Re: [osg-users] [vpb] Building Virtual Planet Builder in Linux
Hi Nav, If you have installed gdal in your system, probably it will be autodetected. If you use a custom directory you will need to pass this information to cmake. There exists two ways: Use ccmake (you need to install cmake-curses package) .. instead of cmake .. and search for the entry GDAL_INCLUDE_DIR /usr/include/gdal(these are my autodetected values) GDAL_LIBRARY /usr/lib/libgdal1.7.0.so (these are my autodetected values) you can make use of cmake-gui if you feel more comfortable (you need to install cmake-qt-gui package) Use the paremeters as you said cmake ../osg -DGDAL_INCLUDE_DIR=/pathtogdalincludedir -DGDAL_LIBRARY=/pathtolib Cheers 2012/9/12 Nav Joseph nk...@tatapowersed.com @Jordi: Thanks for the timely reply.

Re: [osg-users] Using glDrawElements causes crash with osg::Stats
Hi Karl,
The OSG uses lazy state updating to aovid calling OpenGL when it's not
needed but when you do your own OpenGL calls outside this lazy state
update mechanism the OSG doesn't know the OpenGL state is now
different than when the OSG last applied something so ends up not
applying state when it should.
The way to fix it is to stop the state leakage from your own custom
cost vis the glPush*()/glPop*() or to tell the OSG that you've changed
the state via the osg::State::haveApplied*() calls or simply to use
the osg::State class itself for applying the state you want to change.
There are a whole series of methods for doing vertex array set up
that you can use so have a look at these.
Robert.

I have a situation that is requiring me to use raw gl commands in the
drawImplementation of an osg::Drawable. I have a double buffer that is not
updated fully until draw time as opposed to update time and I am not at
liberty to change this. Currently in the drawImplementation, I get the
current buffer, then perform glVertex and glNormal commands on the list of
vertices in the buffer. This works just fine and there are no problems other
than it can slow down the scene do to the number of verts. I was attempting
to convert this to a glDrawElements call as a quick improvement and saw a
noticeable performance increase. Everything is drawing just fine and I
haven’t found any slow downs or stability issues, with one exception. If I
enable osg::Stats, it crashes immediately and I have no idea why. I was
hoping someone might have some insight for me. Here is the
drawImplementation code:
{
//get the current active buffer
VertBuffer buffer = getCurBuffer();
//set up the client state
glPushClientAttrib(GL_CLIENT_VERTEX_ARRAY_BIT); //crashes immediately
without this
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_NORMAL_ARRAY);
//set up arrays
glVertexPointer(3, GL_FLOAT, 0, (GLvoid*)pmCoords);
glNormalPointer(GL_FLOAT, 0, (GLvoid*)pmNormals);
//draw
if (buffer.vertexList.size() 0)
{
glDrawElements(GL_TRIANGLES,
buffer.vertexList.size(), GL_UNSIGNED_INT, (buffer.vertexList)[0]);
}
//disable client state
glDisableClientState(GL_VERTEX_ARRAY);
glDisableClientState(GL_NORMAL_ARRAY);
glPopClientAttrib();
}
In this, VertBuffer, is just a structure that holds a std::vectorunsigned
int of the vertices to draw (vertexList), and some other info that is not
used during the draw. pmCoords and pmNormals are lists of all available
coordinates and their normals. The vertexList is just a list of indices in
these coordinates to draw at this time.
As I said, everything works fine if the draw is as follows instead:
glBegin(GL_TRIANGLES);
for (int ii = 0; ii buffer.vertexList.size(); ii+= 3)
{
glNormal3fv(pmNormals[buffer.vertexList[ii]];
glVertex3fv(pmCoords[buffer.vertexList[ii]];
glNormal3fv(pmNormals[buffer.vertexList[ii+1]];
glVertex3fv(pmCoords[buffer.vertexList[ii+1]];
glNormal3fv(pmNormals[buffer.vertexList[ii+2]];
glVertex3fv(pmCoords[buffer.vertexList[ii+2]];
}
glEnd();
I’ve tried copying the data locally from the buffer and that did nothing
different. I even tried to create a small array locally that contained the
same data. If I only drew 1 triangle it was fine, but if I tried to draw
more, it would sometimes work and sometimes crash.

Say, i have a clipped cube, can i add this object within another scene which is also clipped(using 4 clipplanes?) The simple answer has to be no as fixed function pipeline in OpenGL drivers and hence the OSG are typically limited to 6 clipping planes. However, you could implement your own shaders that overcome this limitation, using uniform to pass in the position of the clipping planes. The alternative would be to a multi-pass approach, but whether this is possible in your case will depend a great deal on exactly how you clipping things, i.e. object space vs viewport space.

