3D Gaussian Splatting - Explained!

[@pletch]

I stumbled across this video and I'm blown away. In a former life I use to do a lot of graphics and old-school 3D work. Could I request a beginner's guide on "how to get started" with the tech you covered?

[@alphasiera1757]

This can be used to google maps street view. Imagine instead of clicking arrows to move forward, you just need to press “w” maybe as if you are walking in a video game

[@alvydasjokubauskas2587]

Exactly

[@hallo_ween07]

Maybe too expensive and big for the whole world

[@DirkvanDale]

@@hallo_ween07 Starting with a town maybe? Then slowly moving towards a country? Maybe a different type of google car can be made to use photogrammetry instead

[@ashwinkumar8119]

Hands down the best explainer I’ve found about Gaussian splatting - super clear and understandable without compromising any technical accuracy!

[@creativetechdigest]

Thank you Ashwin!

[@mreflow]

Great breakdown man! I definitely have a better understanding now. :)

[@creativetechdigest]

Is this explanation the one?! 😂

[@laurenneal]

Fantastic! This level of detail is candy for Gaussian Splatting devotees

[@creativetechdigest]

Thanks! I’ve been wondering if I go more high level but I think this might be the way to go

[@BohdanTrotsenko]

I've discovered the topic today and my mind is blown away

[@marekpietrak8279]

Brother your channel is going places. Your content is presented in a very straight forward manner and will get you far. Keep at it. See you at the 1 million Sub mark.

[@MrFaraz1979]

Much needed information, short and crisp, thanks Bilawal

[@OlliHuttunen78]

Very Well explained! Now I really understood the spherical harmonic part of this tech. Thank you.

[@creativetechdigest]

It really is the cherry on top, and love that an OG physics concept helps pull it off!

[@SergioMaciasVazquez]

Incredible Video Ashwin! Thank you - just subscribed!

[@shableep]

this is genuinely the best explanation i've heard on gaussian splatting. especially the part i don't think i've heard anyone talk about that is HUGE, which is *spherical harmonics*. actually showing reflections and the sun through the leaves that you're showing here. massive.

[@bernhardzeisl4437]

Bravo Bilawal! Well done. Straight to the point why GS is such a promising approach. I especially enjoyed the comparison to the "wonky looking broccoli trees" ;-)

[@creativetechdigest]

🥦 🙈 you know all about it 😂 great to see you!

[@JacobNguyen1]

Really great stuff, man -- love the in-depth breakdown done in a conversational manner. Looking forward to seeing your channel's growth!

[@YahiyaJasem]

the editing quality is dope!

[@audunjohansen]

Nice vid bro. I love your editing style

[@mohammadbuhnad9258]

Wow, that's truly impressive! Thank you for this video it explains everything so well Keep up the good work!

[@bmschech]

Thank you, that was clearly explained and very exciting. A very minor quibble is that Gaussian splatting is named for one of the greatest mathematicians of all times. His name is pronounce gawse and the curve he discovered is called the gawsian and is central to the study of probability and statistics. And now, computer graphics!

[@creativetechdigest]

Thank you, and duly noted on pronunciation!

[@sirleto]

i am confused, watching the video right now, and the pronouciation sounds very typical american? i think its good, whats to complain? the real pronouciation of course is difficult for non german speakers, listen here en.wikipedia.org/wiki/File:De-carlfriedrichgauss.ogg

[@daverayment]

​​@@sirletoare you able to say "house" or "mouse"? You don't need to be German to pronounce Gaussian correctly!

[@bmschech]

@@sirleto I don't want to make this a big deal. Mathematicians and physicists all pronounce it this way and thought you might care :) @daverayment explains it better. Gauss rhymes with house.

[@skysurf9]

Really awesome video and how you explained it - clear, crisp, in-depth. And thanks for including links to further resources.

[@DeanCutlet]

If you use enough buzz words and look around the room you can sound like you know what you're talking about. Good job.

[@basedovi]

Amazing tech 💜. Bilawal really makes the inner lost 3d kid in me resurface 🚀

[@RaviKrishnan1984]

Amazing explanation for those working in 3D. Thanks

[@creativetechdigest]

My pleasure!

[@AntonioDePalma71]

The best video on the topic so far and with well represented insights. How would you see Gaussian Splats in the construction industry? Excellent job!

[@creativetechdigest]

Thank you! I think the photogrammetry tools had largely written off Nerf as a fun research toy. Gaussian splatting is making them pay attention and I could see it quickly become a common artifact alongside other reality capture data products in AEC. Amazing for visualization and progress snapshots!

[@AntonioDePalma71]

Would be Interesting to see applications dealing with heritage preservation demands considering we’re typically using Point Clouds. If we could see GS as a resource for model driven Digital Twins and other digital processes for maintenance operations, I think we can cut away hundreds of hours of modelling work.

