Feature wise OSG is now ready for 2.4, so its just build and run testing now. If things looks really good OSG wise then perhaps we could even think about tagging 2.4 in the second half of next week. If not next week then we'll need to wait till mid April as I have on-site training booked in for the 2nd week of April. It'd be kinda nice to have 2.4 done and dusted before I go, but not great sweat if it doesn't happen. VPB-1.0 won't be till the end of April though as I still have a couple more items to complete first, OSG-2.4 also needs to be out first as VPB-1.0 won't compile with OSG-2.2.

Re: [osg-users] MultiThreads in OSG
Hi Renan 2008/5/6 Renan Mendes [EMAIL PROTECTED]: Hi, everyone. I've tried creating another thread in my application using the windows API (CreateThread, etc), but it seems that this thread has become a main thread, here it's probably misuse of multithreading. i.e, my program is not working as a multithreaded application. In my case, this means that I'm not even displaying the OSG default screen - all I have is the prompt display, printing some information I wanted. Does OSG have support for multithreading? yes it is, but only to render the scene. When you have multi camera or multi graphics context, you can render them in multithreaded operations.

with 2.4 first. If you want to start with my spec file it's attached. I did

%description
The OpenSceneGraph is an OpenSource, cross platform graphics toolkit for
the
development of high performance graphics applications such as flight
simulators, games, virtual reality and scientific visualization.
Based around the concept of a SceneGraph, it provides an object oriented
framework on top of OpenGL freeing the developer from implementing and
optimizing low level graphics calls, and provides many additional utilities
for rapid development of graphics applications.

Re: [osg-users] (no subject)
Hi Pecoraro thank to spot the bug please send your submissions on osg-submissions the next time. after review the original code, at line Optimizer.cpp:1561 lod-getNumRanges() is used to know how many iteration will be done in the for loop, and getNumRanges have to be equal to getNumChild, so lod-getChild(i) at line 1563 is not the problem. Perhaps you LOD is not synchronised (num of children and num of range are not equal)i don't know why or how is possible. Anyway, in a case of a PagedLOD, only the code of LOD is used, so not special case for a PagedLOD. correct me if i'm wrong. Cheers David Callu 2008/6/6 Pecoraro, Alexander N [EMAIL PROTECTED]: I think there is a bug in the osgUtil::Optimizer::CombineLODVisitor - at line 1530 of Optimizer.cpp it does a dynamic_cast on and osg::Node* to osg::LOD* and then at line 1563 it calls getChild(i) (even if getNumChildren() == 0) on the dynamically casted LOD node. This works fine when the node is an LOD node, but when it is a PagedLOD node then it causes in invalid access to the _children vector. I attached a screen shot to show what I mean. This situation would only ocurr when a PagedLOD node was a sibling of an LOD node, which is probably why it hasn't been spotted before. Not sure if this is the accepted way to submit a fix, but anyway I made a fix to the Optimizer code (version 2.4) and attached it to the email.

Re: [osg-users] Problem with 2D and 3D text in the same scene
Hi Frank Problem: osgText::Text and osgText::Text3D use the same font file. The first really load the file and obtain an osgText::Font object, the second use the cache created during the first load of the font file, and so obtain an osgText::Font object instead of osgText::Font3D object. To obtain an osgText::Font3D object, osgText::Text3D call osgDB::readObjectFile(...) with an option to specify the plugin we want an osgText::Font3D instead of osgText::Font. Generalised Problem: In osgDB::Registry, loaded file cache is referenced by the name of this file, so if I load a file with some options, and the cache already contain object for this filename, I obtain an object potentially not loaded with my options. Behaviours: Cache management is delegate to osgDB::Registry, but cache coherence (load a file with option then reuse it, deactivate the cache when load a specific file or don't cached the loaded file) is user's responsibility. Text3D case: Delegate the cache coherence of font file in osgText to the user is not a good idea. So to fix this I think to 2 solution: - never use the cache when load a font for a Text3D. Just because to load a Font3D, we use option in osgDB::readObjectFile() - move osgText::Font3D implementation in osgText::Font, suffix ex-Font3D method with 3D in osgText::Font (so osgText::Font3D::getGlyph() become osgText::Font::getGlyph3D() ) And so Text and Text3D use the same osgText::Font object which contain 2D and 3D glyph.

