[osg-users] [vpb] Correct way to get texture data from USGS or any other source?
Hello! I try to build map using vpb in ECEF. According to manuals i've read it needs to start: vpbmaster --geocentric -t texture_file -o output_file So, clearly i need georeferenced texture file. On that page: http://www.osgvisual.org/projects/osgvisual/wiki/OsgTerrainData there is a bunch of links to get data. Since --geocentric option allows not to use elevation data, then only textures are needed. And here is a problem: i can't get georeferenced textures from USGS. All files i choose from different sets there are without georeferenced information. gdalinfo output: c:\Terrain\1_42822\FL\2007\200701_bay_county_fl_1ft_sp_clr\vol001gdalinfo 42822.tif Driver: GTiff/GeoTIFF Files: 42822.tif 42822.tfw Size is 5000, 5000 Coordinate System is: LOCAL_CS[unnamed, UNIT[US survey foot,0.3048006096012192, AUTHORITY[EPSG,9003]]] Origin = (1655000.3300010,574999.511) Pixel Size = (1.000,-1.000) Metadata: AREA_OR_POINT=Area TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch) TIFFTAG_XRESOLUTION=1 TIFFTAG_YRESOLUTION=1 Image Structure Metadata: INTERLEAVE=PIXEL Corner Coordinates: Upper Left ( 1655000.330, 574999.510) Lower Left ( 1655000.330, 56.510) Upper Right ( 166.330, 574999.510) Lower Right ( 166.330, 56.510) Center ( 1657500.330, 572499.510) Band 1 Block=5000x1 Type=Byte, ColorInterp=Red Overviews: 1024x1024 Band 2 Block=5000x1 Type=Byte, ColorInterp=Green Overviews: 1024x1024 Band 3 Block=5000x1 Type=Byte, ColorInterp=Blue Overviews: 1024x1024 gdalwarp output: c:\Terrain\1_42822\FL\2007\200701_bay_county_fl_1ft_sp_clr\vol001gdalwarp -t_srs +proj=longlat +ellps=WGS84 42822.tif 42822_conv.tif ERROR 1: No PROJ.4 translation for source SRS, coordinate transformation initialization has failed.

[osg-users] how to insert a QWidgetImage in a osgWidget::Window?
Hi all, I would like to show a Qt widget in a 3D viewer. I would like to drag it around, scale it and interact with it. I looked at the osgQtWidgets example but didn't find exactly what I need. Since I already implemented objects that are osgWidget::Window, I thought to add the geometry got from osg::createTexturedQuadGeometry() to the osgWidget::Window geode. So I created a Texture2D object and set to the osgWidget::Window with setTextureAttributeAndModes(0, texture). I also set an InteractiveImageHandler as cull callback. The problem is that I can't see the image. For testing I set an image loaded from file to the texture object and it works fine. So what is missing in my code to see the Qt widget image? Code: osg::ref_ptrosgWidget::Window window = new osgWidget::Canvas; float x = 0.0; float y = 0.0; float width = widget-size().width(); float height = widget-size().height(); osg::ref_ptrosg::Texture2D texture = new osg::Texture2D; osg::ref_ptrosg::Geometry quad; //std::string imageFile = C:/Users/User/Desktop/test.jpg; //osg::ref_ptrosg::Image image = osgDB::readImageFile(imageFile); //texture-setImage(image.get()); osg::ref_ptrosgQt::QWidgetImage widgetImage = new osgQt::QWidgetImage(widget); texture-setImage(widgetImage.get()); quad = osg::createTexturedQuadGeometry(osg::Vec3(x, y,0.0f),//center osg::Vec3(width,0.0f,0.0f),//width osg::Vec3(0.0f,height,0.0) );//height osg::StateSet* stateset = quad-getOrCreateStateSet(); stateset-setTextureAttributeAndModes(0, texture.get()); stateset-setRenderBinDetails(1, DepthSortedBin, osg::StateSet::OVERRIDE_RENDERBIN_DETAILS); osgViewer::InteractiveImageHandler* handler = new osgViewer::InteractiveImageHandler(widgetImage.get()); quad-setCullCallback(handler); window-getGeode()-addDrawable(quad); Regards, Gianni -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63994#63994 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

You might be doing things correctly and there is a bug that is

Could you create/modify and example to illustrate this crash?

