Fiere Margriet

Amazing projector project by Mark Florquin uses ReconstructMe for 3D scanning:

We projected the story of ‘Fiere Margriet’ on a small but charming street (Eikstraat), during Leuven in Scène 2012. ‘Fiere Margriet’ (Proud Margriet) is an old legend from Leuven. In short it tells the story of a young lady who gets mugged and killed by a gang of thieves. They dump her into the main river in Leuven, De Dijle. Her body doesn’t sink however, but floats miraculously upstream, surrounded by a magical light.

In their making-of video gives an idea on how ReconstructMe was used to digitalize the womans body in different poses.

Surface Reconstruction

While making some serious progress on texturing scanned surfaces, we ran into need of a more decent surface reconstruction and decimation technique. Until now, exported meshes contained hundreds of thousands of triangles, adding unnecessary overhead in regions that could be expressed with just a couple of triangles (e.g planar regions). Additionally, we felt the need of closing small surface holes in order to allow smooth texturing across the surface.

Therefore we re-designed our surface reconstruction pipeline to support more sophisticated reconstruction techniques and a configurable surface decimation pipeline.

Below is an image that shows the original mesh as generated by the current version of ReMe (v. 0.6.0-405). It contains roughly 250.000 faces and one can clearly spot the holes that remained due to the lack of visibility of these areas while scanning.

In contrast, the next image shows a successful reconstruction of the original surface reduced to 50.000 faces with boundary holes closed.

Comparing both meshes using the Hausdorff distance gives an average distance of 0.8 mm. The image below colorizes the distances (blue low, red high).


Surface reconstruction isn’t limited to individual meshes, but can also be used to fusion multiple volumes into one single consistent mesh. The image below shows two individual stitched meshes using ReMe’s --multiscan feature.

Here is the fusioned mesh as generated by the development version of ReMe

Stay tuned!

On Making Things Matter

Taken straight from Thingiverse

Mike Moceri and Tom Burtonwood collaborated on a project that premiered May 26th at The Southside Hub of Production for the exhibition “On Making Things Matter”. We 3d scanned (with the Kinect, Reconstructme + Netfabb) visitors at the opening reception and then 3d Printed them with a MakerBot Thing-O-Matic. All the “portraits” we scanned are uploaded to Thingiverse to share with teh internets. We have also scanned portions of the exhibition and the interior of the building and we will be installing 3d prints of these vignettes over the course of the exhibition.

Here’s a video (you can see ReMe in action at the beginning of the video)

Mike attended the Zhou B. Art Center in Chicago participating in an event called Facemask. More on this including a video stream can be found here.

Tech Preview – Surface Texturing

Thanks to all that contributed in our feature survey on Google+. We adapted our internal road-map due to it’s results and will head for texture support and an easy to use graphical user interface next.

Even though it’s still early days, we’d like to share what can be accomplished using our texturing engine. We are aiming at a semi-automatic solution where users are attaching textures through a post-processing step. This allows us to use arbitrary cameras for texturing the mesh. Our engine supports multiple textures and combines them smoothly.

The first image below shows the plain surface reconstructed in high resolution mode. Next to it an image taken with an Casio Exilim ZR 100 to be used as texture. On the right the final textured mesh is shown.

The best part about it, it took less than 3 minutes from scanning to texturing for the above scenario. We will probably release this feature alongside with the first version of the UI around late summer.

Enjoy!

3D Doll

Mark recently uploaded a scan of Doll made using ReconstructMe and ZBrush for texturing. The result looks amazing

Here’s his info text

3D scanning is usefull for reproduction & preservation. The model was scanned with the Asus Xtion Pro Live 3D Camera en processed live on a laptop with ReMe Software. Pictures were taken with a Nikon D700 for texturing in Zbrush. Using the Spotlight feature in Zbrush the textures were applied on a subdivided mesh and retopologized.

Isabelle Body Scan

Mark posted a full body scan of Isabelle yesterday. Here’s the turntable animation video

I asked him for a statement on the required post-processing. Here is his full answer quoted.

[…] I’m impressed with the perfomance of ReconstructMe! Can’t stop scanning.

[…] After a few scans I found myself moving away from stiff “standard poses”, to more inspired ones, like a photographer would do. Its so much fun, scanning in 3D!

[…] Some post-proces info: I’ve applied smoothing here and there in Zbrush in addidition to Standardbrush adding – substracting to enhance the wrinkels in the clothing. Then scan was made with the “human” config settings, The face comes from a different scan.

Here are two more turntable animations of Isabelle

Long Night of Research

The long night of research (in German “Lange Nacht der Forschung”) on Friday last week was a great success for PROFACTOR and ReconstructMe. We had around 300 people visiting and exploring our robotics, nano-tech and chemistry labs.

At the ReconstructMe booth we had a lot of fun reconstructing our visitors and enjoyed the in-depth discussions with potential users and developers. What really surprised us was how quickly people learnt to use this new technology to scan their family members.

We used the swivel armchair setup to speed up the reconstruction process and provided each visitor a personalized 3DPDF containing an embedding of their reconstruction. Here are two such samples: one, two (Acrobot Reader required to view the embedding)

Here’s a video made at the event
