Software

  • Photogrammetry is now free for everyone courtesy of Acute3D. At SIGGRAPH 2014 the company announced Smart3DCapture Free and Basic editions (the latter costs 199€). Photograph an object from as many angles as possible and use the desktop software to turn them into a 3D model. [Gonna have to try this.]
  • Polygonica is software for working with faceted geometry data.
  • FlowVision is a finite-volume CFD solver written in C++ and delivered in both serial and parallel version.

Technology

Meshing the Walls

Part interior design, part sculpture, all mesh. The basic forms of this wall-mounted tet mesh seem easy enough to build and install but if you watch the video you’ll see that the manner in which it is lit is an entirely different story. It’s all from an artist group called Antivj.

    A quick comment on Smart3DCapture: Autodesk has offered a similar service called 123D Scan for a while as part of their 123D product suite. It has two versions: an iPad/iPhone version and a desktop based on. I played with it for a while – see http://youtu.be/Cn7rKDp2xVY for my best example.

    My feedback is:
    – Expect the first three scans to be really bad – part of the learning experience;
    – Lighting, focus and picture resolution are key – ie forget about outdoor scanning, using the iPad/iPhone version;
    – Overall it is an interesting tool to have, and great to have a starting geometry, but cleaning will be required if accuracy is required.

    Scanning using Xbox Kinect sensor is also an option as it offers more control and a better accuracy for a cheap price – but it has its pitfall as well…

    Thanks, Julien. The article says that Acute3D is the source of Autodesk’s capabilities.
