Re: [osg-users] CameraPreDrawCallback

What i have done so far is to create a myCameraPreDrawCallback which extends

GLObjectsVisitor. Also, when the callback is constructed i keep a reference
to the sub graph and then in the call back operator i let the sub graph
accepts the visitor.
I am not sure this is a right approach but i am puzzled with one thing is
how do you know the sub graph is complied and how to remove the call back?
You shouldn't need a reference to the subgraph, as the
DrawCallback::operator(..) takes the Camera that it's assigned to, and
the Camera contains the scene graph, and the Camera being just a Node.
In fact it takes less words in code...
struct CompileCallback : public osg::Camera::DrawCallback
{
virtual void operator() (const osg::Camera camera)
{
osgUtil::GLObjectVisitor gov;
const_castosg::Camera(camera).accept(gov);
}
};
Also, where should i get the camera from? is this just a camera i create or
i should get from the viewer?
viewer.getCamera()-setDrawCallback(new CompileCallback);

Hi J-S, On Jan 16, 2008 12:11 AM, Jean-Sebastien Guay [EMAIL PROTECTED] wrote: Yes, the gaps between tiles of different levels is usual right now. The --terrain feature is very new to VPB, its not yet productive ready so one would expect little items to not work 100%.

Even when I'm zoomed all the way in and all tiles are at the highest LOD, there are still those black lines. O.K. this isn't the lack of skirts then. And I totally understand about --terrain. Without knowing the details, I'd say that faster generation is always welcome! I'm just giving feedback to make sure it's not something in my setup or something platform-specific. Feedback is useful, especially when it uncovers problems that I not able to reproduce myself which does seem to be the case here.

Re: [osg-users] Adding shadow to an existing scenegraph
For tests, you may derive your ShadowMap from osgShadow::ShadowMap, override
init and cull methods. In this way you will be able to check if init was
called. Of course I have not tested it but the code should look more or less
like this:
#include cassert
class MyShadowMap: public osgShadow::ShadowMap {
public :
/** initialize the ShadowedScene and local cached data structures.*/
virtual void init()
{
assert( getShadowedScene() ); // ShadowMap::init does nothing
if this not
set
osgShadow::ShadowMap::init();
// now check if all vital resources were created
assert( osgShadow::ShadowMap::_stateset );
assert( osgShadow::ShadowMap::_camera );
assert( osgShadow::ShadowMap::_texture );
}
/** run the cull traversal of the ShadowedScene and set up the
rendering for this ShadowTechnique.*/
virtual void cull( osgUtil::CullVisitor cv )
{
// check if all vital resources were created by init
assert( osgShadow::ShadowMap::_stateset );
assert( osgShadow::ShadowMap::_camera );
assert( osgShadow::ShadowMap::_texture );
osgShadow::ShadowMap::cull( cv );
}
};
You may additionally call ShadowedScene-dirty() method. But I doubt it
helps, dirty flag is set anyway on creation, its generally used for
refreshing shadow params. What type of viewer uses your App ? J-S Guay
recently observed some issues with initialization of Shaders in ShadowMap
with CompositeViewer. Maybe this is related somehow.

Wojtek

If crash happens, its probably in some function on

called with stateset being
NULL ? Right ?
Hi, sorry for the late feedback on your new
suggestions. I pretty much do it like in your code
(sm-init after attaching the shadow technique). Still
you're right that the stateset being null is the
problem and this is still not solved.
Something must go wrong in the initialization. I am
building against the library so I cannot put a
breakpoint into the OSG-Code for the init function.
Previously I did not set the texture size for the
shadow map. But it seems this is the only difference
to the stuff you do in order to initialize and set
everything for the shadow.

Re: [osg-users] Performance Problem
Hi Jin,
quit hard to say what exactly going wrong or not. you just mention the size
of the database, but nothing about the structure of it. 1.15GB is a huge
database if you have to hold the hole in your local memory. the ive is more
or less a memory dump, when you like to open a file it gets hole loaded or
nothing. so i guess your application consume a lot of memory. may the GPU is
the bottle neck (nbr of primitives, triangles,...) or just the CPU or
memory. so what kind of data are you working on? paged? LOD? ...

