It works well stand alone, but embedding the viewer in a WinForms form
is likely to be a non-trivial exercise at this point.  I believe one of
the osgDotNet users got it to work, but he had to use the Tao OpenGL
bindings for .NET to set up the graphics contexts.

Re: [osg-users] ??: A simple question from an learner.

2007-08-03 Thread Mike Wittman
Hi Bingli,

 

I suspect you've got "pure" CLR support (/clr:pure) selected in your project 
configuration, which tells the compiler you're only using managed code.  You 
need to have standard CLR support (/clr) selected to compile against the native 
code of OSG.  The setting is in the General section of your project's 
Configuration Properties.

Re: [osg-users] I can't find writeNodeFile in the osgdotnet wrappers

2007-08-14 Thread Mike Wittman
Hi Zachary,

I think I just missed the write* global functions in osgDB.  Those can
be added without much problem.

Regarding Osg.Node.getDescription: it should be possible to support at
least the const version of the corresponding C++ function; I'll have to
take a look to see what's going wrong there.

I created a couple trac tickets to track these issues on the osgDotNet
project site.  If you find anything else that's not a known problem,
could you file the bug there?  I don't want to miss anything in the
shuffle of the mailing list.

Re: [osg-users] osgDotNet : Used from C#

2007-08-16 Thread Mike Wittman
Hi Christophe,

 

Thanks for your comments on osgDotNet.  

 

Regarding (A1): you'll need to build the Debug osgDotNet assemblies and use 
them with the Debug OSG DLLs.  If you do that you should be able to see native 
OSG state when you've stepped into the osgDotNet and OSG code.  Unfortunately 
you can't see the native state when stepping through the managed code.  Also, 
debugging across the managed/unmanaged boundary only works for 32 bit code, not 
64 bit, due to a CLR/Visual Studio limitation.

 

(B): IMO weaknesses in osgDotNet or osgIntrospection should be addressed in 
their respective codebases rather than as patches to the core OSG.  Burdening 
Robert with unnecessary work due to this project would not be a good way to 
ensure his continued support. :)

 

Just patching your local copy of OSG can be done, but I'd advise against it 
because it's fragile and contravenes the project goal of maintaining a similar 
API between C# and C++.


 

For public attributes, support just needs to be added to osgDotNet to handle 
these.  Some work has been done towards this end, but it's not there yet.

 

Currently there is a rudimentary mechanism in the code generator to add custom 
support code to classes.  In the absence of support for operator functions in 
osgIntrospection, this could be used to handle the NodeCallback issue, 
including virtual calls from C++ to C#.

Subject: [osg-users] osgDotNet : Used from C#

 

The osgIntrospection+osgWrapper and osgDotNet-generator work very well 
together. (See 
http://www.openscenegraph.org/projects/osgDotNet/wiki/GettingStartedWithTheWrappersGenerator).
 

Thanks to the osg team for such taht interesting release ! 

After a bunch of tests, the generated Managed C++ DLLs work perfeclty well 
referenced in a C# solution and "porting" a native osg program to osgDotNet in 
C# is quick since names of classes, methods and stay the same through the 
osgDotNet API.

 

Yet, two problems remain for the programmer that wants to build an interactive 
application in .NET (C# in my case) :

(A) Debugger use. As is, it seems impossible to examine the unmanaged C++ 
content (native osg) carried by osgDotNet instances, even if the "Enable 
unmanaged code debugging" option is set active in the Debug properties of the 
projects.

(B) Update vs Draw. Some fundamental methods of classes (ie 
Osg.NodeCallback.operator()()) aren't wrapped. Also, some classes interface 
become very static in osgDotNet compared to native osg because their 
fundamental members were set public and accessed directly in the native API 
(limitation of osgIntrospection, as explained among the last points of 
http://www.openscenegraph.org/projects/osgDotNet/wiki/DifferencesWithNativeAPI 
). An example is OsgSim.LightPoint and _on member.

 

 

Regarding (A)...

The Generator builds an osgDotNet solution that only links with the release 
versions of the native osg libraries (which stays in phase with the fact that 
using osgDotNet dlls, you have to copy aside your osg.NET dlls - on set in the 
Windows Path - release versions of the native osg Dlls as explained at 
http://www.openscenegraph.org/projects/osgDotNet/wiki/GettingStartedWithTheWrappers).
 

 Is that the main explanation of (A), or is there something else ?

 Can we modify the osgDotNet solution produced by the generator 
to link with debug version of the native osf librairies to solve the (A) 
problem ?

