[osg-users] Using MFC: Create an Custom Control OSG draws into?
Hey guys, I am trying to create a custom control that behaves similar to osgviewerMFC ( I just want OSG to draw within the control.) I've been trying for about a day to port the code from osgviewerMFC with no success. I get various access violations and other errors. I not extremely familar with MFC, but I used it quite a bit two years ago, so I'm not completely new. However I'm sure my inexperience is contributing to my problems as well. :-* Does anybody know any who has tried this , have any tips and/or have other examples?

[osg-users] [build] Successful build using VS2010?
Has anybody been able to successfully build the latest dev-head in VS2010? I kept getting several fatal LINK errors saying it cannot open input files ex: LINK : fatal error LNK1181: cannot open input file '..\..\lib\Release\osgGA.lib' I'm assuming it's a path error made somewhere in the build scripts. I posted about this a couple of months ago and I couldn't find a fix. I tried searching the forums about this topic but couldn't find anything, are we just out of luck trying to use VS2010 for now?

[osg-users] Anybody interested in a Keyframe Capturer?
Hi there, Not sure if there is similar function already in OSG, but I had the need of being able to capture specific Camera position keyframes so I can use them to create a video. Before this capturer, they way I accomplished this was I enabled the Animation path Recorder, positioned my camera to particular point, waited bout 20 seconds, and then continued to my next keyframe. When I was done, I then went to animation.path file and picked out the keyframes that had repeated several times (because i waited for about 20 seconds), I then modified the timings of these keyframes to get the desired flyover speed. I later smoothed the flyover by importing the points into Matlab and used cubic splines to create a keyframe for every single frame. This process took awhile, and was quite annoying having to sift through unwanted keyframes generated by the animation path recorder. So I created my own Handler called "KeyframeCapturerHandler" that acts almost exactly as "RecordCameraPathHandler", infact most of the code was copied from it. Instead of capturing a keyframe at a timed interval, I only capture a keyframe when I'm ready and press a key. So far, it has done exactly what I needed it to do and has saved me time and frustration. I still have to do my interpolation step, but capturing the inital keyframes is much easier. Does this sound like a useful feature that any of you would want to use? Is there already a way to do this without my handler?

[osg-users] Header files with no file type? (no .h)
Sorry if this seems like a noob question, but why do all of the header files in the codebase not have a '.h' filetype? The reason I ask is because it seems that Visual Studio won't highlight any syntax, or provide any of its features while viewing these header files (probably because they don't have a .h associated to it). Is there a way to have VS highlight syntax in these header files that aren't a .h filetype?

Re: [osg-users] [build] Install problem with OSG 2.8.3
yeah, I misread the version number, but I'm pretty sure its a problem with VS2010. When VS2010 builds the solution, the binaries are placed in bin/release directory... however when I use VS2008, the binaries are placed directly in the bin directory, thus the install script not having any problems. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26925#26925 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

why is this happening in the first place?

However, plugins like txp are rather daunting. Perhaps there should be an enforcement of better commenting standards on submitted code. This might reduce the load of questions being asked by the community as they can understand the code better and increase the amount of users who can answer them effectively. Obviously the tricky part is how much better is "better" and what is "good enough?" That can be another discussion. Also, if the user/developer base is more informed of the codebase, you can also have more people who can process submissions Another question arises, how do we better comment/document the current code base we have now? Well that can be up to the community, you can let it be known that OSG is currently looking to improve its documentation and users who find themselves stepping through code to understand various sections, to take the time (time they are already spending walking through and tracing code) and add comments where needed (preferably the parts that confused them). I know for myself, when I was trying to learn some parts of the code, thought that some parts could have been documented better. The OSG quickstart guide was very helpful in my understanding of OSG. These ideas may be logical, but I'm not sure on the practicality of it all. This is my first open source project and biggest project that I have worked with to date, so I may be out of my league and for that I apologize. :P Good luck with your investigation :) Nick -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=24659#24659 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Creating a new AnimationPathManipulator.
Ok, i see what you are saying.. The reason I was changed that was because
referenceTime was getting reset back to realtime in the call to viewer.frame()
( more specifically, inside the Viewer::advance() function).
To avoid this, I don't call viewer.frame(), I now have to:
double simTime = 0.0;
while( !viewer.done() )
{
viewer.getFrameStamp()->setReferenceTime(simTime);
viewer.eventTraversal();
viewer.updateTraversal();
viewer.renderingTraversals();
simTime += 1.0;
}

