Photo based 3D Reconstruction on Portable Devices

Microsoft Research has released Information about a 3D Reconstruction App that runs on Windows Mobile. As far as the technology is concerned hardly anything new. It’s basically the same as Autodesks 123D Catch that is available on severall platforms with the actual image processing happening on the server.

The App looks very nice though, it comes with an acceleromteter supported visual guide that helps the user to capture all required images for a successfull 3D model construction.

DIY Volumetric Display

A beautiful volumetric display build from a screen rotating at high speed. Interesting idea, I don’t want to be in the room if there is a mechanical failure though.

 

Another take on the volumetric display concept comes from Sony. The prototype  rotates vertical lines of LEDs around its center to form a 3D image.

Desktop Map Renderer

TileMill is a free Open Street Map Renderer for OSX, Linux, Ubuntu. It allows to edit the styling off the map in a comfortable editor. Maps can be exported to PNG, PDF, SVC etc.

Maperitive is annother application in this category. It’s also capable of exporting 3D Terrain Data as a textured COLLADA mesh

 

 

Voxel Renderer for massive Geospatial Data Sets

News from the famous voxel rendering engine Unlimited Detail by the australian company Eyclideon. Deemed vapor ware by some they have now released information about Geosphere a software for viewing large geospatial voxel data sets. The technology can now also be licensed in form of an SDK.

Still some of the criticism, eg. that animation and lighting can’t be done in voxels, voiced by people like John Carmack might be right after all and the reason for the shift from the field of gaming to geospatial visualization where this is not a requirement.

Still very impressive:

Open Source Kinect Fusion – Update

There is an update on the open source implementation of Microsofts Kinect Fusion Algorithm by developers of the open source Point Cloud Library.

They improved on the Microsoft implementation with their algo called KinFu Large as they are able to scan multiple volumes in on pass allowing to scan larger scenes in one go.

The point cloud library (PCL) is available as prebuild binaries for Linux, Windows and OSX as well as in source code from their svn repository. The code relies heavily on the NVidia CUDA development libraries for GPU optimizations and will require a compatible GPU for best results. Information on how to setup your own build environment and the required dependencies is available from their site.

Besides the Kinect the library supports several other sensor via OpenNi.
