Re: [osg-users] Subversion Installation Step-Step manual

Hi, we use ssh tunnels with svnserve for a private repo. It is OK to manage if you don't have too many users. The only port open on the server is then ssh (22). You can use keypairs for auth then. Users must have something to set up the tunnel, ssh (linux), putty (win), ??? mac. jp Adrian Egl

Re: [osg-users] Subversion Installation Step-Step manual

Hi, as far as I know any client can work with this. You point the client at your local end of the tunnel. e.g. svn co svn://localhost/repo jp Adrian Egli wrote: > And how can i check out it? tigris.subversion client for explorer works > with this settings? > > /adegli > &

Re: [osg-users] Rendering to a texture only

Hi, wrt question 1: you could look at Mesa (www.mesa3d.org) and use their OSMesa (off-screen) library. It is a software-only (obviously slow compared to hardware) OpenGL 2.1 implementation and works well with OSG. This will allow you to render to main memory in the PC. jp Williams Steven-ASW0

Re: [osg-users] That why I think the osg math is really wrong

Hi, I'm using v*q a lot, I don't mind the order changing, as long as the compiler would make me fix them all. Can the intent of v*q or q*v be anything other than rotating a vector? If this is the only meaning, I don't see why we can't have both? regards jp Robert Osfield wrote: > On Nov 13, 2

Re: [osg-users] Problem with dll

Hi, where the guide talks about .lib it is about when you want to compile your own programs that use the OSG. I don't use Windows, but it sounds like you just need the .dll files to be either in the PATH like Robert said, or you could just make a directory where you put all the .exe and .dll f

Re: [osg-users] osgText quality

Hi, I've also had cases with characters clipped, sometimes not even on the same edge. There has been a discussion about this quite some time ago, maybe you can find it if you search for my name, and I remember some other people also proposed solutions. What worked for me was to set the resolut

Re: [osg-users] Using osgSim::OverlayNode

Hi all, just to add that I also get clipping with the new modes from certain viewing angles. Sometimes the clipped edges rotate as the view moves and some parts jump in and out (dunno if this makes sense). I've thought about trying to debug it, but I have no idea where to start, the shaders lo

Re: [osg-users] Looking towards 2.4, and what might go into it.

Hi, could we get support for multiple render targets (MRT) integrated into 2.4? I know some people are using hacky patches for this. Some patches have been submitted, but they have to be reworked. I can help with this if needed. regards jp Robert Osfield wrote: > Hi All, > > After a two mont