Re: [osg-users] Problem with 2D and 3D text in the same scene
Hi Robert I think merging the osgText::Font and Font3D implementations would be the cleanest approach. I think too ... but ... Another, more hacky approach would be to postfix the font file name by .Text3D or something similar and then have the freetype plugin return Font3D when it detects this. This solution is really smart, it not break the scalability of osgText. I don't know which use can be done with a font except 2D or 3D glyph, but this keep the door open to other thing. osgText::Text3D have to ensure that name of font file is ended by .Text3D and font file cache coherence is not delegate to the user. I have try this solution and work fine. I prepare a submission if you prefer the second solution. Or implement the first one otherwise. As you want. David Robert.

Re: [osg-users] Bug in RenderBin (?)
Hi Paul, Hi Christof
What is smells fishy is the use of proto-className() to identify the
renderBin prototype to remove in removeRenderBinPrototype();
code
void RenderBin::removeRenderBinPrototype(RenderBin* proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
// something wrong there
RenderBinPrototypeList::iterator itr =
list-find(proto-className());
if (itr != list-end()) list-erase(itr);
}
}
/code
proto-className() return always RenderBin because this is the name of the
class :).
Instead, in void RenderBin::removeRenderBinPrototype(RenderBin* proto) we
need something like this
code
void RenderBin::removeRenderBinPrototype(const std::string binName,
RenderBin* proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
RenderBinPrototypeList::iterator itr = list-find(binName);
if (itr != list-end()) list-erase(itr);
}
}
/code
Thought ?

The actual crash occurs later in static object destruction when
s_renderBinPrototypeList is destructed itself. I don't understand enough of
osg to know what's exactly wrong. However, the s_registerDepthSortedBinProxy
doesn't release the object it created and this looks very suspicious to me.
The fact that two different instances of RenderBin get registered under the
same name indeed smells fishy :)

Re: [osg-users] Bug in RenderBin (?)
Hi Robert
What about the case of register two prototype with the same name. There are
any warning message for the user.
I fix this like that
void RenderBin::addRenderBinPrototype(const std::string binName, RenderBin*
proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
RenderBinPrototypeList::iterator itr = list-find(binName);
if (itr != list-end())
osg::notify(osg::WARN) Warning: RenderBinPrototype named
\ binName \ already registered std::endl;
else
(*list)[binName] = proto;
}
}
void RenderBin::removeRenderBinPrototype(const std::string binName,
RenderBin* proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
RenderBinPrototypeList::iterator itr = list-find(binName);
if (itr != list-end())
{
if (itr-second != proto)
osg::notify(osg::WARN) Warning: Registered
RenderBinPrototype named \ binName \ not match the instance
proto std::endl;
else
list-erase(itr);
}
}
}
thought ?

What is smells fishy is the use of proto-className() to identify the

Well spotted David, the addRenderBinPrototype() correctly uses
binName, while the removeRenderBinProtoype() attempts to use the
className() as it's binName. The later is definitely a bug, and one
that is easy to fix...
Instead, in void RenderBin::removeRenderBinPrototype(RenderBin* proto)
we
need something like this
code
void RenderBin::removeRenderBinPrototype(const std::string binName,
RenderBin* proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
RenderBinPrototypeList::iterator itr = list-find(binName);
if (itr != list-end()) list-erase(itr);
}
}
/code
Thought ?
There is no need to use the binName, one just needs to search for the
pointer in the map by hand, and remove it.
I'm just tested the following code and it looks to be working properly :
void RenderBin::removeRenderBinPrototype(RenderBin* proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
for(RenderBinPrototypeList::iterator itr = list-begin();
itr != list-end();
++itr)
{
if (itr-second == proto)
{
list-erase(itr);
return;
}
}
}
}
I've attached the modified file. Christof could you test this and let
me know how you get on. If things look fine I'll check the changes
into svn/trunk and OSG-2.8 branch.
Robert.

I'm probably stating the obvious, but besides Matt changes I guess icon
loading implementation for each of the platforms except windows will be
required too.