 

Regarding (B)... 

Solving the issue with for example the lightpoint is easy : I only have to make 
a few accessor add in (native) osgSim as well as in osgWrappers/osgSim and 
rebuild OpenSceneGraph. In other words a quickly coded litlle patch on the osg 
native release. 

 There, just one question : is it useful to submit to the OSG 
community those patches as we introduce them or will the release to com (2.2.0) 
include those or an osgIntrospection improvement that will render this obsolete 
?

Concerning the more important NodeCallback issue, it may be embarassing : it is 
a callback method called from the native osg internals that have to impact the 
overriden method coded in C#.

Did you rebuild the osgWrappers/osgSim DLL?  If that builds without
error the osgDotNet generator should see your additions.  Note that the
build of the osgWrappers DLLs is not enabled in the default CMake
configuration; you need to turn on BUILD_OSG_WRAPPERS.

 

If you've got a Linux box handy, genwrapper is pretty trivial to get
started with.  Just make sure you've got boost, doxygen, and libxml2
packages installed, and the follow the example at
http://www.openscenegraph.org/projects/osg/wiki/GenWrapper.  On Windows
it's a pain because you need to set up all the dependencies yourself.

Sorry... too many thoughts into too few sentences. :)  Let me try to be
more explicit:

 

Take a look at the custom code items in the GeneratorConfiguration.cpp
file in the osgDotNet generator source.  That mechanism is used to
insert arbitrary code into osgDotNet-generated wrapper classes, so
hand-coded wrapper functions to support NodeCallback::operator() could
be added there.

 

Currently genwrapper/osgIntrospection ignores operator functions, and
adding proper support for them is non-trivial, so this one-off
hand-coded approach is the best way to support them in osgDotNet right
now.

 

Virtual function invocation among wrappers, user-defined subclasses of
wrappers, and native code works in all directions by virtue of the
design of osgDotNet.  This support also extends to hand-coded virtual
function wrappers if their implementations mimic the auto-generated
support code for virtual functions.

It sounds like the generator may be picking up an old or wrong 
osgwrapper_osgSim.dll for some reason.  If you set the environment variable 
OSG_NOTIFY_LEVEL to DEBUG before executing the generator it'll cause the OSG 
DLL loader to tell you exactly which wrapper DLLs are being loaded.

 

Also, the symbols in osgSim.dll are not used for the introspection information; 
all of that is contained in the osgwrapper_osgSim.dll.  In crude ASCII art 
form, the basic information flow looks something like this:

 

 doxygen   

OSG headers ->

Well in fact, I didn't pay attention to the osgwrapper_osgxxx.dlls since I 
thought the input for the Generator was the cpp source files of the wrappers 
and not the built dlls. 

You're perfectly right about the CMake built .sln (make sure to call Rebuild 
Wrapper osgSim and not simply Build, since I left OFF the BUILD_OSG_WRAPPERS in 
CMake), anyway that's what I did yesterday, and had that DLL rebuilt indeed. 

I don't understay what goes wrong since I see - using Depends.exe for example - 
my additions' symbols inside the native osgSim.dll. The OPENSCENEGRAPH_X86_DIR

Ok, that soothe my mind on that !! 

Knowing that, solving the operator wrapping problem becomes the right point to 
work on..

I see, you're talking about the getCustomCode() thing. 

I may try something there... if I get to something clean enough I may submit it 
to the team.

file to complete the support.  Take a look at, for example, the generated 
wrapper code for osg::Group::replaceChild for a model of what the code should 
look like.

 

The GeneratedCode.uml file in the doc directory has some class and sequence 
diagrams covering the design of the virtual function support if you'd like more 
background.  It can be viewed with StarUML.

Subject: [osg-users] osgDotNet : Used from C#

 

Continuing on that second issue (still trying to uderstand the first one) :

 

> Virtual function invocation among wrappers, user-defined subclasses of

Well I managed to add the following code in osgDotNet's Osg's NodeCallback.cpp :

void NodeCallback::operator()(Osg::Node ^ node, Osg::NodeVisitor ^ nv)
{
___vtnp(this)->operator()(___vtnp(node), ___vtnp(nv));
}

and of course this one in osgDotNet's Osg's NodeCallback.h :

virtual void operator()(Osg::Node ^ node, Osg::NodeVisitor ^ nv);

 

 

Everything builds right and I can see the following addition : 
Osg.NodeCallback.op_FunctionCall(Osg.Node node, Osg.NodeVisitor nv)  from my C# 
application which allows me to write my UpdateCB inherited from 
Osg.NodeCallback, but in real time my UpdateCB.op_FunctionCall(...) isn't 
called. 

