Re: [osg-users] ref_ptr wrong utilisation ?

If TextureInit is, for example, a singleton that persists for the life of the application, then it's destructor never gets called. However, it only allocates once. If this is the case, then technically speaking it's not a leak, at least not the kind of leak that would impact anyone's application.

Re: [osg-users] setLODScale affecting near far planes?

Do you get the same behavior when viewing your database in osgviewer and hitting the * and / keys? -Paul Hi all, I am getting this rather weird effect when playing with the setLODScale values in my application. I have a large pagedLOD terrain, with near/far planes culling mode

Re: [osg-users] setLODScale affecting near far planes?

Hi all again, Robert: for you last question; yes, I have near/far culling enabled and the near/far setting is compute_near_far_using_bounding_volume. If the near far modification that is taking place should be very small, somehow I am still getting quite significant jumps because

Re: [osg-users] setLODScale affecting near far planes?

FYI, Roland is correct, the OSG just does culling on sides of the frustum by default. OpenGL does no culling, is just does near and far *clipping*. The OSG of course doesn't change this so will do near/far clipping and the only way to switch this off is to disable GL_DEPTH_TEST. Even

Re: [osg-users] 2.6.1 release

You should use the same version as you used with OSG v2.6.0. On Windows, I'm using Mike Weiblen's prebuilt 3rdParty binaries, at svn rev 531. -Paul Hi Paul. I'd like to open this up for testing to anyone willing to help out. Check out 2.6.1 from here:

Re: [osg-users] 2.6.1 release

Sorry if that last email from me appeared a bit curt; I had an appointment and wanted to at least get something off to you before I left my computer. Here's more details... I mentioned I use Mike's prebuilt binaries for Windows. Attached is a batch file from Mike's svn tree that contains the

Re: [osg-users] 2.6.1 release

GenWrapper - no. I've just done a rebuild on OSG 2.6.0 to check, and didn't get a genwrapper error message. I'm trying to reproduce this issue, and here's what I've found so far. In 2.6.1, if I right click on the 'wrappers' target and select 'build', then genwrapper is found and runs

Paul, Will this release include the FLT Export fix for PositionAttitudeTransforms AND the FLT ExportOptions texture path stripping option initialization in the constructor with ReaderWriterOptions passed in? Yes, both of those are included. The other FLT fix we discussed (the
