How to 3D Scan All Sides of Objects - RealityCapture

Today's tutorial is all about how to scan the bottom side of objects using photogrammetry in RealityCapture. Creating closed 3d models is immensely useful for 3D Artists, so using this technique/workflow should be tremendously helpful! You can then export these models to any package of your choice, whether that is Blender, Unreal, Maya, 3dsMax, whatever! These images were then rendered in Unreal Engine 5 using Nanite.

William, you are a gem of a human being. I began my photogrammetry journey with you after years of failure. My scans are now GORGEOUS after watching your videos and following your advice. Thank you so much for the time you put into these. If you ever wonder if they make a difference, let me assure you: they do. Thank you a million times.

[VidFreak]

You just saved me from 3 days manual work I would normally do in Zbrush . Fantastic vid and VERY well explained. Many thanks, bud!

[Marco-bjct]

Many other tutorials over same arguments but William has lot of empathy for us. We can feel it. Thanks William. Number one.

[mayorandres]

thank you so much, your video has helped me perfection prehispanic historic pieces for a museum in costa rica.!!

[ROYSMoGraphDesignk]

we going have just tired to model manually !!
It is unimaginable how much this thing is *_full of help_* and saves a lot of *_Valuable_* time ..
Just Awesome ..

[VIRUSMUSICc]

Thank you man its really helpful 💖 a life saver

[EMNM]

I always like the vid before watching Will is just amazing. Thank you

[richard_wenner]

Brilliant, thank you. So good to have a complex function broken down and explained graphically.

RealityCapture has a very good ability to auto detect "irrelevant" parts of scans on rotated objects and remove them when using a bright uniform background. I use a Foldio3 light box with a turntable for my small object scans and I can just do a full rotatiom of pictures, flip the object over, and repeat several times if needed and when RealityCapture builds my object it just ignores the bright white background/turntable automatically and gives me a perfect scan without any manual work needed or any multi-scans or object masks or multiple mesh building.

[antonios]

nice, i'm using this technique on another photogrammetry software but thank to you, i'm now able to use this in rc

[doctordarre]

TNX a lot for a very comprehensive tutorial. You have already answered many of my questions.

[scarabrae]

'one dark frame in-between' great tip

[Jim]

again a fantastic video William, thanks very much, cheers mate

[tahaabolfazlmohamady]

great tutorial also your voice and background gave me cozy vibe thank you

[dzezonja]

Thank you so much for these tips, I've been thinking for a while to scan my first object and will surely use your advice!

[wsterlingy]

You have an amazing gift as an educator

[TLabsLLC-AI-Development]

Another solid video friend! I'll be getting final models up soon as I finish marketing planning. Then I'm building a database of 10k models per year and building experiences using these assets.

[degeneraturat]

Thank You, really helped me with scanning quite soft, fabric suitcase.

[elminkaraev]

It was very interesting. thanks for the content William.

[TXanders]

Nice to see more traditional photogrammetry videos coming back up, great stuff as always William!

I'm not familiar using RC as much as Metashape/photoscan, but there may be some image culling features to help cull overshoot or lowimage quality estimation issues that can also stagger scan results ( or cause misalinments)

looking at the control point segment, there is an accuracy reading going on.
Your 0.1-0.2px is accuracy to the matching control points so it may also be available at earlier photostages too, might be worth investigating.

Keep it up!
Nice to see you on patreon too. well deserved.