 

In fact, I don't see the mecanics that'd allow in the first place the osgDotNet 
NodeCallback.operator()() to be called when native NodeCallback.operator()() 
is...

Are you sure this use case works ?

 

Sorry for bothering with that, but I don't see any other way to manage to do 
scenegraph update without having it colliding with cull and draw (at least in 
osg >= 2.0.0).

Hi Robert,

With 2.1.6 I'm seeing an unresolved symbol error in the osgTerrain
wrapper library using VS 2005.  osgTerrain::CompositeLayer::clear is
declared in the header but never defined.

Re: [osg-users] Changing Renderer destructor from private to protected

2007-08-24 Thread Mike Wittman
Hi Jason,

 

A protected destructor is a valid solution if Robert's OK with it.  The
only other option I'm aware of is to suppress wrapper generation for
that type in the configuration for the code generator.
osgTerrain::GeometryTechnique is suppressed for that reason, for
example.

Hi Robert and Mike Wittman,

 

I tried to build the osgDotNet wrappers last night against the latest
SVN and could compile them wrappers because osgDotNet subclasses
Renderer and tries to access its destructor, which is private.  I
modified Renderer to have a protected destructor and things built fine. 

 

Any issue with changing the access level of Renderer's destructor from
private to public?

 

Thanks,

Re: [osg-users] Flipping the normals

2007-08-28 Thread Mike Wittman
Hi Mike,

 

Take a look at OpenGL's two-sided lighting support via
glLightModel/GL_LIGHT_MODEL_TWO_SIDE (and exposed in OSG with
osg::LightModel).  I think that's the more elegant solution your looking
for.

Subject: [osg-users] Flipping the normals

 

Hello,
I've a relatively easy task to accomplish, that is to render a mesh both
from inside and outside. 
To do this i put the mesh under two different Geodes, in one i set the
front face to "clock wise" on the other I set the front face to "counter
clock wise" turning on the backface culling (or putting the object into
a single Geode turning off the backface culling). The problem is that in
one case (when I render the "interior" of the mesh) the polygons are not
lit since the normals are (of course) not flipped, that is they remain
oriented "outward". 
My question is: how can I flip the normals? should I create two distinct
meshes, one with the original normals and the other with inverted
normals (modifying manually the normal buffers, and doubling the memory
usage) or there is a more elegant way to do that, for example a
node/state like GL_PLEASE_FLIP_MY_NORMALS that can take care of this
task automatically? 
Cheers,
Mike

Re: [osg-users] Time to default to using OSG_MSVC_VERSIONED_DLL?

2007-09-07 Thread Mike Wittman
Hi Robert,

If OSG_MSVC_VERSIONED_DLL becomes the standard, it would be very useful
to add an option in osgversion to spit out the OSG SOVERSION (and one
for OpenThreads, if different).  Otherwise scripted manipulation of OSG
binaries across releases will be difficult to do with precision.

I'll see if I can't take a crack at this.

This is fixed in osgDotNet SVN -- I have successfully built it against
2.1.9.  Beware though that there are some unresolved runtime stability
issues with regard to object destruction and the garbage collector with
the OSG 2.1.x versions.  If you're not doing anything terribly complex
though you may not observe the problem.

Re: [osg-users] osgdotnet Generator

Hi Wolfgang,

That's almost certainly the runtime stability issue I mentioned.  Something 
changed post OSG 2.0 that osgDotNet doesn't like, but I haven't tracked down 
exactly what it is yet.  I'd recommend staying with the 2.0 wrappers until this 
is fixed, if that release works for you.

Re: [osg-users] Use of osgDotNet Wrappers

2007-09-18 Thread Mike Wittman
Hi Jason and Christophe,

 

Operator overloading is a known deficiency.  But it's unlikely to be resolved 
in an automated fashion in the near future due to extensive changes necessary 
in osgIntrospection.

 

The solution for now is ad-hoc support on a per-type basis, added to the 
generator.  If you know how to patch the generated files to support the 
operators you're using, then it's only a small step to add that same 
information to the generator configuration so that it is added to the generated 
code automatically in the future.  Just modify GeneratorConfiguration.cpp, send 
a patch, and I can integrate it into osgDotNet SVN.

 

On the general question of osgDotNet use, I'm actually only using the wrappers 
intermittently at this point due to some changes in project direction.  But I 
still intend to support osgDotNet releases on top of stable OSG releases in the 
future.