Re: [osg-users] VPB in SVN
Hello Robert, I've been comparing the texture setup up code in both VPB and osgTerrain and found that VPB uses CLAMP_TO_EDGE while osgTerrain::GeometryTechnique itself just used defaults. I've changed osgTerrain::GeometryTechnqiue to use CLAMP_TO_EDGE, testing under linux doesn't show any difference, but there is a chance that it might change things under Windows. The change is now checked in. Just updated OSG from SVN to get the changes to osgTerrain::GeometryTechnique, recompiled, and regenerated the terrain, and it's fixed. No more black lines. Thanks Robert. I don't think there are any other issues right now, unless you want me to download some other data set and do some tests on it...

This seems to be caused by the stringstream not holding on to the result of its str() method.

I solved it by making a static std::string (instead of a static std::stringstream) and returning that. I also added code so the version string is generated only once, like in OSG, but if you had good reasons to not do that, it's not significant anyways (for a function that will likely only be called once in the life of a program). It now prints the same thing for me as it does for you. Diff attached. Still trying to figure out what's happening for the other problem. BTW, what about the images? I asked if it was possible for you to make them available (as an osgHUD-Data package or a directory in your SVN or whatever)... Once I get serious textured examples I'll certainly put them in SVN. Right now they're just randome images off my machine, and it would be safe to replace them with anything out of the osgdata SVN project itself.

[osg-users] PBO and updating textures
Hi all,
I apologize in advance for the wordy post!
I've recently ventured down the path of learning about the use of PBO's in
GL. I've come to
the conclusion that we could probably use this functionality in some of our
texture-based pipelines.
Anyway, I've run into an issue when trying to use them with 3D textures and
I think it's just because
3D textures aren't used nearly as much as 2d textures in this community(at
least until recently!).
I think the problem we're facing is that currently,the PixelBufferObject
class only updates based on data set to an osg::Image.
However, for our 3D texture pipelines, we update our textures via a
subloadcallback. We eventually call
glTexSubImage3D to update the texture data with external data similar to
below:
*void cfdUpdateTextureCallback::subload( const osg::Texture3D texture,
osg::State state ) const
{
if( !textureDataHolder )
{
return;
}
if( **textureDataHolder**-TimeToUpdateTextureData() )
{
texture.getExtensions( state.getContextID(), false
)-glTexSubImage3D( GL_TEXTURE_3D,
0,
0, 0, 0,
_textureWidth,
_textureHeight,
_textureDepth,
GL_LUMINANCE_ALPHA,
GL_UNSIGNED_BYTE,
( unsigned char* )**textureDataHolder**-GetTextureData()
);
}
}
}
*I looked at osg::Texture::applyTexImage2D_subload for an example of how to
use PBO's with textures and implemented this in
my subload callback but my data only displays the original image data.
Looking in the function for PixelBufferObject::compileBuffer,
I found that the buffer data is only updated on the data in the image that
the PBO is associated with.
So...how do I update the image data or the PBO? Ideally, I'd like to be
able to set the data to use for updating the PBO.
We were using the subload callback to manage the data in the texture but now
it seems like
somehow we'll have to manipulate the data in image but I don't see an
interface for that. Am I missing something or has this situation
not been addressed? I have some ideas on how to fix it but they all seem
like a hack so any input/advice there would be greatly appreciated.

Re: [osg-users] osgHUD compilation on Windows
Hello Jeremy, Still trying to figure out what's happening for the other problem. Problem figured out. It was once again an issue of linking release libs with a debug executable (which is bad(tm) on Windows). I added in the modifications to the CMake files to be able to compile with a 'd' suffix (both libs and executables), and link to the libs with 'd' in them. You could choose to do it conditionally on Windows only, but that's how OSG works as well. Now, it compiles and most examples run well. One issue I have is that I'm getting an assertion in osgHUD::Window::_forEachAssignOrApply() which is only used in osghudframe and osghudtable. It looks like the Windows C++ runtime doesn't like incrementing past the last element. I'll add a check for that. The other thing is that I don't know if the examples give the visual output you expect. I'll try to make a screenshot of each example's initial state, at least that will give us something to go on. I'll wait until you've merged the other diffs I sent you before sending you these CMake changes, so the diffs don't overlap. Oh, and I (finally!) understood that the images you used for your examples came from the OSG-Data package... Sorry about that.