[@shoaibwaqar9477]

Thanks. Can you make a video of how this can be used for product marketing. Like creating a 3d structure of a product for websites. Can you also confirm if this can be done using some mobile apps

[@creativetechdigest]

@@shoaibwaqar9477it’s a great use case, def possible. For mobile check out Luma AI and Polycam

[@kennethnavarro661]

[@alansmithson5940]

Very clear explanation. Thank you.

[@PopoRamos]

Imagine having a 3D rendering engine that can automatically harness the power of Gaussian splatting for 3D animation, rendering only the needed Ray traced frames to create the splatting and turbo charge the rest of the frames making it possible to render long animations on a single consumer machine in record time.

[@creativetechdigest]

Love this. I think this we’ll get tools like this sooner than we think - 2024 is gonna be a fun one

[@vp-land]

[@punkdigerati]

Gauss-ian, it's named after Carl Friedrich Gauss

[@alexnovikov1609]

Thank you!

[@inxomnyaa]

now i just wish to see some kind of style filters. since it uses point clouds, we definitely have depth as a parameter, giving us stuff like edge highlighting or idk, zoom effects. Could probably train a stylized cartoon filter. Since the splats are mostly gradients, maybe flatten the colors to specific styles? Would be fun to mess with if my PC would be able to process all the stuff :/

[@hectorescobar9450]

I wonder if you can transform a 3D scene with textures into a gaussian splatting format to make games more optimal without sacrificing too much visual quality

[@Ali-wf9ef]

Wow such a good video. I don't need to read the paper anymore

[@creativetechdigest]

Glad you found it helpful!

[@WhatWillCome]

This is awesome. But what if I wanna take the splats to Blender, to insert a 3D statue in the middle of scene? it's possible, or we need some kind of file conversion ?

[@maximilianmander2471]

I think 3d video's will also be a great thing when they are ready? I just have seen a demo of a video that probably had a depth map, so it was a 2d video but made 3d. But when you went behind an object to the side where there was no camera, then there was no object. I think AI could automatically predict what is behind an object and in that way create 3d maps from just normal videos. Then you could watch videos and walk around in those video's. I think this will be amazing.

[@creativetechdigest]

Spot on - I think this is the direction apple seems to be going. Do more sophisticated infilling of a parse 3D capture

[@abowlofrice1245]

Great way of explaining it

[@user-ub1og8ux2s]

Amazing, thank you!

[@bioman1hazard607]

If you put this with garrys mod vr, you've essentially made a working matrix prototype, then it be a matter of what can be scanned.

[@PascalKuraica]

Great Video👍🏼

[@wesside1992]

Will this ever work for video? Could you combined multiple angles of a speaker or actor and create a moving Gaussian splat video? Great video!!

[@VaughnCampbell]

[@ryanbair7624]

Thanks B!

[@paulfedor9828]

I am a VFX artist in Los Angeles who does digital sets, Matte Paintings, and Environments. I am trying to understand Gaussian Splatting from a non white paper stand point. It seems like it takes the capture camera Meta data ...turns it into a point cloud......and when you view it through your camera...it takes the photos or batch of photos that are near by and basically shows you photoprojections from the photo capture? Its basically viewing a flip book of pictures as your moving your camera based on the capture data positions? Forgive my laymen understanding. As a matte painter we do the same thing manually........doing a series of projections based on camera. How far off am I?

[@alannunez3527]

Great video! One pet peeve: it's pronounced gau-see-uhn

[@creativetechdigest]

Thanks! That’s how learned it picking up photoshop as a kid in India lol. Fixed in new video :)

[@brappineau4161]

What is the best gausian splatting software for using drone footage. I have the original DJI MINI so I can't plot routes. I'm assuming video to luma ai would be easiest

[@limegpt]

Interesting

[@Imhotep397]

I’ve been trying to wrap my brain around wth this is for over a year and now I’m thinking it’s basically physics manipulating ova voxels?

[@indibarsarkar3936]

But how do Gaussians show spherical harmonics? Is it a mono colour blob that fades away or does it have many colours showing at different angles?

[@indibarsarkar3936]

class Gaussian: def __init__(self, center, scale, covariance, color): self.center = center self.scale = scale self.covariance = covariance self.color = color #Is this enough? Or is there more to it to attain spherical harmonics?

[@Antagon666]

Wait a minute, so could this in theory greatly speed up ray tracing ? You render just a few points and then interpolate with gaussian splatting.