Subject: [osg-users] Use of osgDotNet Wrappers

 

Hi everyone,

I'm just curious to see how many people are currently using or are 
interested in using the new osgDotNet wrappers with their applications?  My 
company is currently using our own custom .NET wrappers for OSG but we're 
interested in transitioning to Mike's wrappers and I wanted to get a feel for 
the number of people in the OSG community that would be using the new osgDotNet 
wrappers. 

Thanks!

Jason

Hi Christophe,

 

Public variable support is definitely simpler than general operator
support, and I'm working on an implementation.  Currently it's mostly
complete; it's just the C++/CLI code generation for the property
functions that remains to be done...  I can't predict when it'll be
finished though as I don't have much time to devote to osgDotNet in the
near future.

The non wrapping of public variables is an issue too, that necessitates
modification by hand too (for dynamic use of LightPoints for example).

Is that evolution (maybe less tricky than the operator issue) planned
for the future ?

Hi Jason and Christophe,

 

Operator overloading is a known deficiency.  But it's unlikely
to be resolved in an automated fashion in the near future due to
extensive changes necessary in osgIntrospection.

 

The solution for now is ad-hoc support on a per-type basis,
added to the generator.  If you know how to patch the generated files to
support the operators you're using, then it's only a small step to add
that same information to the generator configuration so that it is added
to the generated code automatically in the future.  Just modify
GeneratorConfiguration.cpp, send a patch, and I can integrate it into
osgDotNet SVN.

 

On the general question of osgDotNet use, I'm actually only
using the wrappers intermittently at this point due to some changes in
project direction.  But I still intend to support osgDotNet releases on
top of stable OSG releases in the future.

Re: [osg-users] Use of osgDotNet Wrappers

2007-09-19 Thread Mike Wittman
Hi Zachary,

I can tell you the wrappers are fairly complete currently: about 90-95% of the 
C++ API is covered.  You'll just have to judge whether any the remaining 5-10% 
is must-have functionality for you.  The main missing areas are:

1. public variable support
2. pure-STL types support
3. operator function support

Currently, #1 is being worked and is not too far from being in place.  #2 is 
unlikely to be added soon.  #3 is unlikely to be supported generally anytime 
soon, but specific instances can be supported fairly easily.

Regarding ongoing maintenance, my intention is to gradually improve the 
coverage, while supporting wrappers for stable OSG releases from 2.0 on.  I 
have limited time to devote to osgDotNet, but the code is always there if you 
run into a problem.

Hi Jason,

 

I think I saw the same thing due to the rearranging of DLL locations and
names in the Windows build.  I made some changes to try to handle that,
but they may be wrong or incomplete.  You might try setting
OSG_NOTIFY_LEVEL to DEBUG before running the generator to see if the OSG

I'm still working off 2.1.9, so I can't reproduce this at the moment.

Re: [osg-users] Error with current osgDotNet wrapper generators

2007-09-19 Thread Mike Wittman
I think the DeleteHandler changes went in pre-2.1.9, and I'm still
seeing issues with that release.  So there has to be something else
going on.

 

I've been able to pretty reliably reproduce the problem by creating a
small scenegraph and visiting it with a NodeVisitor subclass, all the
while running continuous GCs on a background thread.  This is on a dual
core box, which may or may not be relevant.  My best guess is there's
some kind of thread safety problem related to reference counting or
lifetime management that wasn't there in 2.0.

There's logic in the generator to handle the bin vs. plugins directory
change, and it's been working fine for me with 2.1.9.  It's gated in the
preprocessor based on OSG version, so it could be that you're picking up
old OSG headers when building the generator.  The logic in question is
in AugmentedTypesFactory::loadIntrospectionLibraries; I'd try dumping
preprocessed source and/or stepping through in the debugger to see

Hi Jason,

 

I don't see anything special about the osg::Texture::allocateMipmap
function interface that should cause that problem, and it sounds like
other pure virtual Texture functions are handled appropriately.
Possibly it could be due to a mismatch in OSG versions between headers
and wrapper DLLs.  I'll look into it when I have the chance.

I'll try to take a look at it this evening if I get a chance.  The only
issue I had with building the wrappers after I copied the dlls to the

Subject: [osg-users] osgDotNet : Nodes adding to scene graph outside 
main()function scope

 

Hi everyone,

 

I don't know if I was very clear in my last post. My problem is to implement in 
C# small sfx in nodes in the scenegraph...

