Re: [osg-users] Top 10 OSG Debugging Tips
Hi, Actually You have to redirect both stdout and stderr osgviewer cow.osg foo.txt 21 On windows standard way of logging is to use OutputDebugString function that connects application to windows debugging facilities (i.e output window of visual studio). Many libraries print debug messages this way including MFC, WxWidgets and Qt. My intention is to incorporate OSG notifications into GUI applications. For instance I would like to display notifications in a GUI list widget with messages coloured according to notification severity. In Qt you can do this by installing custom message sink with qInstallMsgHandler. In OSG you're stuck with plain std::ostream handle and no severity information. My proposal is to replace stdout and stderr returned by osg::notify with custom stream that uses osg::NotifyHandler as message sink (similar to qInstallMsgHandler in Qt). ... Thank you!

[osg-users] play animation backwards?
Hi, Unfortunately I couldnt figure out how to play a given animation backwards. The animation is part of a model read from an osgt file. Looking at osgAnimation/Animation.cpp it would be straightforward to add an additional switch case to Animation::update() case ONCE_BACKWARDS: t = _originalDuration - t; if (t 0) return false; However, I wonder if there is an obvious way to achieve the same without having to modify the file Animation.cpp ?

Re: [osg-users] ECEF Oriented Compass Implementation
Since you're navigating on a sphere, you always need to calculate the
bearing based off the local up vector of the sphere (ground
stabilized) and not the up vector of the ownship. The reason why your
code works from the birds eye view is because the up vectors between
the two are the same in this case. When you introduce pitch and roll,
the up vector of the ownship diverges from the sphere up vector
which probably explains why your code below no longer works.
Once you calculate the bearing correctly, your compass heading can then
be calculated by using the bearing angle to rotate around the z-axis
(0,0,1).

Subject: [osg-users] ECEF Oriented Compass Implementation
Hi,
I have an ECEF terrain and I want to implement a compass node to show
the true north to the user.
I tried the code below but at some angles it does not work correctly.
When the camera is vertical (birds eye view) to the terrain, it works
perfect but if you rotate the camera (elevation or roll) it does not
show the correct value.
thanks,

Re: [osg-users] play animation backwards?
Did you try decrementing the simulation time in your call to Viewer::frame()? I'm not familiar with osgAnimation internals, but other animations in oSG, such as osg AnimationPath, osgSim animated light points, and osgParticle simulations, are all based on the simulation time. It would be very odd if osgAnimation didn't work the same way. -Paul On 7/2/2012 9:09 AM, Thilo Weigel wrote: Hi, Unfortunately I couldn't figure out how to play a given animation backwards.

One thing I did notice in the code is that you're passing 'const std::string' in some places. For the sake of efficiency these chould be replaced with 'const std::string' to avoid making a copy every time. Same for passing 'osg::Vec', these should always be passed as const-ref unless they are modified or returned. Maybe this is something you could fix and resubmit? Apart from that I'd say it's good to go. Just my $0.02 Cheers, /ulrich On 31/05/12 11:14 , Sukender wrote: And now the patch. It is about .X: - Brand new writer for .x format.

The reader clearly doesn't read 100% of .x files, but handling is way better now.
