Is that essentially the change that you were referring to? It's the correct thread. The fix isn't and will probably cause other problems (jitter in some newer view modes, IIRC), but as long as it works for you, all is well. :-) m. I have run into what might be different issue...and might be what you are talking about. With playback data the ground slightly jumps back and forth. It looks almost like a vibration. It seems to happen with all of the views. At first I thought that it had to do with how smooth my Lat/Long data was, so I tried fixing that. But it didn't help. So I finally just did a recording of a simple takeoff at high frequency, with everything at the defaults: fgfs --generic=file,out,32,/Users/dersh/Documents/Cases/587\ Animation/DFDR\ data/test_out.csv,playback and then did a playback: fgfs --generic=file,in,32,/Users/dersh/Documents/Cases/587\ Animation/DFDR\ data/test_out.csv,playback --fdm=null and I get this jitter of the ground back and forth on playback. It is not much (perhaps a couple of feet back and forth). I started to wonder if it might be that the code that reads in the lat/long is not reading in enough significant digits? Internally clearly there are enough because it looks smooth when I am recording. Is there some rounding, or reading in as float instead of a double? Any ideas on this one? Is it the same bug that was fixed in CVS? I have not yet tried to rebuild from CVS since Alex's suggestion to change the order of: globals-get_viewmgr()-update(delta_time_sec); upwards after the line fgUpdateTimeDepCalcs(); seemed to be working for me. But did I hit another issue related to this? Melchior, is this also what you fixed? I am a little nervous about doing a new build because I am using Tat's download/build instructions for a Mac and then I applied Pigeon's patch to capture video. All seems to work, but I am not sure which pieces of that process might break if I do a full CVS update and rebuild. That is also why I have stayed with PLIB. --Adam I spent a while trying to track this down, and finally figured out what is going on. The problem is that generic.cxx can only handle floats, and that is not enough resolution for latitude and longitude, so the last few digits are lost in the conversion. I found a simple solution, that is working for me to be able to read in data correctly: So I changed line 208 of generic.cxx from: _in_message[i].prop-setFloatValue((float)val); to read in a double: _in_message[i].prop-setDoubleValue(val); Now, if I play my data files the aircraft moves in a smooth way. So I figure the more general solution is to add a new type to the generic protocol which is double. That way there is no change to any existing examples. I have attached a few diff files that work for me. playback.xml.diff Description: Binary data generic.hxx.diff Description: Binary data generic.cxx.diff Description: Binary data the only changes are to generic.hxx and generic.cxx to add the new double type. I have also added a diff to playback.xml that make it use doubles for latitude and longitude so that I could test it out. And it worked fine both to record and to playback in a nice smooth way. If there is a better way to submit this patch please let me know. --Adam - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

You need to amend panel.cxx to remove the test in fgPanelVisible for
the current view being the cockpit view:-
bool
fgPanelVisible ()
{
const FGPanel* current = globals-get_current_panel();
if (current == 0)

return false;
// if (globals-get_viewmgr()-get_current() != 0)

You'd use an animated texture, which is basically a series of texture frames, if you were rendering a sequence where you want a moving picture in the background - think rendering a 3D scene that includes a TV screen somewhere in shot.

The best solution for you will come down to how you go about the lip-sync - that is, do you synch the footage to the sound or visa versa. If you have to sync the footage to the sound it'll be very tricky because the frame rate of FG varies and you'll have no fixed reference point from which you can trigger things. However, if the sound is a series of discrete samples you can sync the sound to the footage and things become a lot easier.

Dear LeeE, Hmmm not sure what LiVES is? I am just talking with Syd about a way to do this, some other idea's I have had are based around these such concepts! a/ Well if ailerons can be animated maybe the mouth could have moving parts? for example his lower lip could be like a tiny aileron! b/ Looking at Gerry Andersons Thunderbirds puppets he made a moving lower lip, so this might simplify ways of doing it, by having a simple lower lip animation inset into the face.

To keep it short: I tried the ShadowMap, the SoftShadowMap and the ShadowVolume technique. Both ShadowMap techniques produce some visual effects but no shadow. The ShadowVolume technique (that's the technique implemented in the plib version) print some debug messages and after eating all my 4GB of memory, I get a unknown exception in the main loop while still showing the splash screen.

But it is nice to see, that there are also some others working on that! I did get a prototype working, based on Terry Welsh's PSSM implementatioon. The visual quality was not great, but I now understand the problem. I made a decision to go with shadow maps instead of shadow volumes, those being considered most suitable for modern hardware. The existing shadow implementations in OSG aren't really going to work for us. Except for the PSSM implementation, they assume small databases and also small coordinate values. The PSSM code is extremely hairy with lots of bells and whistles and doesn't seem completely debugged. All of the implementations suffer from a critical problem: they install shaders to draw the shadows and assume that their shaders are the only ones used. So, if you ever want to add shaders for other effects, you're out of luck. A more global system for managing effects and shaders for all materials is needed. I've been working on implementing that before returning to the shadows. Tim - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
