Re: [osg-users] [vpb] Quesions about LOD in VPB

This is nice but what I'm using this for is something like a Google map. You see it from a high view and it you can close in on an area in the terrain. So I don't mind using the full range of level of detail. I was under the impression that you had to set the level of detail get the most detai

[osg-users] CubeMap with multiple displays

What is the best way to use a cube map across multiple displays? Ideally, I think that generating the cube map on one display and then sharing across the others would be best, but I haven't been able to make it work. Mark ___ osg-users mailing li

Yes, I think so. There is also this command which may be interesting for you : --levels Specify the range of levels that the next source Texture or DEM will contribute to. http://www.openscenegraph.org/projects/VirtualPlanetBuilder/wiki/CommandLineOptions -- Christophe 2012/10/31 David Gl

Re: [osg-users] [vpb] Quesions about LOD in VPB

O.K. Then the -l command sets the limit of the LOD you can have and not how many LOD's your terrain is going to have! By default it maxes out at 30 and the only reason to use it is to limit the LOD's (and detail) of your terrain, Right? D Glenn declic creation wrote: > Hi David, > > If osgdem

FYI, it looks like Stephan's FlipsideView example is broken in iOS 6. I get an error when trying to add the view: Code: -[UIView setRootViewController:]: unrecognized selector sent to instance 0xca36f0 2012-10-31 11:53:50.850 viewtest[2745:907] *** Terminating app due to uncaught exception 'NSI

Hi Jorge, I'm sorry I keep bothering you, but I can't find the documentation that you're talking about. There's nothing in the folder where the examples are that I downloaded from the openscenegraph website and I can't find any other sort of documentation. Could you please be so kind and provid

[osg-users] Questions/proposal for readImageFile() - Detect unloaded images

Hi all, Here is a problem to solve : how can you highlight surfaces where textures didn't load properly (missing file, read error...)? My first answer was to create a ReadFileCallback, and make readImage() encapsulate "default" call. If call fails, then I return a "dummy" image (1x1 pixel, flas

I appreciate your answer. I understood that I should firstly read books before asking silly questions. That's happened because I tried to understand OSG using BlitzBasic knowledge :x -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50911#50911

Hi David, If osgdem get to the level where the texture resolution is the highest it stops, even if it's before the max number of levels you specified. So L11 might be the last level with the highest resolution texture for your database. -- Christophe 2012/10/30 David Glenn > > robertosfield
