Re: [osg-users] PagedLOD preprocessing
Paul Martz napsal(a): [...] The naïve approach -- just let OSG load it -- appears to cause a guaranteed frame rate hit. I imagine you could break the texture up into smaller chunks and let OSG page each in incrementally as it comes into range. Yes, breaking the texture into the smaller ones looks like necessary. I made already some measurements of glTexImage2D. 32 0,040,52 64 0,060,61 128 0,170,82 256 0,421,6 512 1,8 4,8 102411,317,9 204842 69 4096170 6500 The first column is texture size, second time in milliseconds for GF 6600 and the last column is time for ATI 1950. You may notice driver bug for 4096 ATI textures. Anyway, loading a large scene for preprocessing seems not trivial - hacks to OSG plugin will be probably necessary.

Re: [osg-users] PagedLOD preprocessing
On 9/10/07, Paul Martz [EMAIL PROTECTED] wrote: Hi Robert -- Assuming you've massaged your database so that the highest res textures only get loaded/displayed at close ranges, how would you use OSG to avoid the (seemingly inevitable) cost of loading the large texture from disk and sending it over the bus to the graphics card when it is time to be rendered? The naïve approach -- just let OSG load it -- appears to cause a guaranteed frame rate hit. I imagine you could break the texture up into smaller chunks and let OSG page each in incrementally as it comes into range. Or, you could preload all textures onto all displays at startup with the GLObjectsVisitor, though this could tax system RAM for large datasets. Could PROXY_TEXTURE help? At least it would tell OpenGL hey, some big data is coming, eventually but there would still be the disk access and bus transmission cost, so I imagine it's not a solution. Robert, your thoughts please. We don't have a texture manage at present, but one could in theory develop one to load balance memory on the GPU. With GPU memory sizes going up all the time this is probably getting less of a problem. W.r.t loading incrementally and compiling OpenGL data. In 2.1.x and SVN there is support for using a background compile context - this is a pbuffer per graphics window that is shared with the graphics context and has its own graphics thread that runs the compile and object clean up. One can enable compile contexts via: osgviewer mydata.ive --cc Also see osg::GraphicsContext::createCompileContext(..) function.

Re: [osg-users] keyboard autorepeat
HI Anders, There isn't such a feature right now. The changes back in June were down to making X11 behave more like Windows and OSX w.r.t keyboard repeats. I presume switching off keyboard repeat will require a platform specific call to the windowing system to switch it off. I don't know about the implementations so will need to defer to others.

std::string cacheFile = localCacheDir + '/' +
fileName;
osgDB::makeDirectoryForFile( cacheFile );
std::ofstream fout(cacheFile.c_str());
std::ios::pos_type pos = sio-tellg();
char c;
while(!sio-eof())
{
c = sio-peek();
fout.put(c);
}
fout.flush();
fout.close();
sio-seekg(pos);
//***
readResult = readFile(objectType, reader, *sio, local_opt.get()
);
}
but I find that the result is wrong. it is seen that some unwanted '0D' was
writen into the file.
why?

Re: [osg-users] Multiple GraphicsContexts
Hi John, I can only guess that you first need to realize the window before you can share it. For an example of sharing contexts see src/osg/GraphicsContext.cpp and look for the createCompileContext() code segment. Robert. On 9/11/07, John Donovan [EMAIL PROTECTED] wrote: Robert Osfield wrote: If you wish to reuse texture objects generated by one context then you need to share the various contexts with each other. You can set this via the GraphicsContext::Traits::sharedContext variable. Ah! OK, that makes sense. But I am having problems with it... I have the following: ref_ptrGraphicsContext::Traits traits_rtt = new GraphicsContext::Traits; traits_rtt-x = 500; traits_rtt-y = 880; traits_rtt-width = totalWidth; traits_rtt-height = vpHeight; traits_rtt-windowDecoration = false; traits_rtt-doubleBuffer = true; traits_rtt-sharedContext = 0; ref_ptrGraphicsContext gc_rtt = GraphicsContext::createGraphicsContext(traits_rtt.get()); ref_ptrGraphicsContext::Traits traits_view = new GraphicsContext::Traits; traits_view-x = 500; traits_view-y = 800; traits_view-width = totalWidth; traits_view-height = vpHeight; traits_view-windowDecoration = true; traits_view-doubleBuffer = true; traits_view-sharedContext = gc_rtt.get(); ref_ptrGraphicsContext gc_view = GraphicsContext::createGraphicsContext(traits_view.get()); Then I have a viewer with a camera rendering to a texture, and a viewer rendering a textured quad to a window. But when I call Viewer::frame() on the viewer that renders to the window, I get the following error messages: Windows Error #170: [Screen #0] GraphicsWindowWin32::realizeImplementation() - Unable to share OpenGL context. Reason: The requested resource is in use. Error: [Screen #0] GraphicsWindowWin32::makeCurrentImplementation() - Window not realized; cannot do makeCurrent. Are there any examples I can work off? I've tried a search for sharedContext in the OSG project, but I just get the implementation code, not any example code. Incidentally, I've upgraded to 2.1.9 without a hitch. -J __ This email has been scanned by the MessageLabs Email Security System.

Re: [osg-users] osgdotnet Generator
Hi Wolfgang,
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.