Awesome, it worked. The icon I was talking about is the one in the
upper left hand corner of the window. But it also appears in the

alt-tab popup menu.
This is a Windows platform so the solution I came up with is not
platform independent, but I believe I implemented it in the same generic
way that
GraphicsWindow::setWindowName() is done.
In GraphicsWindow (header file, line 121):
/** Set the icons the window uses */
virtual void setWindowIcons(const std::string /*iconPath*/) {
osg::notify(osg::NOTICE)GraphicsWindow::setWindowIcons(..) not
implemented.std::endl; }
/** Set the name of the window */
virtual void setWindowName(const std::string /*name*/) {
osg::notify(osg::NOTICE)GraphicsWindow::setWindowName(..) not
implemented.std::endl; }
In GraphicsWindowWin32 (header file, line 85):
/** Set the icons for the window */
virtual void setWindowIcons(const std::string /*iconPath*/);
/** Set the name of the window */
virtual void setWindowName(const std::string /*name*/);
(and on line 151, the member variables):
HWND_hwnd;
HDC _hdc;
HGLRC _hglrc;
HCURSOR _currentCursor;
HICON _currentIcon;
In GraphicsWindowWin32.cpp (source file, line 959, the constructor):
GraphicsWindowWin32::GraphicsWindowWin32( osg::GraphicsContext::Traits*
traits )
: _hwnd(0),
_hdc(0),
_hglrc(0),
_currentCursor(0),
_currentIcon(0),
(and on line 1006, the destructor):
GraphicsWindowWin32::~GraphicsWindowWin32()
{
if (_currentIcon != NULL)
{
DestroyIcon(_currentIcon);
}
close();
destroyWindow();
}
(and on line 1878, the Windows implementation of the new function):
void GraphicsWindowWin32::setWindowIcons( const std::string iconPath )
{
HINSTANCE hinst = ::GetModuleHandle(NULL);
_currentIcon = ExtractIcon(hinst, iconPath.c_str(), 0 );
if (_currentIcon != NULL)
{
SendMessage(_hwnd, WM_SETICON, ICON_SMALL, (LPARAM)_currentIcon
);
SendMessage(_hwnd, WM_SETICON, ICON_BIG, (LPARAM)_currentIcon );
}
}
void GraphicsWindowWin32::setWindowName( const std::string name )
{
_traits-windowName = name;
SetWindowText(_hwnd, name.c_str());
}
Here is the code from my ::osgViewer application. Names have been
changed
to protect the innocent (haha):
viewer.realize();
osgViewer::Viewer::Windows windows;
viewer.getWindows( windows );
std::string windowName;
windowName.assign( fooViewer );
windows[0]-setWindowName( windowName );
windows[0]-setWindowIcons( barney.ico );
All that is required is that barney.ico exists in the same directory
that
the executable is run from and contains a valid icon. However, I
verified that this code works even if the iconPath parameter contains
full path information. I did a test:
windows[0]-( C:\\WINDOWS\\nvidia icons\\Portal_32x32.ico );
And it worked like a charm. If the file doesn't exist or exists but
doesn't actually contain a valid icon, the viewer doesn't crash. You
just get the same default icon from before.
Thanks for the great hints,

Re: [osg-users] Bug in RenderBin (?)
Hi Christof
Robert prefer search the RenderBin instance that you want to remove instead
of search the name of a render bin.
like this :
void RenderBin::removeRenderBinPrototype(RenderBin* proto)
{
RenderBinPrototypeList* list = renderBinPrototypeList();
if (list proto)
{
for(RenderBinPrototypeList::iterator itr = list-begin();
itr != list-end();
++itr)
{
if (itr-second.get() == proto)
{
list-erase(itr);
return;
}
}
}
}
Can you test this solution ?
David
2009/3/13 Christof Krüger osgfo...@tevs.eu
Changing the removeRenderBinPrototype to use the binName instead of the
classname fixes the crash. For this, you need to also add a member string
variable to the Proxy object in order to remember the binName.

Re: [osg-users] osgText - size is half of font resolution
Hi Sherman,
I download the FontForge http://fontforge.sourceforge.net/ editor on
sourceforge.
When I examine a Glyph of arial.ttf font with a size of 12 :
- A, there are 9 line for the glyph and 3 blank line under.
- a, there are 2 blank line on the top, 7 line for the glyph and 3
blank line under.
- q, there are 2 blank line on the top, 10 line for the glyph.
My conclusion is when you specify a size for a font,
this ensure that all glyph of the font have a height lesser to the specified
size.
But the place of the glyph is for someone largely over the base line ( for
example `),
and for other under the base line, _. So all the height is used by the
font.
Other source:
In Qt documentation, for a given Font, height is equal to ascend of this
Font
(space over the base line) + descend of this Font (space under the base
line)
+ 1 ( for the base line) pixels.
try attached example,
I take your code and adapt it in a main function.
I print text with height equal to the screen height
(1024 for me, modify the SCREEN_SIZE in file
osgtext_sherman2 : l.11 if you need). When the text is
display in fullscreen, you are sure that all text have
a height less or equal to the screen height,
many time the glyph height is half of the screen
height, but for some glyph ( for example the | or $ glyph)
the height is 3/4 of the screen height.

