Thanks in advance you can try one of the NSBundle-methods: NSBundle* bundle = [NSBundle bundleForClass: [self class]]; std::string plugin_path( [ [bundle builtInPlugInsPath] cString]); This will give you the path to the PlugIns-folder inside your bundle. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osg::Geometry and GL_PRIMITVE_RESTART
Hi Sergey,
thank you, now its working perfectly
cheers, ParticlePeter
Hi, Peter
This is because osg tries to compute bound of drawable based on vertices it
uses. So if your restart index behind memory allocated for vertices storage osg
will go out of array bound when computing bounds of drawable, thats where your
access violation comes from. You can try to avoid this with setting initial
bound yourself and\or setting your own computeBoundCallback on drawable.
Another way is to add additional vertex to vertex array and use it index as
restart index to make osg bound computation happy.
Cheers,
Sergey.

Hi J-S,
Yes, thank you, that did the trick, now it works. And to answer my question
above, it has to be glEnableClientState, otherwise its not working.
I have one more issue now. Sergey, I am getting a Access Violation Exception
directly after calling viewer.run inside osg::Vec3f line 84, if I use the the
default restart index of USHRT_MAX.
To debug this, I added a method to set the index, and got wired results. I
created an 18 Elements TriStrip, code is bellow. When I set the restart index
between 0 and 18 (18 is not a typo ), everything is fine. When I set it to 19
and higher I get this in the console:
Code:
CullVisitor::apply(Geode&) detected NaN,
depth=-1.IND, center=(-2 0 -7.942e+037),
matrix={
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
}
If I set the index between 1000 and 2000 it works right ( ! ), and if I set it
to 5000 and above I get the Access Violation Exception again.
Do you have any idea what's going on ? Is this related to not creating an
StateAttribute ?
TestCode, uses the class posted by hybr:
Code:
#include "DrawElementsUShortRestart.h"
#include
#include
#include
osg::ref_ptr< osg::Node> createDrawElements() {
osg::Geometry * geom = new osg::Geometry() ;
osg::Vec3Array * vrts = new osg::Vec3Array() ;
geom -> setVertexArray( vrts ) ;
unsigned int numVrts = 18 ;
// Create Vertex Positions for TriStripe
for( unsigned int i = 0 ; i< numVrts / 2 ; ++i ) {
vrts -> push_back( osg::Vec3( i , 1.f , 0.f ) ) ;
vrts -> push_back( osg::Vec3( i ,-1.f , 0.f ) ) ;
}
// Create a PrimitiveRestart DrawElements
DrawElementsUShortRestart * drawElems = new DrawElementsUShortRestart() ;
// This is set to false by default in the constructors initializer list

// Added this method to the DrawElementsUShortRestart Class

for( unsigned int i = 0 ; i< numVrts ; ++i ) {
if ( i == 9 )
drawElems -> push_back( 1000 ) ; // Try also 20 and USHRT_MAX
drawElems -> push_back( i ) ;
}
geom -> addPrimitiveSet( drawElems ) ;

osg::StateAttribute::OFF ) ;
geom -> getOrCreateStateSet() -> setAttributeAndModes(

osg::PolygonMode::LINE ) ) ;

Re: [osg-users] Multiple Shaders
Glenn, Thanks for the response. Do you know where I can find the osgvirtualprogram example? The program I have worked on has recently moved from osg 2.2 to 2.8.3 (dark ages, I know). I do not see osgvirtualprogram in the osg examples directories for 2.2, 2.8.2, or 2.8.3. I am adding precipitation effects (and dust effects) to a project that currently uses shaders produce a rendered scene that represents sensor returns - the render target is read back by the main program, where the data is consumed. For the app/channel that has the sensor, the program/shader is added to a node near the top of the tree. I have added the precip effect program/shader to a node slightly below this one - at the same level as the top terrain and entities node. The sensor shader basically does range calculation, applies some error, and does some processing for alpha fragments. For the visual channel, that has no higher shaders, this works fine. However, for the sensor channel, the precip particles don't get seen by sensor shader. My implementation of rain/snow is based on a slightly modified osgPrecipitationEffect. Perhaps shader is not the way to go for the precip effect, but I thought it would provide the best efficiency. Nevertheless, I can definitely see the need in the near future to have multiple, accumulated, non-overriding effects. Currently, I would like to be able to have the results from osgPrecipitationEffect like shader be seen by the higher sensor shader. Any thoughts?

Re: [osg-users] Multiple Shaders
Stephen, That example is in the main distro; you need to enable the examples in CMake to see it. The source is here http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgvirtualprogram Yes, yours is a case for shader composition. PrecipitationEffect is self-contained so you would need to modify it to make it work in a composition framework. BTW here is a write-up on the shader composition approach we use in osgEarth. Like I said, we started with VirtualProgram and extended it to support user function injection. http://osgearth.org/wiki/OeDevelShaderComposition Glenn Waldron / Pelican Mapping / @glennwaldron On Tue, Aug 9, 2011 at 10:03 AM, wrote: > > > Glenn, > Thanks for the response.

Re: [osg-users] dimension oh a model
In response to David's post (which I didn't see until now), it's fairly straightforward to back-transform a pixel into world coordinates. I've posted on this in the past, email me offline and I'll send you more info about it. Sanat, one thing I learned in the GIS classes years ago is that you must be very careful to have all of your GIS data in the same projection/ellipsoid/units, or they won't mix well. If your buildings are too large, then perhaps they were modeled in feet and your Earth is modeled in meters, for example. If you don't have any meta data for the models to tell your application what coordinate system and units the model uses, there is no magic software trick to handle that situation. So you have two solutions: Either manually put all your models (Earth and buildings) into the same coordinate system and units, or manually ensure that each model contains the necessary metadata so that your application can transform them as needed into a common coordinate system and units. -Paul On 8/9/2011 10:24 AM, Sanat Talmaki wrote: Hi David, I guess I am replying to a rather old post, but I'll try my luck anyway: Adding to your post on getting the size of the terrain, I had a similar question in mind.

Re: [osg-users] Determining whether a node is active in UpdateVisitor.
Hi Mark, I don't know if this is optimal or not, but one thing you could do is use the NodeVisitor::getNodePath() method. You can look through the path to find any switch nodes, and use the Switch::getChildValue(const Node*) method to see if the next node in the list is on or off. This is of course assuming that this is what you meant by active.