Re: [osg-users] osgHUD compilation on Windows
Hello Jeremy, Okay, changes are all merged! Looks good, except for one thing: I mentioned that -DOSG_LIBRARY should only be set for the lib, not for the examples (it's related to the _declspec(dllimport)/_declspec(dllexport) stuff in OSG's include/osg/Export header). So in the diff attached, I moved the WIN32 block back to the end of the file, after the ADD_SUBDIRECTORY() lines. Anyways, here is the next batch of changes, with that change added as well. I haven't yet started working on the std::bad_alloc I'm getting, will get back to you on that later. I run all the examples in valgrind pretty religiously and if I ever see anything weird I'll usually fix it right away. Yeah, don't worry, I didn't think it was anything in your code - memory leaks rarely have any visible effect, especially with 3GB of RAM! It was obviously something related to DLLs and such, and as it turns out it was the usual problem of linking a debug executable to release libs (and vice versa). The necessary changes are attached. I'll fix the iterator issue and then make some screenshots next.

Re: [osg-users] osgHUD compilation on Windows
Hello Jeremy,
I'll fix the iterator issue and then make some screenshots next.
Ok, fixed. It's a bit sad that I have to use the indices instead of iterators,
but in MS's C++ runtime, an assert is generated whenever you try to increment
an iterator past the end of the vector.
_Myt operator+=(difference_type _Off)
{// increment by integer
_SCL_SECURE_VALIDATE(this-_Mycont != NULL);
_SCL_SECURE_VALIDATE_RANGE(
_Myptr + _Off = ((_Myvec *)(this-_Mycont))-_Mylast
_Myptr + _Off = ((_Myvec *)(this-_Mycont))-_Myfirst);
_Myptr += _Off;
return (*this);
}
I can't even change the check to
for(ConstIterator i = _objects.begin() + begin; (i + add) e; i += add) {
because operator+ uses operator+= ! So I'll run into the same assert.
_Myt operator+(difference_type _Off) const
{// return this + integer
_Myt _Tmp = *this;
return (_Tmp += _Off);
}
So I'm really stuck and need to use the index:
for(unsigned int i = begin; i _objects.size(); i += add) {
That works. I had to make a similar change to Table.cpp. Diffs attached.
Now all the examples run on Windows. I'll take screenshots to make sure the
output is the same (should be, but I'm not sure).

Re: [osg-users] Performance Problem
Hi adegli,
Thanks for your reply.
My ive-format models are exported from 3dsmax with osgExp plugin.
Yes, I get the whole database loaded into memory. Actually, after loading the
whole database, my harddisk works busily, I think maybe this is because my
application use up all the memory. Then, how can I avoid this?
As far as paged or LOD, I have not used them in my application because that I
don't know how to use them. Is there any tools to get lower level of detail
models from my original ive models?
Owing to my poor English, I wish I could descript my question clearly?

Hi Jin,
quit hard to say what exactly going wrong or not. you just mention the size
of the database, but nothing about the structure of it. 1.15GB is a huge
database if you have to hold the hole in your local memory. the ive is more or
less a memory dump, when you like to open a file it gets hole loaded or
nothing. so i guess your application consume a lot of memory. may the GPU is
the bottle neck (nbr of primitives, triangles,...) or just the CPU or memory.
so what kind of data are you working on? paged? LOD? ...

