Re: [osg-users] OpenSceneGraph-TrainingMaterials - SVN problem - missing files?
Hi Declic, Thanks for the suggestion but I am using the new SVN server. I have upgraded to TortoiseSVN 1.8 and still have errors although the error message is different - and perhaps gives a better indication of the cause. All the other files in the TrainingMaterials repository download OK so it seems to be a repeatable issue for both versions of the TortoiseSVN client. The URL in the PROPFIND request error is incorrect despite the update using the new SVN repository. Could this be the source of the error? I recreated my local copies by performing a checkout from the TortoiseSVN repo-browser using the new SVN repository URL. It would be interesting to know whether anyone else sees the same issue with an SVN update of these directories or whether it is purely a feature of my Windows 7 desktop environment.

There's a node at the top, and after a certain delta time the child node that's on is turned off, and the next child is turned on. If all the child nodes are turned on we get a nice solid 60 FPS. Spin it around, move it here and there, no change in FPS. So the prolem isn't just too much data to fit on the card. When we animate with a delta time of .05 seconds we also get a nice smooth animation at 60 FPS. But, here's where things get weird, if we use a delta time of 1 second we get a sudden and very drastic drop in frame rate. The size of the drop seems to be related to the amount of data getting turned on and off. Same thing if you manually single step the animation.

Re: [osg-users] Help: Using OSG To Build Tiled Display Wall
Martin, The most I have seen is four screens on one (Windows) PC powered by two SLI graphic cards, where each card has two video outputs. To go beyond this is possible with a linux os using remote displays (DISPLAY 0:0 etc) but you don't get something for nothing. The network traffic is high and the resulting graphics are slower as the network reaches saturation even using a UDP connection. I have no idea what sort of workload it places on your host (or master) compputer if it does all the graphics processing and pushes commands on to your network, but I would suggest again that this is not the way to go. If it was, all the various IG protocols such as CIGI (see previous posting on this thread) would never have been invented. So you have reached that crucial decision point - limit yourself to 4 displays assuming it all works or write a CIGI (for instance) interface for each node type (host and IG) and attach as many displays as you like.

Has anyone here used heavy-duty graphics hardware to feed four or more views from one machine? What hardware setup do you use, and are you able to render reasonably complex scenes?

Re: [osg-users] Multiple Shaders Performance Question
Paul, Running at 120Hz is rather extreme since the human eye can't really appreciate a frame rate higher than 60Hz - OK monitors are normally rated at approx 75Hz to be flicker free, but 60Hz is the norm. With this in mind, you might be able to hide this missed frame by simply reducing your frame rate.

Re: [osg-users] Packaging distribution under Windows
My 2p worth... Since you are considering only a MSVS environment, it looks far more professional to have something like InstallShield. Creating it would seem to be a relatively trivial task (when I watched someone else create one using a VS 2003 InstallShield wizard in about 15 seconds). The only fly in the ointment is deciding on a version that supports VS 7 (2003), 8 (2005) and 9 (2008). As to online and offline installers, I would go for offline everytime because I have worked on simulator sites that will never be connected to the internet. It also means that come the fateful day when the hard disk dies, the complete install is available from a local security backup rather than relying on a hosting website to still be holding the exact version required to restore the system.

Re: [osg-users] Problem with deletion ofDrawableDrawWithDepthShadowComparisonOffCallback
Roger, Any chance you are mixing debug and release dlls? This is a typical debug/release memory management problem, when memory allocated by one dll (using say debug memory management) is deallocated by another dll (built with release memory management). The only solution (and it sort of feels right anyhow) is always let the dll that allocates memory also be responsible for deallocating the memory. That way, there is never a conflict with memory management - mind you other issues might then arise, so probably best to ensure that dlls (and the .exe) are built to the same debug or release state.

When the debugging features of osgShadow are activated by calling setDebugDraw(true). I get a crash when cleaning up my scene. This crash occurs when the destructor of DrawableDrawWithDepthShadowComparisonOffCallback is called. It appears that the 'this' pointer is off by a few (16) bytes by the time the compiler generated destructor is called. I suspect this is a compiler issue with Microsoft VC8.1. Tracing shows that the this pointer starts off OK and the right things are being done to handle the virtual destructor but when the chain of destructor calls gets thunked across into the osgShadow DLL the wrong offset is applied to get from the base virtual destructor this pointer (~osg::Referenced) to the correct derived class this pointer at this point. So has anyone else come across this, or got any ideas whether it is fixable. This might finally force me to move to VC9, a task I am not looking forward to.