 

The fact is that as soon as the Osg.Node (in the example the _root 
Osg.PositionAttitudeTransform) that is added to the scene is enterily monitored 
by a C# class (and not statically or locally defined in the main loop 
function), there seems to occur destruction on that Node being nonetheless 
regular in term of OSG reference count (the _root is held by the MySfxInstance, 
added to the sceneGraph, and therefore its ref count is 1).

 

Of course, in osgDotNet (managed code), ref_ptr and 
osg::Referenced::ref()/unref() aren't ported.

I'm assuming that reference count managing is done according CLR behaviour (as 
long as a reference on your instance is held by someone, the CLR doesn't invoke 
Dispose on that instance). 

 

Am I missing something obvious ?

Am I the only one using osgDotNet having this problem ?

Hi Christophe,

 

The dependency on camera position is an interesting and potentially important 
insight.  There may be some location-related conditional behavior within the 
native code that osgDotNet is not handling properly.

 

Can you tell me generally what is contained in the scene graphs of the models 
that you are loading?  That may have some bearing on the problem.

Hi Mike,

 

Thanks for telling me the same kind of thing was already reported ! 

I understand passin in OSG 2.1.12 would do no good.

 

Thanks also for confirming the OSG reference count management being done by the 
wrapper layer in a .NET Managed-fashion...

 

It's quite hard to find the root cause indeed, since it seems to depend on 
independant factor, like where the camera is -initially- positionned : I only 
get the problem when letting osgViewer set it away from the scene (no 
osgViewer.getCameraManipulator().setHomePosition() call in my mainloop). 
There's something about an intersect visitor apparently (a culling pass ?).

One could think it's only where the AccessViolation first occur. I'm not sure : 
if I initialize the camera close to the scene geometry, not only does my 
AccessViolation vanish, but I don't have the OSG Notice warning about a 
possible problem anymore either. That whether I leave space between my point of 
the scene and scene geometry through manipulator's behaviour afterwards in the 
run time of my application...

 

Anyway, if anyone happen to lock the root cause, please don't hesitate to post !

2007-09-25 Thread Mike Wittman
Hi Jason,

 

I expect this is a pretty deep problem related to the way reference counting is 
handled by osgDotNet.  I'd recommend reviewing the RefCount Deletion Statechart 
diagram in the GeneratedCode.uml file, which gives insight into the (intended) 
reference counting strategy.  Also I found the book CLR via C# extremely 
helpful in understanding how the CLR GC works.

 

I do intend to look into this more when I have the time, but I'm not sure how 
soon that will happen.  If you figure it out in the mean time I'll be happy to 
accept a patch. :)

Hi Mike,

I tried to do some debugging with regards to the PAT issue I added and it has 
something to do with the finalizer being run a NodeVisitor object, but that's 
about as far as I got.  I couldn't understand why it would be an issue for 
nodes containing particle systems, but other nodes are fine.  I think it has 
something to do with the adapter pattern being used that allows a user to 
subclass Nodes in C#, but I haven't gotten any further.

Hi Mike,

 

Thanks for telling me the same kind of thing was already reported ! 

I understand passin in OSG 2.1.12 would do no good.

 

Thanks also for confirming the OSG reference count management being done by the 
wrapper layer in a .NET Managed-fashion...

 

It's quite hard to find the root cause indeed, since it seems to depend on 
independant factor, like where the camera is -initially- positionned : I only 
get the problem when letting osgViewer set it away from the scene (no 
osgViewer.getCameraManipulator().setHomePosition() call in my mainloop). 
There's something about an intersect visitor apparently (a culling pass ?).

One could think it's only where the AccessViolation first occur. I'm not sure : 
if I initialize the camera close to the scene geometry, not only does my 
AccessViolation vanish, but I don't have the OSG Notice warning about a 
possible problem anymore either. That whether I leave space between my point of 
the scene and scene geometry through manipulator's behaviour afterwards in the 
run time of my application...

 

Anyway, if anyone happen to lock the root cause, please don't hesitate to post !

Hi Christophe,

 

This sounds like a bug that Jason reported where a particle system 
under a PAT node gives the same symptoms - 
http://www.openscenegraph.org/projects/osgDotNet/ticket/1.  I've dug into that 
problem some, but only enough to know that it will take quite a bit more time 
to track down the root cause.

 

You're correct about the reference count management; it's intended to 
be completely handled by the wrappers and transparent to the C# user.  
Obviously something is going wrong in this particular case.

OSG can definitely be used with WinForms.  It sounds like you're running
into some project configuration issue though.  If you can post your
error messages we might be able to provide better help.
