All work fine, even when mixed in a single project !īut I’ve also used the D300 ( Beynac), and even my smartphone, although the picture quality of the phone isn’t that good, and it appears in the scan : this sphinx was shot with my smartphone :
I usually shoot with my Nikon D800, and focal lengths ranging from 14mm to 200mm. Now you have a lighter model that is easier for sketchfab to handle. So finaly to sum up an old rig I’ve done:Īs you can see, I used Zbrush to retopo the model and bake the normalmap with Xnormal. Most of them don’t like turnatble since the backgroud is fixed, the reconstruction will failed so you need to mask the object, so that the soft can align photos only with informations on your object. Why ? You will used it to do an automatic masking of your object on all your photos, it’s a real time saver. Most of the time I remove the object without changing the lighting conditions and the camera preset !

Then you take a photo each 20° angle and import the 18 photos into your photogrammetry software ! I will recommand a DSLR or an hybrid cam.

In photogrammetry, the key is the sharpness of your photo ! So try to shoot at aperture f18/22 and iso 100 ! To have this conditions, a point and shoot or a smartphone camera won’t be good. Then you put your object in the middle of your turntable and place you camera on a tripod. Some lamps to get a homogene lighting on your objectĪ turntable where you can stick a with paper with graduationsĪ nice white backgroud, I used this box with a big light behind to get a clean white backgroud. Most of them are done using a very cheap equipement from ikea I’m using agisoft photoscan in combination with Zbrush to clean my scans ! Photogrammetry is the technique to extract geometric information from two-dimensional images or video. Wikipedia has a great list of software options:Įn. Comparison of photogrammetry software

You can use pretty much any camera to take a series of images and then use software to build your model. Photogrammetry is a very commonly used 3D capture method. We realize the Artec scanners are too expensive for most hobbyists just getting started in scanning. MARI is also a great dedicated digital 3D painting program. ZBrush is great for sculpting geometry and painting or projecting texture. If you had to dust the surface or if your scanner does not capture color texture info, you can add material types and re-paint texture digitally if needed.ZBrush also has an intelligent decimation tool called ZRemesher that does an incredible job of reducing a mesh while keeping the fine detail. The Artec software does a great job of reducing models. Reducing the polygon count will also reduce detail, though. Many of the scans are millions of polygons. Once we have the digital scan, we usually decimate the model.Again, increasing scan sensitivity with the Artec scanners helps with this. Most scanning applications approximate the hair shape and product decent results. Hair and fur is always difficult to scan due to the extremely fine details.Again, you have the option of dusting the surface and/or increasing scan sensitivity in the case of the Artec scanners. Very dark surfaces can also be difficult for laser and projected light scanners.You can spray these objects with gray primer or, for a less permanent solution, dust the objects with talcum powder, corn starch, etc. Shiny, highly reflective, or transparent objects can be difficult to scan.We’ll be posting some of those at some point in the future.īest practices for scanning and post processing with Artec are similar to other scanning technologies: We use the Artec Eva for larger items with less detail. Small meaning most items that would fit in a 12" cube. Most of the smaller objects we upload to Sketchfab are scanned with an Artec Spider.
It also briefly shows what the scanning process looks like with the Artec Eva: Here is a quick video we did that gives very simple info about 3D scanning. Artec scanners have the added benefit of capturing color texture during this process. One or more geometry cameras measure the distortions in the grid to measure the object and build your point cloud. These scanners use a projected light pattern as opposed to a laser.

Full disclosure: We do distribute for Artec. We use Artec scanners to capture objects. There are numerous scanning technologies out there that all have advantages and disadvantages.