Re: [osg-users] [osg-submissions] Matrixf multiply Optimization
As I understand it, the the pragma alignment only applies to predefined
objects and data.
Dynamically allocated objects are created at the mercy of the memory
allocator (via new) which uses byte alignment, as it does not know anything
about pragma definitions.
The only approach is to dynamically create data with extra padding, and then
do some alignment coding, something like:
char* pBuffer = new char[ (200 * sizeof(int32)) + sizeof(int64) ];
int32* p = new (pBuffer) int32[ 200 ];
and then later
delete [] pBuffer; // DO NOT delete p
pBuffer = 0;
p = 0;
instead of the simpler but unaligned
int32* p = new int32[ 200 ];
Youw will have to experiment the actual code required, as I am not too
certain, and my brain is still in bed.

what would be cool is for others to code review the work I've checked in
thus far. If I recall the FFmpeg community has found a way to use
intrinsics in a way that is platform independent, once I get the win32
version polished I may research that.
For anyone interested the C version of the matrix multiply uses 64
multiplies and adds, while the SSE version uses only 16 of each.
In regards to going in and out of SSE I tried this:
union
{
struct
{
__m128 _R0,_R1,_R2,_R3;
};
value_type _mat[4][4];
}
And this works as it forces the array to be 16 byte aligned
implicitly...
unfortunately I ran into problems where some code was using the matrix
in a
vector would throw compiler errors saying it can't align it. (I may
revisit
that case and see why that is)
What I am hoping will happen is that this new code will work out, and we
can
gradually transition some of the most used pieces to take advantage of
the
instruction set. (platform independent of course).

Re: [osg-users] Borland Builder C++ 5.0 compiler support?
Why use BB5? OSG compiles with the free Visual Studio 2008 Express, which just needs to be downloaded from a Microsoft website. VS WinForms is based on BB5 so you would not feel so out of your depth. Only with difficulty will you get OSG to build with VS6, and I suspect it will be even harder with BB5. Is it even worth the effort, when you will probably spend more time trying to get OSG to build with BB5 than developing your application? BB5 is quite old and not compatible with Vista (like VS6). There may also be isues with templates.

[osg-users] Suggestions for a dynamic map
I have been challenged to design an active map display (on Windows). My first thought was to consider something based on the combined osgPick and osgMFC examples, but I wondered whether anyone could suggest something better or an existing open source solution that could be adapted. Design points Map returns the current mouse pointer in metre offsets from map origin. Use origin offsets to return culture data (building, road, river, etc). Cars, traffic lights, etc can be dynamically drawn on top of the map. Map can be dynamically modified by adding roadworks. Map projection must be orthographic. Zoom in and out without pixel blockiness (hence a 3D solution) Scroll the map within its window. Easy construction of the map data/models from existing 3D terrain.

Re: [osg-users] OpenFlight Continuation Record support
Continuation records are great when writing out FLT files but a * when
reading them back in - I had to abandon upgrading some proprietary FLT
reader code because it required a complete rewrite of the FLT file decoder
just to support this one new record type.
The FLT file record structure requires every record to include a known
length not exceeding 1024 bytes, so all the decoder had to do was read the
correct number of bytes from the file into a 1024 byte buffer and then start
processing the record. The existing FLT record structure was retained with
no hint to give advance warning the current record has a following
continuation record.
The only way I saw to support this record type was to strip out the entire
file reading mechanism and craft/hack/jam in a new layer that assembled
internal records from one or more FLT file records, and then sent each
internal record into the decoder core. Unfortunately this broke the entire
design which was based on a long winded while( !eof() ) { readrecord();
processrecord() } architecture.

[osg-users] SVN XCode repositoryhas filename issue
This is an academic issue for me, but I thought I'd just pass it along. Having downloaded the entire OSG repository (using the Tortoise SVN tool) onto my home WinXP system, the tool hit a problem when it reached one of the Xcode projects under the Tags (tagged releases) repository. I think this was either the osgProducer_OpenSceneGraph_BranchPoint or Producer_OpenSceneGraph_BranchPoint release, but I can't remember which - it may have been another. Anyhow, SVN gets itself confused because it downloads a filename in one case and then gets asked to download the same filename with some letters in the alternative (upper/ lower) case. This will work ok on case sensitive systems (ie Linux and Apple) but not on case insensitive Windows, where both filenames resolve to the same filename. The result is that Tortoise SVN gives up reporting errors, because it can't create the second file and it leaves things locked. Obviously the lock issue is down to Tortoise, but the filename issue may require resolution, or perhaps this email appearing in the archives may suffice. I'm a WinXP user but have just started a Linux project so get to see the best and worst of both (let battle commence!!!)
