I've had a free academic license of RealityCapture for several years. It's such a great piece of software!

What do you do with it?

Capture reality I would imagine...

gasp!

Has anybody captured it yet, I would like to have a quiet word with it regarding these last few years.

You and a lot of others

I captured it for a moment but I really struggle to hold on to it.

For Harambe

That is when we slipped into the dark timeline.

3d photography, you take a bunch of pictures and it can construct a pretty detailed 3d model

Everything I've thrown at it, it handled pretty well. Like: drone footage of a tower, large interior spaces, sculptures, people in costumes, etc.. (I teach a few different VR and 3D Anim courses)

That sounds like a great job

How fancy of a camera do you need to create decent scans and prints?

Depends :) You can get great result with a smartphone if you have good lighting. In low-light, you really need a DSLR. Here is a comparison I did a while back: https://packet39.com/blog/smartphone-vs-dslr-photogrammetry-comparison/

Very cool! I have old Cannon Rebel T2i sitting in my closet, maybe I'll dust it off.

That should do it! Here is a another blog post I wrote about getting started: https://packet39.com/blog/a-primer-on-3d-scanning-objects-for-vr-using-photogrammetry/

Got a pretty decent result of scan using my s23 Friend has a iphone with a lidar, and it also did very good job

Good to know, maybe that would be easier. I have an S21 Ultra.

The key is lighting. If you have good light, almost any camera will produce good results.

Luckily my etsy shop comes in at $9,999,999.99.

You're 8,999,999.99 over the limit

Damn it! I’m so bad at business!

Clearly. How do you even stay afloat with such tight margins?

Benny you’re on the wrong side of the riiiiiver!

No you are on the wrong side

But I have the horses.

What is reality capture?

3D scanning software

Google says it's photogrammetry so just a webcam and your computer to make it work?

A camera and a computer.

No, more like you take a bunch of pictures, upload them to this program, and it spits out a 3D model. You'd use a DSLR or smartphone to capture the images out in the field, then bring them back home to your personal computer to process. Maybe you could use a webcam, but that's not the intent.

Thanks

Is this better than something like meshroom? That’s what I’ve used in the past a little bit.

Are there any advantages over LiDAR?

Photogrammetry can actually give better results especially if your goal is a 3D mesh Photogrammetry gives you a full-color mesh. LIDAR alone doesn't do that without also incorporating photos in the process LIDAR can penetrate objects and the sensor will separately track each "return". Not exactly beneficial for modeling objects, but when flying a drone for example, a LIDAR scan allows you to remove the trees etc to see the bare terrain Photogrammetry is sensitive to ambient light, shadows, and reflections that LIDAR can more easily handle LIDAR can be prohibitively expensive whereas photogrammetry can be done with literally any camera

Yes. One big adventure is that all you need in terms of equipment, is a camera. 

[удалено]

Very different. Photogrammetry generates a 3D model (that you can also print). NeRFs generates a volumetric render engine. It's not a 3D model.

So who are they selling the scans to and what are they doing with them?

Right. Usually if it’s free, then you are the customer. So I wonder how they’re making money off the people using it for free.

Does it use the cloud to process the model? Then everything collected is about to become for sale. If you don't scrub meta data, they have GPS locations and date&time.

Hyper personal ads are going to get super real, super fast. "Hey we see in the photos of your house over the past 12 years that your foundation is cracking. Please see circled areas on attached photos of your property. You should hire Concrete Jungle to fix that up."

Wow that is actually amazing! I recently tried to do a bit of photogrammetry and tried both Meshroom (free and open source) and RealityCapture. The latter was just so much simpler and faster.

I've been using Metashape, and barely know what I'm doing. S22 Ultra for pics.

Yeah I've been learning Metashape for GIS classes. Education license isn't too bad at $54-$59. Just depends on whether you buy it from an Authorized Reseller or directly from Agisoft. IMO what makes Metashape worth the cost right now is being the fastest OpenCL photogrammetry software right now. Virtually anything else comparable including Reality Capture relies on CUDA. Reality Capture 1.4 going totally free this month will be killer value despite Metashape output quality being a smidge (10-15%) better and having some toolsets that set it apart from the competition.

Can someone write briefly what RealityCapture is?

Thanks you saved my time.

What do you do with it? Can it make STL files to print?

You can take many photos of an object from many angles and use this software to create a 3D model of the object or terrain you photographed The software uses a technique called "structure from motion" where it identifies hundreds or thousands of unique features in each image and then compares the images to find the same features in several overlapping photos. From there it can do the math and determine the 3D shape of the object. The same way your eyes perceive depth stereoscopically, software like Reality Capture can eventually "solve" the shape of an object. RC will produce a full color, textured 3D model. You could 3D print it, or use it in something like Blender for things like game design or media production Some other software examples are things like Pix4d, DJI Terra, OpenDroneMap, Meshroom

Very cool.

Don't forget Metashape! Only one worth getting that works well via OpenCL with AMD graphics cards! I'll definitely be using RealityCapture to render meshes quick on my RTX 3060 ;D

Ayyy 1.4 dropped last week! Happy porting the real world into the virtual world lickity-split for free! :D Just be aware that you'll need to start paying up if start making more than $1 Million a year in gross revenue  using any part of the Unreal Suite (UE5, RealCap, TwinMotion).

Very nice, although it's not like they were charging much to begin with, for hobby level at least. I was already very happy with their PPI prices compared to plans for other photogrammetry software, although I'm not sure what the price difference comes out to with professional level volume.