Can someone explain why the code below consistently produces text that
is half the height specified? If I render this text, take a screenshot
and measure the height of the text ABC in a paint program it will
measure up as approximately 64 pixels tall for a character size /
resolution of 128. I change the 128 to 256, the text will then
measures 128 and so on. Always measures half of what I specify. Should
this not render text that is approximately 128 pixels in height? I
understand that the characters won't be exactly the width/height I
specify, but half? Is this a bug or what?

Re: [osg-users] avoid writing some node on osgDB::writeNodeFile
Hi Alexandre You can just copy the Scene Graph structure (osg::Node, osg::Group, ...) and share every other thing (StateSet, Drawable, texture, ...) You can specify which object to share and which to clone with the osg::CopyOp class. HTH David Callu 2008/10/6 amalric alexandre [EMAIL PROTECTED] Hi osg-users, I would have know if it was possible to avoid to write some node in a scene when calling osgDB::writeNodeFile on the current scene. Let's assume I got a group of nodes and I wand to save this group on disk without saving some chosen nodes from the group. But I don't want to modify the group because I need it to stay the same. My first choice was to make a copy from the group, modifying the copy keeping the original and writing the copy. But I think it's a bad choice because I got very big nodes (300Mo and more) and making a copy use more memory.

better to keep examples into the OpenSceneGraph/examples to keep sync with OSG core isn't it ?? 2007/8/25, Robert Osfield [EMAIL PROTECTED]: Where to host the example source... 1) I see three options - zip files attached to the wiki 2) A svn repository for tutorial examples 3) Putting tutorial examples into the OpenSceneGraph/examples as part of the core OSG. Keeping the tutorials separate from the core OSG will require a maintainer for it, any volunteers? Keeping it separate does have an advantage of show how one builds applications outwith the standard OSG distribution.

Re: [osg-users] Eclipse and OSG

# cd OpenSceneGraph
# mkdir release cd release
# cmake ..
you are now ready to only use eclipse. So launch Eclipse.
1) - Eclipse use
E# Menu - File -Switch workspace : choose the directory where
OpenSceneGraph directory is.
E# Menu - File - New - Project - General - Project :
give the same name to the project that the directory where is the code.
So OpenSceneGraph

[OpenSceneGraph/trunk] but this not yet a C++ Project
E# Right click on this line - New - Convert to a C/C++ Make Project :
Now this is a C/C++ project. Eclipse scan the project directory, index
the code, found binaries, ...
E# Menu - Project - Properties - C/C++ Build : change the build location
and select OpenSceneGraph/release
for me this look like this : ${workspace_loc:/OpenSceneGraph/release}
E# Control + B : launch the build
E# Menu - Project - Properties - Run/Debug Setting.
Press the New button and select C/C++ Local Application.
Set the Name (for example the name of the program)
Set the C/C++ Application
In the Environment Tab, define the OSG_LIBRARY_PATH
if not already done in the Eclipse processus Environment
Click the OK button
E# Run - Open Run Dialog ...
Choose your application and click the Run button.
All work fine and you win.

Re: [osg-users] Eclipse and OSG
Hi Felix, now I am able to run the osg applications such as osgviewer, osgconv, osgarchive and osgversion. Great. My question is, if I am to create a program, do I do so under the same OpenSceneGraph directory or it has to be a different one. And Understand that Eclipse is just a front-end for your development tool-chain (emacs, gcc, gdb). If your application could be launch in a console without eclipse, your environment is well defined. I mean to say your 3rdparty library directory or everything need by your program is accessible. Else you need to adjust your environment. It's the same thing for eclipse, but you can define specific Environment variable for each application E# Menu - Run - Open Run Dialog ... - choose your application - Envirnment Tab -New To have completion in case you use different workspace. E# Menu - Project - Properties - C/C++ General - Path and Symbols - Includes Tab add header directory of the library you need. thereafter, what do I do. I am not sure to understand the question.