Re: [osg-users] Using glDrawElements causes crash with osg::Stats
Alright so I adjusted my code to do everything through the osg::State,
including trying the osg::State's glDrawElementsInstanced instead of the
normal GL glDrawElements, and I am still having the same issue. It still
works normally but crashes when I enable stats. Is there a call I need
to make that I am missing? Here is the adjusted code:
Void MyDrawable::drawImplementation(osg::RenderInfo ri)
{
//get the current active buffer
VertBuffer buffer = getCurBuffer();
//get osg State and apply vertex and normal pointers
osg::State state = *ri.getState();
state.setVertexPointer(3, GL_FLOAT, 0, (GLvoid*)pmCoords);
state.setNormalPointer(GL_FLOAT, 0, (GLvoid*)pmNormals);
//draw
if (buffer.vertexList.size() 0)
{
state.glDrawElementsInstanced(GL_TRIANGLES,
buffer.vertexList.size(), GL_UNSIGNED_INT, (buffer.vertexList)[0], 1);
}
//disable vertex and normal pointers
state.disableNormalPointer();
state.disableVertexPointer();
}

Hi Karl,
The OSG uses lazy state updating to aovid calling OpenGL when it's not
needed but when you do your own OpenGL calls outside this lazy state
update mechanism the OSG doesn't know the OpenGL state is now different
than when the OSG last applied something so ends up not applying state
when it should.
The way to fix it is to stop the state leakage from your own custom cost
vis the glPush*()/glPop*() or to tell the OSG that you've changed the
state via the osg::State::haveApplied*() calls or simply to use the
osg::State class itself for applying the state you want to change.
There are a whole series of methods for doing vertex array set up that
you can use so have a look at these.
Robert.

I have a situation that is requiring me to use raw gl commands in the
drawImplementation of an osg::Drawable. I have a double buffer that is
not updated fully until draw time as opposed to update time and I am
not at liberty to change this. Currently in the drawImplementation, I
get the current buffer, then perform glVertex and glNormal commands on
the list of vertices in the buffer. This works just fine and there are
no problems other than it can slow down the scene do to the number of
verts. I was attempting to convert this to a glDrawElements call as a
quick improvement and saw a noticeable performance increase.
Everything is drawing just fine and I haven't found any slow downs or
stability issues, with one exception. If I enable osg::Stats, it
crashes immediately and I have no idea why. I was hoping someone might
have some insight for me. Here is the drawImplementation code:
{
//get the current active buffer
VertBuffer buffer = getCurBuffer();
//set up the client state
glPushClientAttrib(GL_CLIENT_VERTEX_ARRAY_BIT); //crashes immediately
without this
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_NORMAL_ARRAY);
//set up arrays
glVertexPointer(3, GL_FLOAT, 0, (GLvoid*)pmCoords);
glNormalPointer(GL_FLOAT, 0, (GLvoid*)pmNormals);
//draw
if (buffer.vertexList.size() 0)
{
glDrawElements(GL_TRIANGLES,
buffer.vertexList.size(), GL_UNSIGNED_INT, (buffer.vertexList)[0]);
}
//disable client state
glDisableClientState(GL_VERTEX_ARRAY);
glDisableClientState(GL_NORMAL_ARRAY);
glPopClientAttrib();
}
In this, VertBuffer, is just a structure that holds a
std::vectorunsigned
int of the vertices to draw (vertexList), and some other info that is
int not
used during the draw. pmCoords and pmNormals are lists of all
available coordinates and their normals. The vertexList is just a list
of indices in these coordinates to draw at this time.
As I said, everything works fine if the draw is as follows instead:
glBegin(GL_TRIANGLES);
for (int ii = 0; ii buffer.vertexList.size(); ii+=
3)
{
glNormal3fv(pmNormals[buffer.vertexList[ii]];
glVertex3fv(pmCoords[buffer.vertexList[ii]];
glNormal3fv(pmNormals[buffer.vertexList[ii+1]];
glVertex3fv(pmCoords[buffer.vertexList[ii+1]];
glNormal3fv(pmNormals[buffer.vertexList[ii+2]];
glVertex3fv(pmCoords[buffer.vertexList[ii+2]];
}
glEnd();
I've tried copying the data locally from the buffer and that did
nothing different. I even tried to create a small array locally that
contained the same data. If I only drew 1 triangle it was fine, but if
I tried to draw more, it would sometimes work and sometimes crash.

Re: [osg-users] Multiple Buffers on Multiple viewers
Just updating the status..
I finally figured this out, about 2am after several more attempts.
Basically, I learned that OpenSceneGraph isn't "magic" and simply
traverses the graph in order, so I had to be a bit more careful about
the order that I did things like constructing GC's, assigning viewports,
and attaching to the main graph.
Also, I finally learned how to use osgViewer::Viewer andm
osgViewer::CompositeViewer effectively.. Tu rns out I didn't need a
Composite Viewer, I could get my same functionality with multiple
contexts/viewports in a single Viewer.. and it's simpler, faster, and
less error-prone.
Liking OSG so far.. Bit of a learning curve from basic OpenGL, but not
as bad as I thought once I quit expected it to do magic things for me :)

Hi Fan, can you post a code snippet of what you tried? And some details about how it failed?

