There are a number of applications where measuring the volume under a mesh surface is important – volumes of stock-piles is a common industrial example. A standard procedure for measuring volume is to first determine a reference plane and then obtain the volume of the mesh surface above that plane. This tip video first shows […]
In the PhotoModeler Tip #32 video we demonstrate a feature new to the 2013.0 release (Feb 2013). The new feature is called: the 3D Plane. 3D Planes can be created on coordinate planes, or fit to three or more 3D points. PhotoModeler has a number of surface types (single triangle, triangulated paths, lofts, sweeps, NURBS […]
We have a short and sweet tip video for you this week. Just 41 seconds! Many objects in PhotoModeler – points, curves, edges, cylinders, surfaces, DSMs, etc. – have unique ID numbers. These numbers are set automatically by PhotoModeler. While working with your project, e.g. referencing points, deleting edges, etc. gaps will form in the […]
The Impossible, a movie starring Naomi Watts and Ewan McGregor, based on the true story of a family’s experience during the 2004 Indian Ocean tsunami, contains key sequences that PhotoModeler helped produce. The Impossible’s visual effects team, Le Ranchito, based in Madrid, Spain, used PhotoModeler to help produce the critical models for the flood and […]
This tip is a follow-on to the Tip 29 blog posting and video. In Tip 29 we showed how the new Sphere Target can be used in PhotoModeler to get precise photogrammetric marking and measurement. Some laser scanners, such as (but limited to) the Faro Focus 3D, can also use sphere targets for scan alignment. […]
Precise 2d marking of points in photos is key in a photogrammetric project to obtain the highest 3d accuracy. There a number of ways to get this marking precision. The highest precision is obtained when PhotoModeler can use a known target shape for sub-pixel marking. Sub-pixel marking means that the program can detect the position […]
This tip video is a milestone for us as it marks our first full year of tip videos, one every two weeks. We trust you like watching them and find them useful. Drop us a line or add a comment below if you have any suggestions for future tips. In this last tip video of […]
This PhotoModeler tip video demonstrates shortcuts for working with Layers and Materials. Layers are user-defined groupings of objects in your project. Layers can be used to control visibility in the 3D Viewer or to control what parts of the project gets exported. Materials are used to apply colors, surface appearances and textures to the objects […]
UAVs (Unmanned Aerial Vehicles) and drones are big news these days, not only in military use but more so with many new commercial and public safety applications. With cost-effective fixed-wing and multi-rotor UAVs capable of carrying camera payloads coming on the market, the sky has literally been opened to new possibilities! Aerial photogrammetry was once […]
In this tip video we show how to create a 3D profile of a PointMesh in PhotoModeler. A 3D profile is like a contour line but instead of being a line from a set of regularly-spaced heights, it is a single line at any orientation defined by the user. It is the 3D curve that […]