In theory one could use osgIntrospection separately from the OSG, but in practice its role is in support of the OSG so I don't see a big problem in have a link in there. If we need to refactor things in the future to get the full independence then we can cross the bridge of making the version number independent as well, its pretty trivial, but right now its certainly more practical to keep the versioning based on the core OSG one.

[osg-users] OpenGL Extension definition in OSG Headers
Hi Robert,
After seen and changed the patch provide by Art Tevs on the
GL_EXT_gpu_shader4 extension.
I have remarked that the extension guard
#ifndef GL_EXT_gpu_shader4
don't do
#define GL_EXT_gpu_shader4
I go through the glext.h and I see that it is define with the extension
functions definition.
ex of the Nvidia glext.h:
#ifndef __glext_h_
#define __glext_h_
#ifdef __cplusplus
extern C {
#endif
/* blablabla */
... lot of define ...
#ifndef GL_EXT_gpu_shader4
#define GL_SAMPLER_1D_ARRAY_EXT 0x8DC0
#define ...
#endif
... lot of define ...
#ifndef GL_EXT_gpu_shader4
#define GL_EXT_gpu_shader4 1
#ifdef GL_GLEXT_PROTOTYPES
extern void APIENTRY glGetUniformuivEXT (GLuint program, GLint location,
GLuint *params);
extern void APIENTRY glBindFragDataLocationEXT (GLuint program, GLuint
color, const GLchar *name);
extern GLint APIENTRY glGetFragDataLocationEXT (GLuint program, const GLchar
*name);
extern void APIENTRY glUniform1uiEXT (GLint location, GLuint v0);
...
So, to keep OSG consistent, we need to add
#define GL_EXT... 1
after each
#ifndef GL_EXT...
concerned file are FragmentProgram, VertexProgram, GL2Extensions,
PointSprite,
Thought ?

now you need to use the osgViewer::Viewer
which derive from osgViewer::View
which derive from osg::View
You have access to
- the scene graph by osgViewer::View::GetScene()
- the camera by osgViewer::View::GetCamera()

osgUtil::SceneView is use internally by osgViewer in osgViewer::Renderer.
And inherited its setting form the camera that osgViewer::Renderer render.
this is done in osgViewer::Renderer::updateSceneView.

2007/10/11, Pasquale Tricarico [EMAIL PROTECTED]:
Hi,
I'm updating a project to OSG-2.2, after several months (~6) of
interrupted development, and I'm facing a problem. Before I based my
code on the QT viewer example, with:
class ViewerQT : public osgViewer::Viewer, public GraphicsWindowQT {...}
and I could do:
ViewerQT * viewerWindow = new ViewerQT;
viewerWindow-getSceneView()-...;
Now, I've updated my code using the latest osgviewerQT example, where:
class AdapterWidget : public QGLWidget {...}
class ViewerQT : public osgViewer::Viewer, public AdapterWidget {...}
but now ViewerQT doesn't provide the getSceneView() method. How can I
recover it? I needed it mainly to modify the near/far ratio:
...-getSceneView()-setNearFarRatio(1.0e-8); // big scene, with many
tiny important details that need to be rendered
and for debugging/verbose output such as:
...-getSceneView()-getProjectionMatrixAsPerspective(fovy,
aspectRatio, zNear, zFar);
Maybe now OSG 2.2 offers better ways to perform these two tasks?
Thanks a lot,
Pasquale
(BTW, the first line of osgviewerQT.cpp says OpenSceneGraph example,
osganimate., got to love cut'n'paste ;)

This seem to be the good method.
you can try
1) do root-getOrCreateStateSet()-setMode(GLL_MULTISAMPLE_ARB,
osg::StateAttribut::OFF | osg::StateAttribut::OVERRIDE)
This is what I've been trying. More specifically
root-getOrCreateStateSet()-setMode(GL_MULTISAMPLE_ARB,
osg::StateAttribute::OFF | osg::StateAttribute::PROTECTED |
osg::StateAttribute::OVERRIDE);
after the viewer has been realized.
2) I think that number of sample is define when the OpenGL context is
created
so recreate a context on each switch of the number os sample you
want.
Why should I recreate a context? I think I should be able to
enable/disable Multisampling with setting the state mode ON/OFF.
How did you know that multisample is enabling/disabling.
Did you look the render ?
Yep, that is the case. I saw the render.
Did you do a request to OpenGL about multisample ?