Hi Rafa, I had the same problem 1 week ago. I use Linux Fedora 7. When compiling, the default glext.h used is the glext.h provide by the mesa package. I have a Nvidia graphic card and the nvidia package for fedora provide an up to date glext.h. But this header is in the /usr/include/nvidia/GL/ directory I just do a symbolic link from /usr/include/nvidia/GL/glext.h to /usr/include/GL/glext.h All build fine now.

Re: [osg-users] Please test SVN version of OpenSceneGraph
It should be the bad VS2005 problem
2007/9/11, sicong he [EMAIL PROTECTED]:
My VS2005 report me:
Compiler Error C2668. 'log' : ambiguous call to overloaded function.
I see in VS2005, function log have only works with double or float:
double __cdecl log(__in double _X);
So you should convert int to double:
inline int log2(int v) { return static_castfloat(floorf(log((double)v) *
INVLN_2)); }
But same problem happened to floor function. In VS2005 floor function
works with double or float, so log2 should return a float or double:
inline float log2(int v) { return static_castfloat(floorf(log((double)v)
* INVLN_2)); }
And this new log2 function fix the build problem.
2007/9/11, Art Tevs [EMAIL PROTECTED]:

[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 ?

Re: [osg-users] OpenGL Extension definition in OSG Headers
Hi David,
We don't need to import all the extension prototypes and defines
provided in glext.h, only the ones that the code uses. We also
aren't trying to #define everything as per glext.h to work as a
replacement, so its not required to do a #define GL_extension_name
within each block of defines.
What you see in the OSG headers works pretty well, you do get little
hiccups like we've seen today, but in these are typically pretty easy
to fix once the correct defines are set.
Robert.

Hmm, seems to be a good idea, since it would really define only those things, which are not defined.

Re: [osg-users] Please test SVN version of OpenSceneGraph
Hi, Sicong.
The proposition you made before are not really a good
solution, since you force the compiler to use the
double version of the log function, which might be
slow.
For the integer version of the log2, I have another
proposition. I have attached a newly patched file. The
integer log2 function does compute the binary
logarithm based on the bit structure of the number.
The method seems to be faster than a double
computation of log2.
Robert, please check out if you are agree with this
version.
Sicong, please check out if it is now working for your
system. Actually it should now.
Cheers, Art
P.S. There exists some nice methods to compute binary
logarithm really fast, but they relly on certain CPU
instructions. This function does provide a generic
solution, which might not as fast, but still fast
enough ;-)

2007/9/11, sicong he [EMAIL PROTECTED]:
My VS2005 report me:
Compiler Error C2668. 'log' : ambiguous call to
overloaded function.
I see in VS2005, function log have only works with
double or float:
double __cdecl log(__in double _X);
So you should convert int to double:
inline int log2(int v) { return
static_castfloat(floorf(log((double)v) *
INVLN_2)); }
But same problem happened to floor function. In
VS2005 floor function
works with double or float, so log2 should return
a float or double:
inline float log2(int v) { return
static_castfloat(floorf(log((double)v)
* INVLN_2)); }
And this new log2 function fix the build problem.
2007/9/11, Art Tevs [EMAIL PROTECTED]:
yes, it seems that math.h does not define the

Re: [osg-users] Please test SVN version of OpenSceneGraph
Hello Art, Yes, I was watching the discussion about log2 on osg-submissions. My concern is more about fixing building issues than code improvement, so whichever way you decide is best works for me. Just wait couple of days or make your proposition of how to fix the problem (see osg-submission and osg-users list for more details about log2 issue). Well, in the mean time I sent about an hour ago modified versions of the Texture*.cpp files that cast the result of log2 to a float before taking the floor of it. If you don't do that, you get compile errors on Visual C++ as I said. And if log2(int) is ever removed, there will be another problem because maximum(int, int) returns an int, so then VC++ will give an ambiguous call for log2 (float or double). But we'll see to that when it happens.

Re: [osg-users] Please test SVN version of OpenSceneGraph
Oh yeah.. I remember now. I have to add -DCOMPILE_USING_TWO_PARAM_sched_setaffinity to the compile flags.. thanks, sorry for the bother. ml On Sep 11, 2007, at 2:06 PM, Robert Osfield wrote: Hi Mike, I think the error you have is down to RedHat shipping sched_setaffinity with the a non standard number of parameters for a while. There is a code path in OpenThreads to cope with this, but I can't recall if this is picked out by CMake. Have a root through the code. Robert.

[osg-users] CMake problem
INCLUDE_DIRECTORIES( ${INVENTOR_INCLUDE_DIR} ) seems to fix include
problem, anyway INVENTOR_LIBRARY_DEBUG, although defined, is not used
for debug linking - as a result, debug build is broken while release
seems ok.
I think, something is broken in the general OSG scripts related to
*_DEBUG variables.

Hi,
this is probably question on Luigi:
Inventor plugin CMakeLists.txt stopped working - it is neither including
necessary includes correctly detected by FindInventor.cmake, nor linking
libraries correctly detected in the same way. Therefore, the plugin not
compiles.
Do you see any problem in the file?
(inlining it for your convenience)
INCLUDE(OsgMacroUtils)
SET(TARGET_SRC
[...]
)
SET(TARGET_HDRS
[...]
)
ADD_DEFINITIONS(-DCOIN_DLL)
SET(TARGET_EXTERNAL_LIBRARIES ${INVENTOR_LIBRARY} )
SETUP_PLUGIN(iv)
Many thanks,
John
