Re: [osg-users] File Size Limit on OSG::Image?
Hi, Thanks for the response. For some reason I never thought about running out of memory, and I am only catching a general exception. I've been playing around with Photoshop, and just assumed that since it could open the image of that size, that it should be fine. Guess it uses a lot of the scratch disk for loading it since i just have an XP machine with 4gb. Looks like I'll have to try and locate a machine with more memory and Windows 7 then... ... Thank you!

[osg-users] File Size Limit on OSG::Image?
Hi, I am currently working on creating a poster image from several images and the file size is pretty large. Currently the one I am trying to create is 65250 wide x 22500 pixels in height (Image needs to be large) Currently I am doing the following: Code: posterImage = new osg::Image; posterImage->allocateImage( (mHeight), (mWidth), 1, GL_RGBA, GL_UNSIGNED_BYTE ); Right now it is giving me an exception when trying to allocate that image. Is there a size limit on it, or am I doing something wrong? ... Thank you!

Re: [osg-users] Creating Image from Openflight file
Hi, Unfortunately, I cannot as the only one I have is our proprietary one, and it is rather large. I am also not really a modeler, and don't have the tools easily accessable to create one. I did try an IVE file, which shows up properly in the viewer, but when I use my test program, it is missing a large portion of it, as well as some smaller pieces. Is it a correct assumption that the IVE contains all the data necessary, and doesn't need any external references? Again, this one is proprietary, but I can see if it happens with one that is freely available to use as an example. I will also work on piecing together a cleaned version of my test code, but it is very similar to the OSGPoster example in function (which also doesn't give me the correct output) Thank you!

Re: [osg-users] Creating Image from Openflight file
Hi, In looking into this a little bit more, it appears that it is not picking up a lot of the externally referenced textures and flt files. When i load the main FLT file, it will load in OSGViewer and show properly, but when I load it with my program, it seems to only load the the last referenced FLT file. The structure of the file is this: Main | +--+---+---+--+ #1 #2 #3 #4 #5 Each number is translated to it's proper position in the main file Another thing I noticed is that the FLT files are all built with the same origin, Meaning #1 through #5 are all built at origin 100,100 for X,Y. Not sure if this has anything to do with my issue, where they might be getting overlapped by each subsequent one when being built. Thank you!

[osg-users] Creating Image from Openflight file
Hi, Ok, I need a small program to go through an openflight database and produce tile images of the database at a specified size of 2250x2250. Each pixel will correspond to 1ft in my database. I have an example program that I made that will run with a small FLT file that is less than a tile size. It will also work when loading in a larger FLT file, but will only show one of the parts of the file, and will not show the other referenced files. Is there a setting I need to change inorder for it to go through the other referenced files to get it to work? I can open this in OSGViewer and it will load the whole image without issue from the references. I am also looking at the OSGPoster example submission, as it is similar to what I need to do, but can't seem to get it to function properly. Also, I am fairly new at OSG and graphics programming.

Re: [osg-users] Working without PATH variables
Just to confirm, OSG does appear to look in the current directory. I created a very basic test case. My folder contains the EXE, each of the required OSG dlls, and the one image plugin I am using (bmp). I then have a subdirectory, which I access in code via relative directory structures "media/file.bmp". Thanks for all the help.

[osg-users] Working without PATH variables
Hi guys, I've been spending a few days playing around with OSG in my spare time, and I'm wanting to try to put together a small project using it. I was just wondering, how would I go about creating a project that does -not- use PATH variables to find information? For example, to find the compiled DLLs or to find a media folder under the executable's current directory. Sorry for this being a bit of a newbie question, it just seems like the project relies quiet heavily on these path variables in order to find any files, and I'd prefer not to require people using my software to have to create such.

[osg-users] Units in an IVE File
I am having a little bit of an issue with some of my files. I have a database that is in FLT format. I can load it into my program, and it takes a while, but when I query the height at a given x,y location, I get the proper values. Now, i have taken this file and converted it using the osgconv.exe into an IVE file for better performance. This works well when loading it into my viewer, but when I try and query the height at a given x,y, the values I get back are erratic and not remotely close to what i am looking for. is there some way that the units in the ive could be getting messed up (or does it even have a notion of units) and if not, what do I need to do to make sure the number that I get returned is in Feet?

Re: [osg-users] Issue creating a stand alone DLL
I haven't tried it with the redistributable package, but both machines have VS2005 on them, the only difference is that I did not compile and install OSG on the laptop, which is where it isn't working. This is my first DLL project, and one of the first few I am doing on VS2005, so I am not 100% up to speed with the IDE. I was able to get my DLL to register on the laptop after I copied a bunch of the OSG .DLL's onto it, but when i went to use it in my program, CoCreateInstance was returning an error of 8007007E. I am not sure what this means. Any help is appritiated. The project just going into OSG and retrieds all the z values it intersects with at a given X and Y location.
