Meshroom: 3D models from photos using free photogrammetry software

Meshroom can be downloaded from the AliceVision website here:
alicevision.org/
And it has a great manual (including a beginners tutorial) here:
meshroom-manual.readthedocs.io/en/latest/tutorials…
Information on “Draft Meshing” – which allows Meshroom to be used without an NVIDIA GPU, is here:
github.com/alicevision/meshroom/wiki/Draft-Meshing
Meshmixer can be downloaded from:
www.meshmixer.com/
My previous video in which used AutoDesk 123D Catch to turn the wooden elephant into a 3D model is here: • Explaining 3D Scanning – However, note that this is now an historical curiosity, as 123D Catch required a connection to cloud resources. So even if you could obtain a copy of the program, it would no longer work. Today, Meshroom really is the way to go.

Im glad the elephant in the meshroom was finally addressed.

The plethora of professional tools that are free on the web is insane. You just have to have a guide to advice you and to point out some of them, and you can easily make a living creating stuff, without breaking any law and without having to pay a cent if you don't want to, or can't afford to do so. Thanks for the knowledge you share Chris.

That was one of the most incredible explanations of creating a 3D model I have ever seen. You succinctly explained and articulately demonstrated the entire process from taking the photographs, importing photos, generating the model, to finally producing a final printed object. I love the lion example best and how the final object was printed and made golden. Hard to believe you created that object simply from a series of photographs. Wow. Many thanks!

"Lets go and take a closer look". My favourite words to hear every Sunday.
-
I'm surprised how well it handled specular highlights. These used to be the bane of any photogrammetry project. I've found a good overcast day helped in these situations. Great video .
-
Fascinating software. The final scene where you are standing in front of the statue and holding the printed version was nicely done.
-
That was incredible!! The end result was extremely impressive! And as the software matures, and computer hardware becomes more and more powerful, this process will only get easier.
-
Fascinating. Reminds me of my old university master thesis, which was about "Recovering 3D shapes from perspective projections" (i.e. photographs); I dealt with only two at a time, the corresponding points were marked with a tablet, the implementation was on an HP 2647A intelligent terminal running Basic - I had to do all the necessary Linear Algebra subroutines myself... It was 1980-1981 after all...
-
Another great episode. As a former Army cartographer, and photogrammetry instructor, this absolutely fascinates me. You didn't mention the file sizes of the models, but looking at the spacing of the nodes on the TIN, they must be quite large.
-
Absolutely amazing show off, Chris! I also got into 3D stuff with Blender and it's really fun, bought an RTX 3090 for it and it just spits out rendered PNG images like there's no tomorrow. Scanning real life objects and doing retopology on it is really a learning curve I think.
-
This guy's videos remind me of those TV shows that aired on PBS (or similar channel) in the late 90s early 00s that my parents would watch. I kinda like it.
-
Very impressive what one can achieve with rather low spec hardware and patience... for free! Thanks for showing!
-
Wow! Thanks, as always, for presenting a computer process from start to finish in a clear and concise way.
-
That was quite impressive. You spent an enormous amount of time on this. Thank you.
-
I am imagining Chris roaming the streets of London with a camera looking for statues. This was an an extremely well made video. I cannot imagine the planning that went behind showing a complete end to end project that required not just dealing with new and complex software but activating the neurons responsible for artistic senses. One of the best videos from the channel.
-
Fantastic! Thank you, Chris for another excellent video. You have again presented a complex operation in a manner that the average person can understand and perhaps duplicate.
-
This is remarkable. I'm learning so much from this series. Your first 3D printing video actually inspired me to go out and get a 3D printer after years of being on the fence. I've had a great time and have even designed some replacement parts with Tinkercad and successfully printed them. Looking forward to what else you have in store!
-
Two Minute Papers posted a video about recent strides in AI photogrammetry. Much recommended. What a time to be alive. :)
-
Well it's good to see you finally addressing the elephant in the Meshroom.
-
What an interesting software. Also this is impressive work of art reproduction! I have to share this to a friend who got a 3d printer recently
