Hi, Some quick answers for you:
>> . Any thoughts on how to specify textures at each of those levels? Can I >> specify each level with a different "-t TextureDir" argument? You use the '--levels' argument, one for each source. For example: --levels 0 5 -t GeoTiff1.tiff --levels 6 10 -t GeoTiff2.tiff --levels 11 15 -t GeoTiff3.tiff >> Also, is osgdem "smart" enough to figure out when the best time to show the >> next level is based on scale? In short, no. The longer answer is that all the infornation is actually available internally to osgdem but there is no mechanism exposed to use this info in the way you wish (unless this has chaanged since I last worked with the code) Cheers, Brad -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Chris Ess Sent: Friday, 9 September 2011 9:43 PM To: [email protected] Subject: Re: [osg-users] [vpb] Multiple maps in model with osgdem? (vpb) Thanks the responses everyone! This is actually very exciting news, as I was getting ready to redesign some software I have been working on to try to force the same effect (and the deadline is in less than a week!). Now, I will have to ask that you excuse my ignorance, but I am very unfamiliar with the vpb tool and mapping tools in general to be honest. The application I am using requires that I use VPB/osgdem 0.9.10 since we are using a third party library that runs on top of an older version of openscenegraph to display the maps. The command that I have been using to generate maps from the GEOTIFF textures I have is something like the following: Code: osgdem -o MyMap.ive -l 15 --compressed --skirt-ratio 0.0 --levels 0 15 -t MyGeotiffTextureDir I have looked up the command line options on the "Osgdem/vpbmaster Command Line Options" page I noticed there is a list /w a small description but it didn't seem very helpful unless you already have some experience with how the application works. I have geotiffs taken from a number of different scales (in separate directories) : 5M:1, 1M:1, 500K:1, 250K:1, 100K:1 ...etc I guess where I am getting confused is how I specify what scale of textures I want to show at what levels. Its my understanding that using the command above, I am currently generating 15 levels. Any thoughts on how to specify textures at each of those levels? Can I specify each level with a different "-t TextureDir" argument? Also, is osgdem "smart" enough to figure out when the best time to show the next level is based on scale? As far as the "popping" effect mentioned earlier, that isn't a concern. It may actually be better as our customers will be able to recognize when they are looking at different map data/scales. Any quick responses are greatly appreciated as I am under a bit of a time crunch! Thank you!