Hi,
I have written a viewer on Window XP using MFC based on osviewerMFC example
code. I add eighteen IVE-format models(about 1.15GB on harddisk) as children
node to the scene's root group node, then, the rendering process gives a sharp
slowdown and the FPS decrease to less than 1.0 . Could anyone give me some help
on how to enhance the rendering performance?
I am using OSG 2.0. The code I used to add a IVE-format model to scene is:
..
// Load the model from the model name
osg::ref_ptrosg::Node m_pNewModel;
m_pNewModel = osgDB::readNodeFile(strModel.GetString());//strModel
is CString variable contains the model's full path.
if (m_pNewModel.get())
{
osgUtil::Optimizer optimizer;
optimizer.optimize(m_pNewModel.get());
optimizer.reset();
// Add the model to the scene
mRoot-addChild(m_pNewModel.get());
//mRoot is the scene's root node defined as osg::ref_ptrosg::Group
}
..

Hi GuiYe,
All the cull settings that you've being doing with SceneView in 1.2
can now be done directly with osg::Camera as it subclasses from
osg::CullSettings. For the most part you just need to rewrite the

Re: [osg-users] Performance Problem
Hi Jin, Try compressing the scene's texture via: osgconv --compress mymodel.fmt mymodel.ive ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Performance Problem
Try loading each of the 18 models separately and see which models decrease your FPS the most. Then study those models closer to see the cause. Press the 'S' key twice in osgviewer and look at how much time is spent culling, drawing, and updating. Some possible causes 1. Too many triangles. 2. Too many different objects sometimes artists seperate their Geometry into to many groups. 3. Not using LODs 4. Too many StateSet changes. 5. Textures use too much memory. 6. And more others Brian ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgHUD compilation on Windows
Hi Jeremy, Actually, rev59. :) Yep, that did it. Results seem to be the same as yours too, obviously. I'll try to keep in touch with your latest developments and inform you if there are other problems. In the mean time, I'll try and use it in a few little tests. Again, good work!

Re: [osg-users] VPB in SVN
NVIDIA drivers have a control for default texture clamping. I know this used to default to the CLAMP_TO_EDGE, and if you wanted OpenGL spec-compliant behavior, you had to manually change it to CLAMP_TO_BORDER. I wonder if this is the cause of the black lines issue? CLAMP_TO_BORDER with full 0 to 1 texture coordinates and no border specified in the texture, that would cause a black edge where the texture tiles meet... If this is the case, proper use of the texture border would eliminate the problem.

Re: [osg-users] VPB in SVN
Hi Paul, NVIDIA drivers have a control for default texture clamping. I know this used to default to the CLAMP_TO_EDGE, and if you wanted OpenGL spec-compliant behavior, you had to manually change it to CLAMP_TO_BORDER. Thanks for the details! I'm always impressed at how difficult it seems to be for driver writers to conform to a spec... I'm sure it's more difficult than it seems, but I wonder if they're really trying hard enough? I wonder if this is the cause of the black lines issue? CLAMP_TO_BORDER with full 0 to 1 texture coordinates and no border specified in the texture, that would cause a black edge where the texture tiles meet... If this is the case, proper use of the texture border would eliminate the problem. Yep, that's whay Robert ended up doing.

Re: [osg-users] openscenegraph.org's Chinese mirror will be run after the new
Hi Robert and all: Thanks for Robert's support and his kind help in process. This Chinese mirror have spent more time for his surface looks like the English official website. I use the Trac and almost all the images and chart's come from openscenegraph.org, the datebase is a very important difficulties in Tracs. I have finish part of the mirror which is most looks like openscenegraph.org(99%, the 1% is the language difference).I think this will be help the osger in China to realize the mirror come from openscenegrph.org. It also include some Chinese, but some are translating from English also, such as Navy's tutorials. Every nation's condition have some difference in using OpenSceneGraph. But when the website is finished after Feb 7, I will send a difference between the two site and if some need the articles or the tutorials in Chinese, I and my colleagues will translate it into English. For our poor English, Robert will edit it. OpenSceneGraph is famous for two points, the first is powerful, and the last is poor document. Mutiple langulage mirror is very useful for every nations.Someone have interesting in it? Thank you Robert.

[osg-users] stereo projector support in OpenSceneGraph
Hi, our lab get a new stereo projector connects to two video outputs on one Quadro FX 5500. Does OpenSceneGraph support such stereo display? I used to do stereo display using two machine and now I have no idea how to do it using one single video card. Any information will be appreciated.