I know there are pbuffers and you can probably latch on to pbuffer generation after each framing and then couple to a movie generation library but I see that the osgDB has a nice plugin architecture for reading and writing and was wondering with the Movie based plugins if there was a way to feed a plugin (if one exists for movie writing) to output frames at given rate. So basically init the plugin with some setup parameters and then start writing. Has anyone ever researched this through a raw OSG implementation and not coupled to like a GUI or anything like that?

Re: [osg-users] Still on osgintrospection...
Hi Manu 2007/12/5, Emmanuel Roche [EMAIL PROTECTED]: Suppose I have a class MyClass introspected I also some kind of template class MyTemplaceclass T, which can be built with the type T=MyClass, BUT this construction is done nowhere in our base library... I guess if I try to generate wrappers, the type MyTemplateMyClass will not be defined (ie reflected). What is best way to solve this problem ? Template reflection is not supported in osgIntrospection. You have to reflect each class create with a template. Done automatically by genWrapper when it found a template instantiation. Take a look to src/osgWrapper/osg/Array, each osg::Vec2, osg::Vec2s, osg::Vec3 ... are reflected. And by the way, I noticed that (with the SVN version of the genwrapper at least) it is not possible to use the option -p to generate VisualStudio project files. The option simply doesn't appear anywhere in the source code in fact, it that normal ? Well. really few person use genWrapper. I use it on Linux, Robert too. Never try on Windows. So perhaps this feature is firstly intended but never implemented.

Hi Manu 2007/12/5, Emmanuel Roche [EMAIL PROTECTED]: It's me again, sorry to ask so much, but I keep being surprised with this introspection stuff: Correct me if I'm missing something but since the operators of a class are not reflected (why ?), Well, you right again. Operator are not supported in osgIntrospection. how can you expect to do something as simple as the addition of two osg::Vec3 introspectively ??? Good question. OSG is bind in many other language than C++ with osgIntrospection and I don't know how this bind does to use operator. Perhaps simply not use operator at all. After look in OsgDotNet TODO list, a see that operator have to be implemented. So no solution for now. Again, feel free to do it :-).

Re: [osg-users] using osgIntrospection for own library
2007/12/6, Emmanuel Roche [EMAIL PROTECTED]: Hi David, What I mean in my ponit 2 is: - Suppose I have a library lib1 where I define my class Class1 - Suppose I build a wrapper for this library: lib1_wrapper Now, I build another library, lib2 where I define a templated class Class2T In this second library, I define the typedef : typedef Class2Class1 MyTypedef; - And now I try to build a wrapper for this lib2, lib2_wrapper. As Class1 is not in lib2, I guess the genwrapper will complain about no reflector being built for Class2 Class1 , GenWrapper work on one Header at time. So if your typedef Class2Class1 MyTypedef; is define in the same file of the template definition Class2T, It will create the Class2Class1 reflector. I also have a similar question on the same issue, more generally speaking: Suppose in my lib1, I define Class1 and the template Class2T, but never instantiating Class4Class1... Would there be a way to instanciate this type with through the wrapper then ? If you think to add typedef Class4Class1 myClass; in the wrapper source with the optional genWrapper.conf file, this is theoretically possible (from the compiler and linker view). But genWrapper don't support this kind of operation. A solution is to create a template reflector for your template Class2 and instanciate this template reflector in the wrapper source.

