3D Scanner from Next Engine Question
(OP)
We are considering purchasing one of these items and I wanted to poll the masses for thoughts on this thing. Anybody using one now, and what do you think of it?

RE: 3D Scanner from Next Engine Question
With any scanner of this sort, you'll need to consider the disadvantages. For instance, if you want to scan something like an action figure, I think you'll have difficulties--since the scanner cannot see the under/back side of an arm or leg. Since that's true, it will also be true for similar geometry where some part of the object obscures or covers another part. Perhaps by stitching together several scans from several views this can be overcome--something to ask them about. (See if you can get a scan of a Star Wars action figure or something.)

RE: 3D Scanner from Next Engine Question
It took us a while before we got it to work properly. We are still trying to master it (or at least use it ''fluently'').
I think it might take us a long time before we scan something as easily as the guy does in the demo video.
(But we can't exclude the possibility that we suck!
RE: 3D Scanner from Next Engine Question
A JOKE. Nice try Solidworks.

RE: 3D Scanner from Next Engine Question
I would like to see one that would scan all around the part creating an even 3D part.

RE: 3D Scanner from Next Engine Question
First of all, we have all upgraded our workstations to 64bit Windows XP. Well, NextEngine requires 32bit, so I retained one of our older workstations. Unfortunately, I had to then upgrade this older workstation to 2GB RAM and the latest version of USB.
I am paying an additional $3500 for the Office Premium upgrade, so the running tab no this thing is not only the scanner, but the upgrades to the workstation as well as the SW software upgrade.
We are playing with it now, but cannot use the geometry to create machinable parts. For that, we must revert to our microscribe for a timely prototype turn-around.
I'm not dis-satisfied, just telling you all of the hidden little items that may bite you. We are working on getting this up and running, any helpful advice would be appreciated. Also, if you are using it successfully now, I would even be interested in paying anyone a visit to learn up on how it's done right (of course, as long as we're not competitors)
Also, we had to re-install an OLDER version of the NextEngine software because the newset version has bugs. Nice.

RE: 3D Scanner from Next Engine Question
If you need RE and Inspection and you got 50 for a Minolta Digitizer and $$$ Rapid Form XOR then scan away. (we all don't build turbine buckets looking for crack propagation)
I think the only reason its been called a toy is becuase we haven't been let under the hood completely. Its new and it makes no claims to be a full RE solution, Just a cost effective one for the time being. If I could upgrade and get the Scanto3d I'd probably still use the 3d point import macro, and STL graphics file, seletion filters, and insert curve through reference points.

Hi Matt!
We also have now the scanner and try to scan a shoe. However, the results are poor (lot of holes).... :(
I think we didn't have a right setup. So may I can ask you, how you did the scans?

RE: 3D Scanner from Next Engine Question
Michael and I walked through this together, and he's up and running now.
For others interested in scanning shoes, here's the steps we went through
(with pictures from a shoe I scanned).
1. Run a 360 scan with 7+ divisions (position shoe with corner pointing forward)
ht
2. Assemble the 360 scan, by placing 3+ pins on common features

3. Trim gripper + some extra overlap

4. Scan heel and toe using "bracket scans" (assemble + trim like 360 above)

5. Attach heel and toe to rest of the shoe (for shoes, use 5+ pins)

6. Blend (manual trimming of extra overlap will increase quality)

RE: 3D Scanner from Next Engine Question
vince,
His work on the model or the software?
Not a nice comment!
I think he did great work. For what the 3D scanner is capable of, I think Nick went beyond that and did a great job.
I give him a star!

RE: 3D Scanner from Next Engine Question
I went to a demo on the Z Corp scanner yesterday. Quite impressive, I must say, but the $40K it costs would be difficult to justify. The demo consisted of calibrating the scanner, doing the scan and importing into SWX. After about an hour and a half there was a solid model of one of the oversize fist toys (Thing from Fantastic Four, I believe). It's absolutely awesome technology, particularly for a first pass at it.
The Scan to 3D add-in really does automagically generate a model. Granted, it basically plays connect-the-dots with the point cloud data, so you end up with a model with thousands of faces. The add-in even filled in holes in the scan and completed (with one crappy surface patch) the interior area of the part that the scanner couldn't get to.
If you needed Class A type surface data, you'd have a ton of cleanup to do (and you wouldn't be using SWX), but if you just need to design around something you could do that easily. You don't need the Premium module, because the scanner does output STL files, which you can import into SWX and get a tesselated model provided your workstation has the horsepower. The add-in just provides more tools to manipulate the scan data.
RE: 3D Scanner from Next Engine Question
you could look into leasing from Z-Corp. I think they have a plan to lease to purchase. if you want to purchase. Sort of like a car. A cheaper way to go if your company wants to try it. Just give it back after the lease.

NE Nick- try and sell and demonstate your scanner on places other than this forum.

RE: 3D Scanner from Next Engine Question
I wouldn't say the polygonized model has no use in SWX, it just depends on what you're attempting to accomplish. If you are trying to reverse engineer a product for the purposes of modifying it and creating something new, you're 99.9999% correct - might as well model it from scratch. Same goes for trying to re-tool an existing part.
If, however, you simply need to design something around an existing part, the polygonized model will get you something a lot quicker than modeling from scratch.
Bottom line, if you need actual toolable/usable/modifiable surface data from a 3D scan, this product won't get you there automatically. Then again, SWX isn't the surfacing tool I'd choose for this either.

RE: 3D Scanner from Next Engine Question
The shoe looks good, which means it has a high polygon count or is using graphics card shaders. A high polygon count is very heavy on SW. The scanto3d add-in doesn't do that well either, and trying to surface these polys ends up making you wish you hadn't tried. Good RE packages can recreate things like a shoe to the point where parametric feature based geometry can be easily created from the final product.
There are a lot of people out there who don't understand the difference between polygons and nurbs models. They don't understand how hard it is to go from polys to nurbs. the tessalation of nurbs to polys is happening right in front of your eyes every time you use SW.
I'd rather pair that scanner with Maya, or 3ds for some graphics, or try it with some top of the line RE software. The Next Engine scanner may be a good scanner for the money. The Next Engine Scanner may clean up the points and use Delauney triangulation to make a watertight polymesh....but the Next Engine scanner paired with SW is not a good solution to go from polys to nurbs if thats really what you want to do. An hour on google with the work Reverse Engineering will show you the way.

RE: 3D Scanner from Next Engine Question
Ok, now my view of point:
- As always, there is the question for what you need the scanner. In our case: We wanna get a 3D-Object from shoes to animate them (in Maya and also as lowres for web-content). So there is no need to convert the Poly to Nurbs. Today the scanner is the best solution for our needs. No need to spend 30k (Konica-Minolta) to scan the products and we also have texture informations.
- In my opinion the Software from Nextengine isn't finished yet. There are several points which where either a "nice to have" or are essential (esp. for trimming). However, this is a young product and so I'm looking forward.
- We also need some shoes as a nurbs modell. There I agree to model them from scratch by hand. This takes three days by one guy and we have a fine model with good patches. We have no experiences with solid works and may I'm wrong.
- support: For us it is very important to get a good support. And I can tell you: The guys from nextengine try their best! Thanks to Nick!!! I asked about some hints and get a tutorial he did for me. We use some Software (with no hardware) which costs a lot more than the scanner (inkl. Software) and have no support like this.
Conclusion: If you wanna scan some items for 3D Animations or web content You can't do wrong with this scanner.
Just the first steps:
