I was asked to 3D scan a professional rowing ore. Initially I tried to 3D scan the ore as is using the Artec EVA 3D scanner. I had a lot of trouble keeping alignment while 3d scanning the ore due to it’s length and relative lack of tracking points. I solved this by adding tracking markers and small white balls to the ore that I then could later use to align the scans with.
Below is all the scans I did of the ore.
After using the tracking points and the white balls to align the model I had an almost perfectly aligned model.
I processed a couple of scans at a time.
Then finally I merged all the scans into one single model. After this I removed the white balls from the 3D model as this was no longer needed.
The middle part of the ore needed a lot more detail. Thus I used my Next engine scanner to 3D scan this part separately.
Once done I imported and aligned this to the original ore 3D scan.
I used projection master to project the high resolution 3D scan of the middle part onto the full 3D scan I did of the ore to keep the model water tight.
Once done I separated the model into 3 parts for 3D printing.
I was also asked to hollow out the middle part to save on material. First I created an low resolution object that would be used to subtract from the middle section.
I also added some reference points to make sure the 3 separate parts would fit back perfectly once 3D printed.
Then it was over to the 3D artist to do the 3D printing and the mold preparation for the casting.
