLLiSiOnSS

[hasty nimbus]

[void veldt]

is that made with physicsInitMultiConvex?

and does it preserve constraints

[broken harbor]

no

Simplex noise

Good thing I was coding voxel terrain, and along the way I ended up making a simplex noise module too :P

[hasty nimbus]

You were working on voxel terrain as well?

How'd that work out?

[broken harbor]

https://www.youtube.com/watch?v=y8V7Qdg1Exg 🤷‍♂️

[hasty nimbus]

Without greedy meshing and with functioning collisions? Damn

[broken harbor]

Im doing all of this for my own learning, to explore voxelss

[hasty nimbus]

That's part of why I'm interested, I've done a lot of poking around with voxels but I've never done anything this involved

idea from meetric video

[pure orbit]

That's awesome

[broken harbor]

corrected

ace of spades

fastfastfast fastfast fast

[thick sail]

Honestly? This is pretty fuckin' cool

[brazen sequoia]

How difficult would it be to darken the voxels near the impact area? That would greatly enhance hit feedback

[broken harbor]

I actually planned this :D Honestly, its not that hard

[astral tree]

we're getting teardown in gmod before gta 6

[broken harbor]

This shit really needs Sparse Voxel Octree binary module

[broken harbor]

optimized collisionssss (and betterrr)

[agile dock]

Has this released? @broken harbor

If not can me and a friend beta test it pls?

[agile dock]

Tysm!

[wind linden]

How do you figure out what color each voxel needs to be and where it is?

do you do some sort of 3d traces on each axis?

[thick sail]

My guess is that it's built based on the model's triangles and their UVs. I'd be curious to hear what the real answer is

[hasty nimbus]

The way I've tackled that problem on my own end is by interpolating uv's and reading from render.ReadPixel on the texture
