Cheap 3D Scanning..
show user profile  ScotlandDave
Didn`t have much knowledge on the subject of 3d scanning so did a quick google of it and read some basic stuff about laser scanning and also some of the software available for converting photographs into 3d ( ie photofly/123DCatch etc )..

This laser scanning thing seems an interesting/cheap way of scanning objects - i`m guessing even if at a lowish res these could be retopo`d easily enough.

Anybody messed with 3d scanning?

Only thing i`ve really tried is capturing point-cloud meshes with the Microsoft Kinnect, which was pretty low res.

Here`s a free piece of software that lets u use a webcam and a cheap laser-pen to scan and there`s some example meshes on the site:

Also here`s an interesting link with some of the stuff Autodesk Labs have been developing. Seems they`ve thrown away more groundbreaking technology than they`ve actually implemented:

Not personally, but have also been keeping an eye on the tech... ever since that australian video came around boasting limitless detail and no poly limits - they said they were scanning their assets in, which piqued my interests...

Seems to be going the same way as 3d printing... super high quality = super high prices... diy alternatives, cheaper, poorer results etc etc

I used the Autodesk 123D service for a while, then got bored of it. It can make some good results, but I didn't really need it for more than just basic experimentation.

I would like a local version of it that didn't require the cloud.

Ok I'll bite

The 'firm' looked into this as they want everything precise (but to look like call of duty...sigh.. they just don't get it)

for example the SA80, most bits are machine built so very precise measurements but then you have the handle which is a very organic shape. My collegues down in bovington got some guys ( in and had a demo then asked me to look into it.

After a bit of research I decided not yet. Its getting there but what it does is makes the mesh VERY busy. If like me, you like/have to have a clean mesh (because the software that they view it on is very fussy about having a clean mesh) then its not for you. It adds so many vertices that it would take about the same amount of time to clean as to make, effectively making it useless to us as it is.

If on the other hand you are not fussy about the mesh and care only for the render then look futher into it.

I will look into it again in a year or two but for us atm it's not good enough yet.

I saw a website a while back that had some very high res people scans, looked amazing. I think the used an array of DLSRs and some software similar maybe to 123D.

Might have been these guys, though I remember the site looking different.

missy is retopo not an option? ie once you have the scan, you basically resurface it with clean topology..

Bishbash - cool website :)

I played with the "Dave Scanner" mentioned above but the results were less than promising. It was able to read color, but the resolution is so dependent on the webcam that the low quality cam I had was just not able to create anything useable, no matter how simple object was.
Also, the size limitations were a large factor in not pursuing it further.
Perhaps if I had an HD camera and a stronger laser, it would provide better results.
It also can't handle transparent/translucent surfaces at all, so you really need to literally paint it matte white.

Yeah i`d read that on the forum - hair for example. I think some digital camera`s have a webcam function ( rather than using a dedicated webcam ) might be much higher resolution..

Tbh, for me it was yet another step..For the amount of money they want, i want it to be like 'ronseal'*

(For those not in uk, ronseal have a strap line...'does what it says on the tin')

Lazy? Probably but if we are going to spend that amount of money I want good results straight away.

what's the end product, if you don't mind my asking? simulator stuff?