[osg-users] Crash in Camera::setRenderer()
Hello everyone. In my application I create several views and several cameras. Upon user interaction each camera can be added or removed from a view using View::addSlave() and View::removeSlave(). My code ensures that each camera is only assigned to only one view at a time. A camera can't be assigned to another view before being removed from the view it currently is. When I do that I often get a crash in the Camera::setRenderer() method that is called by addSlave(). The crash happen into GraphicsOperation destructor. When a camera is added to a view with addSlave() a new renderer is created for it. If the camera already has a renderer that renderer is automatically deleted by the reference counting pointer. That's when the crash happen. It looks like the renderer (or maybe one of its members) is deleted twice. I'm not using multithreading. I don't change camera assignation during rendering with callbacks. Camera assignation is all done outside of the CompositeViewer::frame() method. Do you have any idea what might be causing this crash ?

Re: [osg-users] Ready to tag OpenSceneGraph-3.3.8 dev release, please test
Hi Jannik, Release build, Ubuntu 14.04 64 bit, g++ 4.8.2 In 3.2, the Update phase for this change takes 0.15ms. In svn/trunk, it's 1 ms. That's a factor 6 performance regression for the base cost of node callbacks. I have introduced Object::asNode(), asNodeVisitor(), asStateAttribute() and asUniform() to Object base class, and usage of this in Callback.cpp to replace dynamic_cast usage. With a tweaked version of your modified example and 100,000 callbacks I'm getting slightly over 3x speed up, based on frame rate. One thing to be wary of with these tests is what happens with the CPU frequency as powersaving can play havoc with accurate timing. What was the rationale for unifying all callbacks under a common base class? It enables scripting integration, where the script can provide a callback from the script itself without need for hardwiring to different types of callbacks.

Re: [osg-users] [vpb] Correct way to get texture data from USGS or any other source?
Hello! I totally agree with Sebastian. These data is surely geo-referenced, as I myself often used in the past data from USGS. Locking at the metadata you provided I would say that you are in an EPSG:2238 Lambert Conformal Conic projection, which is the main projection system for north Florida. You may try to specify to GDAL the source projection using this EPSG code.

Hi Robert and Rafa, I just see this change was introduced by Christian Kehl ( http://comments.gmane.org/gmane.comp.graphics.openscenegraph.cvs/12859) but probably he had a little mess in his computer when doing this change (As he also stated later ). It is possible it might be not necessary. Maybe Christian can comment something.

For macosx everything worked so far but for android I'm getting this error using the toolchain: osg-trunk/include/osg/GLDefines:35:21: error: conflicting declaration 'typedef GLfloat GLdouble' I suspect this is the same problem others has spotted. I think you suggested to do a better identification in cmake, or maybe just check if the symbol already exists in that header. I'll try to provide a fix later today. Regards, Rafa.

My intention was to introduce the same technique as osg::Node::asTransform() to avoid the dynamic cast, but only do this if there was a noticeable performance regression. The 20% regression you've seen could qualify. Is this with a release build? As general note, I suspect you are over using callbacks.

However, I did notice a performance decrease in the Update phase of about 20%, compared to OSG 3.2.0. This had me a bit concerned, so I digged through the changes and found commit https://github.com/openscenegraph/osg/commit/e967420323bb6e500425144cb305cf8060c1c515 . Since that commit, we now get *four* dynamic_cast's per frame and NodeCallback, which I suspect is causing the slowdown. Two dynamic_cast's are in NodeCallback::run, then another two in NodeCallback::traverse. Changing to the non-deprecated Callback instead of NodeCallback gives a slight improvement with now just two dynamic_cast's in Callback::traverse, but still isn't optimal. Ideally, the application should be able to decide on the level of safety vs. level of performance it needs. If a Callback is only intended to be used on Nodes, there is little point in dynamic_casting to Node every frame. I think I can workaround the casts by using a custom class derived from osg::Callback as the base class for all my node callbacks. Still, it's quite a peculiar situation that does affect all users of the OSG. I guess my question comes down to, are there any plans on optimizing the Callback code before a final 3.4 release? If you aren't convinced, I can throw together a repro case and some profiling data, but I think the impact of 4 dynamic_cast's per frame and NodeCallback should be obvious.