Re: [osg-users] osgIntrospection: areArgumentsCompatible() issue
Hi Manu,
You right :-).
I think in the introspection concept implemented by Marco Jez, If you use a
getCompatibleConstructor(...) or other low-level method in osgIntrospection,
you have to know the API as same as you write your code without
introspection.
David
2007/12/13, Emmanuel Roche [EMAIL PROTECTED]:
Hi there !
in the osgIntropsection framework, we use getCompatibleConstructor(...) or
getCompatibleMethod(...), etc... to get a function considering the
parameters offered. But it this process do the framework take into account
the possible implicit parameter constructions ?
I tried to check the sources, and as far as I understand, everything would
happen in the function if it was the case (for example for the implicit
convertion of a const char* object to std::string):
bool Reflection::accum_conv_path(const Type source, const Type dest,
ConverterList conv, std::vectorconst Type* chain, CastType castType)
{
// break unwanted loops
if (std::find( chain.begin(), chain.end(), source) != chain.end())
return false;
// store the type being processed to avoid loops
chain.push_back(source);
// search a converter from source
StaticData::ConverterMapMap::const_iterator i =
getOrCreateStaticData().convmap.find(source);
if (i == getOrCreateStaticData().convmap.end())
return false;
// search a converter to dest
const StaticData::ConverterMap cmap = i-second;
StaticData::ConverterMap::const_iterator j = cmap.find(dest);
if (j != cmap.end() (j-second-getCastType() == castType))
{
conv.push_back(j-second);
return true;
}
// search a undirect converter from source to ... to dest
for (j=cmap.begin(); j!=cmap.end(); ++j)
{
if ((j-second-getCastType() == castType)
accum_conv_path(*j-first, dest, conv, chain, castType))
{
conv.push_front(j-second);
return true;
}
}
return false;
}
... but I can't see anything concerning the type constructors here, so I
guess that to call a function you need to pass the exact type of parameter
needed (with an exception for the derived classes, and inheritance system),
for example:
with the function void myfunc(std::string arg1, osg::Node* obj)
the reflection framework would find a compatible method with the arguments
: { std::string(test) , and osg::Group* myGroup } but it won't find
anything with the pair { test, osg::Node* myNode }... Am I wrong ??

Manu.

Re: [osg-users] Big fonts in current SVN
Hi Jeremy I submit patch to Robert. So coming soon If all work fine.

The texture based fonts themselves haven't actually changed apart from the internals being reworked in terms of the new TexBase class, the actual rendering process should be the same. Robert.

My problems aren't like the ones Paul is seeing, but they're definitely new differences that weren't there Tuesday... Attached is a picture of the osghudlabel example from osgHUD. In the past, the text rendered has been nice and reasonably compact, but now there is almost an entire row of blank space between real row of text. This is the case for both my own fonts and the Times font provided w/ OSG. HOWEVER, this could just be my imagination, but was the font clarity improved with the recent changes to osgText? Even the spacing is wonky, I can swear they actually look a little crisper... not subpixel-aligned (as that would take a minimum of 3 passes so I hear), but still good. :) On Thu, 2007-12-13 at 13:11 -0700, Paul Martz wrote: Current SVN head seems to have extra-large screen oriented fonts.

Re: [osg-users] VPB in SVN
Hi Robert,
Have you put -W -Wall in CMAKE_CXX_FLAGS.
I have a lot of warning too, but I know that your code work fine with
this warning.
So I never take the time to fix them.
Cheers

Great, much appreciated.
I didn't mean warnings, there are some errors that should show up on
any compiler, such as a method declared as bool someMethod() not
returning a value... For example, in include/vpb/FileCache :
bool sync() { if (_requiresWrite) write(_filename); }
should be
bool sync() { if (_requiresWrite) return write(_filename); return
false; }
or something to that effect. I would have thought gcc would give an
error there... MSVC certainly does.
I've just done a clean build and g++ isn't reporting any warnings
whatsoever.
The above is an error of course, I'll fix this.
BTW, to correct the methods, I would like to know what is your
standard for methods returning error? 0/false = no error and 1/true =
error? Or 0/false = failed and 1/true = succeeded?
Typically true for succeeded/did operation.
Robert.

Re: [osg-users] crash with setTextureAttributeAndModes
Hi Otto
We don't have enough information to solve you problem.
Have you try to debug you application ?
Have you an available callstack to found where you application crash ?
Have you a simple program test which isolate the problem ?
but more simply, is your datasetList array store texture pointer in
osg::ref_ptr ?
Nobody can help you with this too little description.
This probably a misusing of osg code more than a bug in OSG.

Hi,
I'm having a crash with setTextureAttributeAndModes I don't know how to
fix.
To explain the issue. I have a list of data sets which hold a pointer to a
osg::Texture3D. The texture mixing is done in a shader and my texture update
function containing the following loop is called from an update callback.
Since the order of the textures can/must change i loop over the textures and
do this
Code:
osg::StateSet* sliceState = m_sliceNode-getOrCreateStateSet();
for ( size_t i = 0; i datasetList.size(); ++i)
{
osg::Texture3D* texture3D = datasetList[i] )-getTexture3D();
sliceState-setTextureAttributeAndModes( i, texture3D,
osg::StateAttribute::ON );
}
This works just find when adding one texture after another. However when
the order changes, thus overwriting a different order it crashes. So
apparently I'm doing it wrong.
Any help would be greatly appreciated.
...
Thank you!
Cheers,
Otto
