The new DIRSIG 4.4.2 release includes 10 new demos, bringing the total number of these feature focused simulations to 53. Some of these demos have been briefly discussed in other posts (for example, the expanded Geometry Primitives and Bayer Pattern Focal Plane demos). The following is a list of the new demos in the 4.4.2 release: Bayer pattern focal plane A set of example BRDF materials LIDAR returns from a sloped surface LIDAR returns from sub-pixel structures A geo-synchronous, exo-atmospheric "moon-like" satellite A 4-camera, division-of-aperture polarization system A 2x2 microgrid division-of-array (focal plane) polarization system An expanded set of primitive geometry objects An extended-area, directly viewable source An advanced UV mapping example Like the other demos included with DIRSIG, each demo is a self-contained simulation that can be easily downloaded (from within your local installation), unzip and run without any modifications. We consider t
A blog about the Digital Imaging and Remote Sensing Image Generation (DIRSIG) model featuring posts contributed by the developers. This is not a user manual and it is not a training class. But, it is a place to see what the developers are doing and a little about how we do it. So think of this as a place to learn cool tips, tricks, etc.
