Re: [osg-users] [build] cannot build osg on mac os x 10.6.5 with gcc version 4.2.1
Hi, I thought OSG_NOTIFY_LEVEL was a cmake flag not an env. flag. So I built source from scratch, generating xcode.proj and not makefile this time. I set OSG_WINDOWING_SYSTEM to Cocoa (from Carbon) OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX to imageio (from quicktime) and it builds, although I get many warnings -literally for each .dylib used-, e.g. ld: warning: duplicate dylib /Users/nikos/NetBeansProjects/OpenSceneGraph/OpenSceneGraph-2.8.3/Bin/lib/Debug/libosgTextd.dylib How can I suppress this?

[osg-users] LineSegmentIntersector::Intersection contains no indexList
Hi, I am trying to get uv coordinates and color of a point I found using the LineSegmentIntersector. My problem is that the found intersection has no indexList so I cannot use the code used in osgmovie. This short code example should boil down to the point: Code: osg::Box* b = new osg::Box( osg::Vec3d(0,0,0), 1.0f); osg::Geode* g = new osg::Geode(); g-addDrawable( new osg::ShapeDrawable( b ) ); osg::ref_ptr osgUtil::LineSegmentIntersector lineSeg = new osgUtil::LineSegmentIntersector(osg::Vec3d(0,-2,0), osg::Vec3d(0,0,0)); osgUtil::IntersectionVisitor findIntersections(lineSeg.get()); g-accept(findIntersections); osgUtil::LineSegmentIntersector::Intersection currHit = lineSeg-getFirstIntersection(); osg::Vec3d intersecPnt = currHit.getWorldIntersectPoint(); int vecArraySize = currHit.indexList.size(); int vecRatioSize = currHit.ratioList.size(); intersecPnt is correctly found, but vecArraySize and vecRatioSize is zero. I read through some layers of osg code and it seems my proble is the treatVertexDataAsTemporary variable. It prevents at the end of TriangleIntersector::operator () (part of LineSegmentIntersectorUtils in linesegmentintersector.cpp) that the found three vertices used to compute the intersection are inserted into the result as they are temporary. How do I get the correct uv coordinates in such a situation or how do I force the inclusion of the needed vertices?

[osg-users] osgUtil::Optimizer MERGE_GEODES MERGE_GEOMETRY TEXTURE_ATLAS_BUILDER
Hi all, I am trying to improve our scene graph layout for some of our data, and my first step is to improve our use of osgconv with various optimizer settings. We've been using it for a while but never really examined the results to see if it was doing what it was supposed to. Starting with a really simple object, I have some parts that need to stay separate (in terms of nodes and textures) so I have marked them as DYNAMIC, and the rest I have marked as STATIC. These are all under a single Group. There are 8 geodes and 8 geometry there, using about 4 different textures among them. Then, I set OSG_OPTIMIZER=MERGE_GEODES MERGE_GEOMETRY TEXTURE_ATLAS_BUILDER abd run osgconv with -O OutputTextureFiles to optimize the model. I was expecting the 8 geodes and 8 geometry to become a single geode and geometry pair, and a single texture atlas to be created for the textures. First, two atlases were created, this I think I've found why (there's a maximum size and a margin is used to make sure the image doesn't bleed to the other side). I'll try to tweak the settings to get what I want in this case. But there are two other problems in the result: 1. there are 4 geodes and 4 geometry instead of 1 and 1. 2. it didn't include two of the textures in the atlas. I can't figure out from the code why it's not merging all the geodes and geometry together, and why it's not including two textures in the atlas. In the model itself, nothing really sticks out as being different between the geodes/geometry that were merged and those that weren't (and ditto for the textures that were included in the atlas and those that weren't). Are there any guidelines to make sure the result is optimal? Or are there criteria I should know about to be able to get the results I want (other than dataVariance)?

Re: [osg-users] Using TerrainManipulator when the projection matrix is in Ortho mode
Hi David, I'm experimenting using the a scene graph projected in Ortho mode using the setProjectionMatrixAsOrtho function on the camera and while using the TerrainManipulator on the camera I noticed that the pan is working, but zoom is not! In fact, the only way that I could affect any kind of zoom was to narrow the POV on the camera (that realty is not a zoom). Well in fact yes... Zoom, in camera-speak, is making the FOV of the camera smaller/larger. What the normal manipulators do to zoom is to move the camera itself, i.e. dolly in/out in camera-speak. You may have seen the dolly in zoom out effect in movies, where the camera dollies in while doing a zoom out with the lens at the same time, and I use that expression to help me remember the difference between the two. http://en.wikipedia.org/wiki/Dolly_zoom http://en.wikipedia.org/wiki/File:Contra-zoom_aka_dolly_zoom_animation.gif But to get back to your question, this is an FAQ... Since with an ortho camera moving the camera forward or back will have no visible effect (apart from when you start hitting your near/far planes), you won't be able to zoom with the normal camera manipulators in an ortho view. You will have to make your own manipulator or use another way of changing the camera's left/right and top/bottom clipping planes, effectively the camera's field of view (though in ortho it's not a frustum, but a box). I kind of wish (and I've expressed this wish in threads that asked the same question before, but haven't had time to do anything about it) that the OSG camera manipulators supported affecting other parameters of the camera than just its view matrix. As it is, you'll have to affect the projection matrix yourself directly, i.e. your camera manipulator will have to know about the camera(s) it's affecting, which defeats the nice loose coupling that we have between camera manipulator and camera otherwise.

A zoom lens on a camera changes the FOV to make the image larger or smaller.