[osg-users] osgvolume: Swap technique in a VolumeScene fails
Hi, First, excuse the lack of details of the further, i haven't been able to debug enough to understand where the bug is... So, I tried a simple scenario with the osgvolume::MultipassTechnique: I initialize the volume rendering with MultipassTechnique (as in the example) And at runtime I change it to a new osgvolume::MultipassTechnique It yields a weird crash in MultipassTechnique::computeRenderingMode() with _volumetile==NULL ...?! So far I've debugged a lot but haven't been able to locate where that happen Any info would been welcome Thank you in advance Have a good day!

Hi Robert, I've just did an svn update and the error in android is still there. If we remove the line 35 ( typedef GLfloat GLdouble; ) of GLDefines file then builds ok. And it does not affect to macosx build, and probably won't affect to other desktop environments.

Re: [osg-users] [vpb] Correct way to get texture data from USGS or any other source?
Hello! Thanks for quick reply, it helped to solve a problem. SMesserschmidt wrote: Am 09.06.2015 um 11:35 schrieb Elias Tarasov: Hello! I try to build map using vpb in ECEF. According to manuals i've read it needs to start: vpbmaster --geocentric -t texture_file -o output_file So, clearly i need georeferenced texture file. On that page: http://www.osgvisual.org/projects/osgvisual/wiki/OsgTerrainData there is a bunch of links to get data. Since --geocentric option allows not to use elevation data, then only textures are needed. Who told you this? Of course you can use elevation data in geocentric mode ... Simply use -t for imagery and -d for digitial elevation data The book is called OpenSceneGraph 3 Cookbook Authors: Rui Wang Xuelei Qian Citation: To build databases in geographic coordinate, we can simply use the --geocentric option while executing vbpmaster. The complete command is: # vpbmaster -t data/TrueMarble.4km.10800x5400.tif --geocentric -o output/out.osgb Don't doubt the arguments we used this time. Yes, there is no -d option and thus no elevation map specified. As we have already indicated to use the geocentric system to build from the source, VPB will automatically use flat sea-level elevation data and construct the earth geometry according to the given GeoTiff imagery. And here is a problem: i can't get georeferenced textures from USGS. They are referenced, but in a non-supported coordinate frame. I never had problems of this kind yet. But there are definitively geo-referenced data-sets on USGS, as I'm using them myself. Yes, they are. Just in a different projection, it seems. Use LandSAT imagery, which is WGS84 projected, so there should no problems here. Actually, problems are exist.

Hello! Christian Schulte wrote: Hello! I totally agree with Sebastian. These data is surely geo-referenced, as I myself often used in the past data from USGS. Locking at the metadata you provided I would say that you are in an EPSG:2238 Lambert Conformal Conic projection, which is the main projection system for north Florida. You may try to specify to GDAL the source projection using this EPSG code. Regards, Christian Yes, it worked! However, i dont understand how did you figure out that projection is 2238. No such a number is presented into metadata. For a test, i also used EPGS:3857 and it seems to work similar. Thanks a lot! Elias.

Re: [osg-users] Crash in Camera::setRenderer()
Hi Nicolas, Are you using C pointers or ref_ptr when keeping reference around the to the slave Camera? If you use a C* pointer then there is good chance that the reference count on the Camera is going to zero when it's removed from the View and getting deleted, then you add that dangling pointer back to the View and bang your get a crash there after. That's my best guess given I don't have any code in front of me. Robert. On 9 June 2015 at 13:00, Nicolas Baillard nicolas.baill...@gmail.com wrote: Hello everyone. In my application I create several views and several cameras. Upon user interaction each camera can be added or removed from a view using View::addSlave() and View::removeSlave(). My code ensures that each camera is only assigned to only one view at a time. A camera can't be assigned to another view before being removed from the view it currently is. When I do that I often get a crash in the Camera::setRenderer() method that is called by addSlave(). The crash happen into GraphicsOperation destructor. When a camera is added to a view with addSlave() a new renderer is created for it. If the camera already has a renderer that renderer is automatically deleted by the reference counting pointer. That's when the crash happen. It looks like the renderer (or maybe one of its members) is deleted twice. I'm not using multithreading. I don't change camera assignation during rendering with callbacks. Camera assignation is all done outside of the CompositeViewer::frame() method.