[osg-users] Releasing Graphics context?
Hi, My application renders on multiple screens and each attached with seperate graphics context. The apps demands addition/removal of any graphics context dynamically. Suppose when the context is removed and added subsequently for the same screen, it throws msg like unable to makeCurrentContext(...). Following to that, I couldn't render anything on to the screen. To release graphics context, I tried context-close(). I am not sure what needs to be done??

I created the solution, built it and worked fine except for 2 projects which concern QT. So the errors you posted were from OSG's Qt source? Since you did not post the full error text, I had no way of knowing that. Instead, I assumed you were seeing those errors in libosg. I rarely build OSG with Qt and have never built OSG/GL3 with Qt, so this is completely untested as far as I know. Qt 4.8.x does have GL3 context creation support, so it should be possible to make it work with OSG/GL3, but all the GL3 development efforts to date have been with osgViewer on Windows. If you need Qt support in OSG/GL3, please make any changes and post a submission. -Paul I managed to ran the osgsimplegl3. The only thing i did with the gl3/gl3.h is to add this path in visual studio's include path. thnx. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Releasing Graphics context?
Hi Akilan, I'm afraid you have provide too few details of how you create, use and destroy your graphics contexts to know what to be able to guess at what might be amiss and what might be appropriate. You also don't mention anything about the OSG version, operating system you've used etc. Robert.

Hi Ryan, I did attempt to check the required changes in earlier but double checking now I see that this particular commit can't have succeeded for some reason - perhaps I didn't spot an error report when I did the svn commit. I have just checked in the files again. Could you do an svn update and let me know how you get on. Thanks, Robert.

Re: [osg-users] Opengl 3
Hello These error i posted in my first post gave me a hard time. Even though I tried everything to make them disappear they simple didnt. I even tried to delete the whole OpenScenegraph/build directory and build everything from scratch. But they were still there. After that i deleted everything that had to do with openscenegraph and build everything again. Only then they disappeared (i used the same settings in cmake that i was using before). I cant explain it. So now I build open scene graph with the open gl 3 cmake settings and i run osgsimplegl3 with no problems (except for the 2 projects that relate with qt). Thank you for your time. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] RigGeometry setRigTransformImplementation, Update stops being called
Hi All
I'm doing some hardware accelerated skinning which I've done a few times
before, but i'm hitting a strange issue. So I do the below to in a visitor to
add my HardwareRigTransform to the RigGeometry.
Code:
osgAnimation::RigGeometry* rig =
dynamic_castosgAnimation::RigGeometry*(drawable);
if (rig){
//apply the HardwareRigTransform
rig-setRigTransformImplementation(new HardwareRigTransform);
stateMask |= GLES2ShaderGenCache::RIGGED;
}
However, once I do this RigGeometry::update() stops being called entirely
(added some console output to it). So in turn my hardware rig transforms
operator isn't being called.
Like I say I've done this before and as far as I can tell the code is the same,
so was wondering if someone might have run into a similar issue.
If I don't add the hardware rig transform I can see the rigged model (from fbx)
animating as expected.
Cheers
Tom

Re: [osg-users] RigGeometry setRigTransformImplementation, Update stops being called
Hi Again No worries I solved this, turns out my ShaderGen stuff was applying it's own drawable updatecallback, which was booting something off that osgAnimation was using. I just moved my callback up to the parent geode and everything seems cool. Hope this helps someone in the future.

Re: [osg-users] [vpb] [SOLVED] Building Virtual Planet Builder in Linux
Tried the GDAL macros and osg built successfully. VPB didn't; and it appeared to be because of the osg paths I had set wrongly in bash_profile. Anyway, I was under a time-crunch, so just rebuilt osg without gdal for the time-being. Thank you very much for helping out.

Re: [osg-users] Releasing Graphics context?
Robert I have 2 screens to be rendered with texture2D. I created context to each screen with appropriate screen id such a way, osg::ref_ptrpsg::GraphicsContext::Traits traits = new .; traits-x = 0; traits-y = 0; traits-screenNum = 0; //1 for other screen trait-width = screen_width; trait-height = screen_height; trait-doubleBuffer = true; trait-sharedContext = 0; osg::ref_ptrosg::GraphicsContext gc = osg::GraphicsContext::createGraphicsContext(trait.get()); The gc of each screen is set to a camera and camera as slave to view. When I render texture to both the screen I get the display fine. As soon as I try to remove one of the screen context using gc-close() and recreate again for the same screen, I get such an error. Further, I couldn't render any texture the updated screen.
