[QUOTE="zero_zero, post: 301518, member: 9932"] They left for the long weekend already...Banghead After digging through the net for hours, I came to a solution... :Rock: I knew I needed a feew beers to clear my head. It looked like the vertices were all there, only the facets were missing at some areas. After importing it to Meshlab, I started by getting rid of the single large triangle on Q2. [ATTACH type="full" alt="32479"]32479[/ATTACH] Next, I exported the point cloud only , then re-import it again [ATTACH type="full" alt="32480"]32480[/ATTACH] Next I used a function to recalculate the normals for each vertex, need to be able to re-mesh the data. The "hairs" are the normals [ATTACH type="full" alt="32481"]32481[/ATTACH] Meshlab has a convenient function to recreate the mesh called "Screened Poisson Surface Reconstruction" which does the trick, although it takes a few minutes to compute. [ATTACH type="full" alt="32482"]32482[/ATTACH] The result: [ATTACH type="full" alt="32483"]32483[/ATTACH] After inverting the normals: [ATTACH type="full" alt="32484"]32484[/ATTACH] Turned into a solid model with Meshmixer... now's off the the printer and I am left to enjoy my holiday Cheers [ATTACH type="full" alt="32485"]32485[/ATTACH] [/QUOTE]