Re: [osg-users] Creating a new AnimationPathManipulator.
Ok, i got the desired effect that I wanted, I just had to make one change. On line 787 in Viewer.cpp (in function osgViewer::Viewer::eventTraversal()) I changed the code from: Code: _eventQueue->frame( getFrameStamp()->getReferenceTime() ); to: Code: _eventQueue->frame( getFrameStamp()->getSimulationTime() ); my output is now: Code: 24.00 25.00 26.00 27.00 28.00 29.00 AnimatonPath completed in 30 seconds, completing 30 frames, average frame rate = 1 While I can get this working for me for now, I highly doubt changing core OSG code is the way to go about this(well at least by myself)... Although, this change *could* be correct since if we are using a simulated time, then an animation path should be based on the simulated time. If the user is not wanting to specify a simulated time, the default behavior is using the USE_REFERENCE_TIME value as a simulated time, which is then caught in osgViewer::Viewer::advance() as a special case and sets the SimulatedTime to ReferenceTime. So then calling SimulatedTime instead of getReferenceTime shouldn't cause problems. (Note that I am basing this off of no testing whatsoever and am purely speculating) Any thoughts?

Re: [osg-users] Creating a new AnimationPathManipulator.
OK so I ended up taking osgviewer application and modified the last line from:
Code:
return viewer.run();
to:
Code:
double simTime = 0.0;
while( !viewer.done() )
{
//fire off the cull and draw traversals of the scene.
viewer.frame(simTime);
printf("%f\n",viewer.getFrameStamp()->getSimulationTime());
simTime+=1.0;
}
I then run my modified osgviewer as so:
Code:
osgviewer -p saved_animation.path demo1.earth
with my saved_animation.path containing(only area of concern are the first
numbers of each line, the rest are coordinates,etc):
Code:
0 -2325407.84602605 -3773744.01822793 4620950.6465483 0.789763463262851
-0.198065735037136 -0.0367132622717805 0.579392589763306
30 -2265729.64421162 -3667179.98272433 4731436.64144345 0.782981051316165
-0.194916972743774 -0.0398361681693882 0.589373503579705
But the animation still takes 30 *realtime* seconds to complete, and does so in
370 frames. here is my output:
Code:
366.00
367.00
368.00
369.00
AnimatonPath completed in 30.0006 seconds, completing 370 frames,
average frame rate = 12.3331
Now with 12fps, I would expect the animation path to complete in 30frames
/12fps = 2.5 seconds, while completing only 30 frames.

[osg-users] Creating a new AnimationPathManipulator.
Hi all, I am thinking of taking the existing AnimationPathManipulator class and tweaking it so that it iterpolates between keyframes with frames, not time. so lets say I have defined two keyframes at 'time 0'@position X and 'time 100' @ position Y, instead of interpolating that in 0 to 100 seconds, I want simply want to interpolate X to Y in 100 frames. The reasoning behind this is that I want to capture flyover video and have reproducibility of my captures. Using the current APM, the captures would be dependent on the FPS performance of my machine and if it varies during capturing, my video will look "off". If I interpolate based on frames, then regaurdless of the fps, all frames will be exactly the same and evenly spaced. Is there already functionality like this in OSG? I haven't fully looked into APM, so it might have this functionality hidden inside it... Thank you!

Re: [osg-users] Pentium 4 ht vs. Core Duo - (My Mundane Observation of the day) Any Ideas?
Hi, The only thing that was really going for P4 is that it can be clocked extremely fast. But the fast clock cycle led to an extremely long pipeline (over 30 stages!). HyperThreading (the technique that simulates two threads running at once) is really only useful in certain situations. Core 2 duo went back to a P3 design (i think), added some current features, and put two cores on a single chip. This architecture is better than P4 by far and is more efficient, which is why you are seeing a high performance degregation when compared to the Core2 duo. I'm taking an advanced computer architecture course this term and we went over these two architectures.

[osg-users] [vpb] What can I do with an ive file?
Hi OSGers, So I just got done creating the Pugent Sound example given from the vpb website. The coloring didn't turn out right, but the elevation map worked. (only the bottom left hand corner is colored with the texture). Now I am left with the .ive file that has a great looking 3D terrain. What i would like to do is to apply my own textures on the 3D terrain on the fly. The texturing would look similar to this: envision.bioe.orst.edu/StudyAreas/Bainbridge/bainbridgeContextMap.jpg I have access to the data represented by map, so I'm assuming I will just need to rasterize it to a texture and then apply it to the terrain. Can I quickly do this interactively(ie not waiting 3hr for it to process)? I would need to use different textures on the fly as the data can change based on the user's input. Also, later requirements request for me to add more detail to the terrain ( such as forests, neighborhoods, cities, water, etc), they want the landscape to be "photo-realistic". I would assume instead of "painting" on colors, I would instead "paint" forests, neighborhoods, rivers, etc.. FYI, I am a complete newbie to OSG(first post!) and hopefully I have not bitten off more than I can chew :?. Is what I'm trying to do feasible( well I'm sure it is, but is it realisticly doable?)
