Do you think they are suitable for creating types of textures that we don't have yet (are could be improved)? As I see it, these photographs don't add much to what we already have, but I might be wrong.

Honestly I have no any idea which material was used for the textures that FlighGear currently includes so I can hardly guess how much these aerial photos can contribute to improving the current set of textures. Still I think it's notable that the colours on these aerial images differ in a significant way from what we currently have for agricultural areas although I don't know if our landuse data allows for differenciating between predominant presence of grassland or fields, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

So far it looks like this: view nameCamera View/camera internal type=boolfalse/internal config from-model type=booltrue/from-model from-model-idx type=int0/from-model ground-level-nearplane-m type=double0.2f/ground-level-nearplane-m x-offset type=double0x-offset y-offset type=double-1y-offset z-offset type=double0z-offset /config /view So far so good... now I'm trying to change the pitch and heading defaults of that camera. I've tried eye-*-*-path and default-*-deg but none of those seems to have any effect... What am I doing wrong? Birger I'm not sure if this was answered or not...been out of the loop for while now. You needed to specify this as a lookfrom view type (similar to cockpit view). Then you sould be able to specify offsets (e.g. pitch-offset-deg, heading-offset-deg) which will affect the direction of the camera. As far as your question goes, my guess is you have misunderstood the purpose of the eye path settings. These just specify where in the property tree the value for position or atitude of the camera (or eye) is stored. In this case you don't need that. Just use from-model-idx number 0 as you have. This indicates the position and attitude data is retrieved from the same location as the primary FDM's 3D Model Location (e.g. /orientation /position). In other words, this camera eye location and atitude is the same as fdm location and atitude, because it is attached to the aircraft. You only need some small adjustments to offset the camera from the origin of the FDM (and 3D Model). The x/y/z-offset-m properties are for adjusting the location down to the desired location below the aircraft. Looks like you got that. The pitch/roll/heading-offset-deg are for making the camera point to a direction different than the aircraft is pointing. Straight down would be 90.0 (or maybe -90.0) pitch-offset-deg. Note, you will probably want to make that 89 degrees or some value not quite 90.0 because of the singularity issue that we run into with the matrix methods.

I'm sure this has been brought up before, but has anybody ever really *tried* to ask companies that sell satellite imagery on CD-ROM for their permission to use derived work (= FG textures) freely in an opensource project ? As long as not the actual product itself can be re-created from the derived textures, it should not be SUCH an issue, to allow an opensource project to use that kind of data, maybe one could in exchange offer them to mention them in some kind of supporters dialog within FlightGear or anything like that (which brings us back to the ads discussion ...)
