Generating image collections for building structure from motion models is simple and inexpensive. These are two obvious appeals of the method for field recording. However, processing SfM models can require considerable computing power. That can make the method relatively inaccessible for some. In addition, once a model is generated it can be very difficult to share the model with others over the web. Screen shots generally do not do justice to a model. In theory embedding a 3D model in a PDF is appealing and elegant. Yet, in practice, I find it does not work very well. Often times the PDF is too large and it can produce what I call "a browser bomb".
Hypr3D offers some interesting solutions to both the high computing overhead and the difficulty sharing models online. Much like the Automatic Reconstruction Conduit (ARC3D), Hypr3D is an online cloud based service. In other words, the computing is done server side rather than client side. That's nice for people who can't afford fast computers with lots of RAM. Hypr3D also offers a very nice interface for displaying 3D models on the web. While I find that Hypr3D does not produce models that are as sharp as Agisoft PhotoScan, the advantages of server side processing and online model sharing are very nice features. Best of all, an image collection that is suitable for PhotoScan, will also solve in Hypr3D. Below is a model that is based on images that were collected for processing with PhotoScan and reprocessed using Hypr3D.

Huaca San Miguel is part of the Parque de las Leyendas located in urban Lima. The photographs were captured in collaboration with project director Lucenida Carrion Sotelo, colleague Gerbert Asencios Lindo, and colleague Margaret Brown Vega. Equipment used: Rokkaku kite and Canon S90 taped to a Gent-X picavet. The camera was running the CHDK Ultraintervalometer script. A large orthophoto was also produced from these images. The orthophoto can be found here. Huaca San Miguel is located in the Parque de las Leyendas. Here is a photograph of the camera rig.
