I was unable to find a tutorial on making the bottom of the 3D models that were impossible to photograph solid. Right now, it looks like you can see up into the model. While this is sometimes cool, it would be nice to figure out how in RC to “close off” the models interior, for lack of a better term.
Hi Julie Scott
Can you please redefine the question as its hard to understand what are you looking for.
Set your reconstruction region in such a way that the bottom of it is at the level you want the object to be closed at.
Then do your reconstruction.
RC should generate a closed, watertight mesh automatically.

Thank you. I will try this.

The last model I made, it appeared the bottom of the object was open when viewing from underneath. That was the part of the object that I was unable to photograph. I was hoping some sort of automatic mesh appeared on parts of the object/subject that weren’t photographed. I may have just set my reconstruction region too large and will now attempt to correct my issue with that.

I’ve tried this an not succeeded. Here is an example of what’s frustrating me in a model I just made. It looks “open” from the bottom when in reality it is not.

At what stage in the process should I be setting the reconstruction region to cut off the parts I don’t want and “seal off” the model so it doesn’t appear like you can just look inside it?
I’ve been doing it thus far post-texturing. Should I be doing it earlier? I save it till then normally because I’m not sure until nearly the end which parts of the model I do and don’t want to keep. I often use the filtering tool to cut off bits and pieces, but doing this seems to “open up” the model to be able to peer inside it.
In that case you may want to try some post processing in something like Meshlab.
That will allow you to close such holes.

I was afraid of that. If all else fails I’ll download Meshlab.
It’s a little frustrating, because I kind of did it by accident with this model, and I can’t figure out how to recreate the circumstances that led to it:

Hi Julie,
very nice model!
And scan btw…
Is the mummy on a large pedestal or just a slab on the table?
Did you try to make the reconstruction region as small as possible and also as big as possible?
What you see on the bottom is the standard “hull” that RC creates on every model alont some of the bounding box faces, so that a closed mesh is created.
Often it is on the bottom, but sometimes it wraps itself around the top.
My guess is that the result is random to a certain degree, so it might be worth to play around a bit with the size…

Thanks, I will start playing around with size.
