It’s standalone application so you need to process photos on your own machine. In trial version you get complete application without limitations for 14 days. I’m using standard laptop (Core i3, 1.7GHz and 4GB memory) and still managed to get results in couple of hours.
User interface is very straightforward and with nice semi automated wizzards, so basically you manage things with couple of clicks, but it’s still very good idea to look at tutorials published on their site.
3Dsurvey team advices you to use ground control points instead of EXIF GPS data, so I did that.
Main advantage is that you are in control of whole process, so you can for example manually correct point cloud to remove parts that are not terrain (vegetation, buldings,…) and you can recalculate some smaller parts of orthophoto to select best available picture.