[@kbssidhuex-ias7959]

Please do a Maven course…😊

[@creativetechdigest]

Potentially. If enough folks are interesting in something dedicated to 3D capture

[@SD_Alias]

I would be interested to see if this improves the quality of splatter movies…

[@sebbes333]

*@Creative Tech Digest* 0:11 No, I have no idea what any of those words means, and several other words, THAT was why I went to this video in the first place, to learn more, but I just get to hear a lot of meaningless words. :(

[@creativetechdigest]

This is good feedback. I have added a “3D Capture 101” video to my queue! This video def assumes you know the basics of photogrammetry and 3d scanning tech

[@pieterboots8566]

Can't this be done with transparent polygons? what is the size of Gaussian splat. About 50 bytes? How do Gaussians splats render faster than polygons?

[@edwinleonelvarela]

How do you use an FPV control to move around? That looks really great

[@creativetechdigest]

The viewer on the 3DGS inria GitHub - also unreal engine itself works for such FPV controls!

[@ibrahimsalisumadaki678]

This is a very interesting and educative video , my question is that what software can you used for the point cloud which software is the best

[@creativetechdigest]

For the initial sparse point cloud / posing of images - colmap is fine but reality capture, Agisoft Metashape, etc would be better. Google also released CamP code this week which is also bette than colmap.

So...how much will it cost me to get into this game? All I've got right now is a reasonably capable PC, a few VR headsets I would like to view this stuff in, and a bit of free time.

[@creativetechdigest]

Not much at all. Use your phone to capture and process in the cloud with luma or polycam. Drop ‘em into Unity and check it out in VR!

[@Gilotopia]

I'm wondering about the spherical harmonics. I really didn't understand how that part works.

[@creativetechdigest]

I suggest watching the linked video as it goes into a lot more detail on how the spherical harmonics are implemented

[@hasoevo]

Great vid, I subscribed. Could you do a vid on dynamic NeRF (DyNeRF)

[@may21136]

Fluid simulation should be faster with Gaussian splatting.

[@puggybooth]

I have a question that almost certainly reveals my total ignorance of this tech! When rendering 3d GS environments in a game engine, is it concievable that game mechanics could be added to this, for instance, pathfinding, collision, decals, all that traditional 3D stuff.

[@creativetechdigest]

it's still early days. you could certainly query metadata you attach to each splat. you could also mix and match - make a mesh version using photogrammetry but keep the visibility off but keep it on for physics collisions, path finding etc.

[@stankleinmentink7186]

Do you know or this also possible with scans made by the matterport pro 3?

[@creativetechdigest]

Maybe. I don’t believe the density of those RGB scans is good enough unless you really put the tripod in a bunch of locations. Though I guess matterport could try to use their depth data in the training process to make up for that sparsity?

[@j0hn7r0n]

I too am wondering how this could be used for capturing 3D models (e.g. as part of a 3D printing workflow)

[@creativetechdigest]

If you want metric accurate continuous surfaces; splatting may not be ideal for your use case. It’s much more suited to “view synthesis tasks”

[@DaveBjornRapp]

Could you render a 3D scene into Gaussian Splats for more rapid playback in game engines? I imagine if you could you could purposefully distribute the points intelligently, creating a better looking final result.

[@creativetechdigest]

Interesting. Reminds me a bit of what Google Seurat was trying to do

[@autonomous2010]

Very cool. How do I photograph a dragon though? Or Aliens?

[@creativetechdigest]

There’s a ton of interesting research that uses radiance fields as the 3D representation but diffusion models for the generation. Quality isn’t quite where MJ is for still imagery tho!

[@klausweismor]

Is it possible to measure inside?

[@creativetechdigest]

Gaussian splatting is good for view synthesis. For real world measurements - you’re better off using classical photogrammetry to densify the point cloud or turn it into mesh and measure that. Of course you need to make sure your scan is metric accurate and to scale. iPhone apps that use the AR metadata eg Polycam do a good job of automating that for you.

[@mihaleben6051]

Its math. It was always math. Except chemistry. Idk how that works. Because if all compounds wanna turn into noble gas, then why is LiN not on pubchem? And why doesnt nitrogen bond with 5 molecules???

[@nobilismaximus]

But, can it model the real physics, or is it a fancy illusion?

[@creativetechdigest]

it's a radiance field so that's a feature not a bug - instead of rasterizing triangles as you would with a triangulated 3D mesh for example - you instead rasterize these gaussian splats. you can still use a mesh under the hood if u want for collisions etc.

It's useless if you can't generate a 3D mesh, something I can take into Blender.

[@creativetechdigest]

There’s a simple plugin for blender but it won’t be a mesh. That would defeat the purpose of creating a radiance field in the first place.

[@MetalGearMk3]

@@creativetechdigest It's more useful as 3d mesh, there is no way to edit and modify radiance fields.
