[osg-users] osgText + NVidia driver bug fix checked in

Hi All, Thanks to Sherman Wilcox the cause of the crash in osgText looks to have been tracked down to a problem with some NVidia drivers handling subloading of 0 sized data that was triggered by spaces in text. While this actually is a legal size but it causes the NVidia driver to crash no less -

Re: [osg-users] (VPB) osgdem not providing terrain heights with --tile-terrain-size --tile-image-size options

Hi Scott, The tile dimensions aren't controlled in size, it's purely done in post dimensions. If you don't need high res heights then just set the --tile-terrain-size to something like 16 and then limit the number of levels provide using -l . Robert. On Fri, Mar 28, 2008 at 10:36 PM, Hulet, Sc

Re: [osg-users] [VPB] Overriding source reprojection requirement in vpbmaster

Hi Glenn, It's correct vpbmaster refuses to do a build if the sources aren't all the same coordinate system as otherwise running osgdem on multiple processes at the same time would cause multiple reprojections on the same data at the same time and an unholy mess. The way to manage the reprojectio

Re: [osg-users] [VPB] Overriding source reprojection requirement in vpbmaster

Robert, I didn't explain myself properly. All my data is indeed reprojected in advance. The issue is that vpbmaster just *thinks* the data needs reprojection -- I suspect the fault lies with the ECW plugin -- and so I'd like to override the check and tell vpbmaster to forge ahead anyway and treat

Re: [osg-users] [VPB] Overriding source reprojection requirement in vpbmaster

Hi Glenn, If VPB is reading the coordinate systems for the source and the required target coordinate system and not matching them it'll reproject, this matching does rely upon the WTK strings to be equal, so perhaps this is where the divergance is occurring. I don't have any ECW data or plugin av

Re: [osg-users] [VPB] Overriding source reprojection requirement in vpbmaster

Robert, Exactly: it is quite possible for different WKT strings to represent the same CS -- I don't think there is a canonical WKT representation per se. I have the same challenge in osgGIS. ECW=>GeoTIFF would work but ... unfortunately most of my ECW's are just plain large -- in one case I have

[osg-users] Annexing the old OpenSceneGraph/XCode directory, moving to using just CMake

Hi All, This time last year CMake's support for XCode wasn't up to OSX users requirements, so reluctantly I agreed to temporarily allow the old XCode directory to be maintained while CMake gained full XCode support. With OSG-2.4 on the near horizon I'd now like to review the situation but since

Hi Jason -- Thanks for taking this code for a test drive. FLT doesn't support POINTS primitives, so those warnings are just FYI that you're exporting a scene graph that is ill-suited for export to FLT. The only comparable FLT entity would be a light point, but if you want light points, then you s

Hi Paul, The case when the new flt load was complaining about GL_POINTS was on a dataset that I first loaded from .flt then converted to .ive and then from .ive to .flt. I don't know if it was light points in the original .flt file, or how the point got in there, but somehow they did. Robert. O

Re: [osg-users] ANN: FLT export

Looks like the importer interprets DrawMode OMNIDIRECTIONAL_LIGHT as a POINTS primitive. I can support the inverse mapping in my exporter to stifle the "GL_POINTS not supported" warning. I'll add this to my to-do list. -Paul > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[E