The last element of a projection matrix tells you if it's perspective or ortho - mat[3][3] will be 0 or 1 respectively (see http://www.songho.ca/opengl/gl_projectionmatrix.html). So you can have a single camera manipulator that works for any camera (for both projection types), and decide what to do depending on that value if you want. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] runtime error
Hi, remove the openthreads packages using package manager as well. If that doesn't work, please post the output of: ldd osgversion on both machines jp On 05/01/11 03:29, Michael W.

I just removed the osg package with package manager and then got the latest trunk on both machines. I build fine and they install fine on each platform. However, I get the same result. I get the error when I build osg from source and I can run osgversion when I install 2.8.1 from the package manager.

Re: [osg-users] Using TerrainManipulator when the projection matrix is in Ortho mode
Hi,
I've made an ortho texture manipulator before for panning and zooming an
image. Basically you have to scale the ortho projection before doing any
translation/rotation.
osg::Matrixd OrthoTextureManipulator::getInverseMatrix() const
{
return osg::Matrixd::translate(-_center) *
osg::Matrixd::translate(-_zoom_offset) *
osg::Matrixd::scale(_distance, _distance, 1.0) *
osg::Matrixd::translate(_zoom_offset) *
osg::Matrixd::rotate(_rotation.inverse());
}
This was for a texture in the XY-plane.

Frankly I've never had the chance to look into the logistics of it yet! I just

never done anything Orthographic in OSG (outside of a Hud display) before.
Thanks for the help!

Re: [osg-users] Limitation in current ImageLayer serializer
Hi,
I have found a little more time to work on this issue but have become stuck.
Using a user serializer I have managed to read and write the image sucsessfully
in the case that the image is loaded, but cant get it to work in the case the
image should not be loaded. I think the issue is that, when I don't want want
to read the image (i.e. deffered loading is enabled), then I still need to read
the image 'header' from the stream. If the image is embedded in the file then I
think I will need to read the entire image regardless of wether deffered
loading is enabled or not (I haven't looked at this case yet).
The code I am using is (I am testing with .osgt files so far):
static bool readImage( osgDB::InputStream is, osgTerrain::ImageLayer im )
{
std::string filename = im.getFileName();
if (!filename.empty())
{
bool hasImage;
is hasImage;
if(hasImage) {
is osgDB::BEGIN_BRACKET;
bool deferExternalLayerLoading =
osgTerrain::TerrainTile::getTileLoadedCallback().valid() ?
osgTerrain::TerrainTile::getTileLoadedCallback()-deferExternalLayerLoading() :
false;
if (!deferExternalLayerLoading)
{
osg::ref_ptrosg::Image image = is.readImage();
if (image.valid())
{
im.setImage(image.get());
}
} else {
//I think this is where I need to read of the image 'header'
}
is osgDB::END_BRACKET;
}
}
return true;
}
static bool writeImage( osgDB::OutputStream os, const osgTerrain::ImageLayer
im )
{
const osg::Image* value = im.getImage();
bool hasObject = (value!=NULL);
os hasObject;
if ( hasObject )
{
os osgDB::BEGIN_BRACKET std::endl;
os.writeImage( value );
os osgDB::END_BRACKET;
}
return true;
}
The relevenat section of the osgt file that is created is:
Layers 1 {
Object osgTerrain::ImageLayer {
UniqueID 9
Name kljhjkl
FileName earth_L1_X0_Y0_kljhjkl.dds
Locator TRUE {
osgTerrain::Locator {
UniqueID 4
}
}
Image TRUE {
UniqueID 10
FileName earth_L1_X0_Y0_kljhjkl.dds
WriteHint 2 2
DataVariance STATIC
}}
}
And the error I get when loading the file with deffered loading enabled is a
bad allocation error.
Any suggestions would be greatly appreciated!
Cheers,
Brad

Subject: Re: [osg-users] Limitation in current ImageLayer serializer
Hi Brad,
In fact when I'm working on the osgTerrain serializers, I don't pay
much attention to the special mechanism that may be required when
loading terrain tile and layer classes. For the case that the image
layer may be loaded inactive according to an additional flag, I
suggest that we should handle all of these with a user serializer
instead, that is,
REGISTER_OBJECT_WRAPPER( osgTerrain_ImageLayer,
new osgTerrain::ImageLayer,
osgTerrain::ImageLayer,
osg::Object osgTerrain::Layer
osgTerrain::ImageLayer )
{
ADD_USER_SERIALIZER( Image ); // _image
}
And write/read images and activate them by ourselves. Here we can read
out an image object from the input stream using is.readImage(), and
write image to disk files with the operator.
Hope this can help if you would like to help fix the problem. :-)
Cheers,
Wang Rui
2010/11/30 Brad Christiansen brad.christian...@thalesgroup.com.au:
Hi,
I have discovered a piece of missing functionality in the new serializer for
osgTerrain::ImageLayers. The issue is that all optional layers are loaded
when an osgb file is loaded regardless of weather they should be or not.
The relevant piece of code for the the .ive format is in (in osgDB_ive)
void ImageLayer::read(DataInputStream* in) at line 64:
bool deferExternalLayerLoading =
osgTerrain::TerrainTile::getTileLoadedCallback().valid() ?
osgTerrain::TerrainTile::getTileLoadedCallback()-deferExternalLayerLoading()
: false;
// Should we read image data from stream
IncludeImageMode includeImg = (IncludeImageMode)in-readChar();
if (includeImg==IMAGE_REFERENCE_FILE deferExternalLayerLoading)
{
setFileName(in-readString());
}
else
{
setImage(in-readImage(includeImg));
}
The new serializer simple adds an image serializer for an ImageLayer with no
similar checks.
I have had a quick look at coding a fix but have to admit I still dont fully
understand how the new system works in such cases. If anyone can give me some
pointers on how to go about adding this functionality that would be greatly
apprecaited as at the momment I am having to covert my terrain
