Fyi, sometimes 3D scans have issues with things that are glossy/shiny/reflective.
Trust me when I say there are Zero times of the day in which you can take a scan of a 1969 Chevelle with metallic paint, and have the model generated in a way that DOESN'T look like the Incredible Hulk grabbed it and chucked it through the air.
At least you have a pretty solid surface, it just looks like it needed to be smoothed (which can be a pain).
My biggest issue (besides having a car that reflects everything) was that I tried to bypass actually getting a scanner, and I used sets of photos that I compiled into Autodesk 3D Catch to generate the models. But in the end, it was a good learning experience.
TBH, the BEST and easiest thing you could probably do, is use the scanned model as a template/base layer for a new 3d model, then create a second layer where you generate the shape and the polygons for the shape as best you can to re-generate the model.
It is essentially the 3d equivalent of taking a blank sheet of paper and placing it on top of another sheet of paper, and tracing the details of the lower sheet onto the upper sheet.
Ditch the lower sheet when you are done (aka the jagged scanned model).
Having the scans as a template to model from is a great way to ensure that you get all the proportions correct.
Alternatively, I used a pair of dial calipers and Lightwave3D at one point to recreate the torso of the 20th Anniversary Optimus Prime.
I might only have the torso, but it transforms!
It might have been easier to scan it, but you can't go wrong with owning calipers.
Additionally, some have found it better to keep the model fixed, and instead place the scanner on an arm that revolves around the object.
For the best results, you need to find a way to suspend the object you wish to scan.
Watch this:
Maybe it'll help you generate better models
