[osg-users] missing color for simple model with GLCORE

Hi, i'm trying to get a model with colors and GLCORE (in OSG 3.6.2). If i build OSG with the standard build options using GL2 the model shows some color (see osg_gl2.png). When i buildOSG with GLCORE the load does not show any colors (see osg_glcore.png). The model does not contain any texture

Re: [osg-users] handling of #pragma line in Shader::_computeShaderDefines()

Hi Robert, i'm using OSG version 3.4, but i checked in OSG 3.5 the same code is used. In osgEarth the #pragma is used as a tag only. The shader compositioning is done by osgEarth itself. Thank you! Cheers, Andreas -- Read this topic online here: http://forum.openscenegraph.or

Re: [osg-users] handling of #pragma line in Shader::_computeShaderDefines()

Sorry for the confusion. The shader is from osgEarth https://github.com/gwaldron/osgearth/blob/master/src/osgEarthDrivers/sky_simple/SimpleSky.Ground.ONeil.vert.glsl. My problem with the _computeShaderDefines() function is that it tries to parse a #pragma line, but in the end is actually parses

[osg-users] handling of #pragma line in Shader::_computeShaderDefines()

Hi, I stumbled upon the Shader::_computeShaderDefines() function, which as far as i could understand should extract additional information from all line starting with #pragma. When a line is found it looks for the next opening brackets and analyze the text between the #pragma and the opening br

Re: [osg-users] StatsHandler missing numbers

Hi, I stumbled across the same issue and i found the trigger for this issue. The font resolution is the trigger for this issue. I did some testing and found that: - using 64 the text disappears completely - using 32 (the default) results in some missing or wrongfully colored characters - using

Re: [osg-users] Threading issue in ObjectWrapper

Hi, I'm using a slightly modified version of OSG 3.2. But i've just checked the latest version (trunk/master) and i haven't seen any changes which should solve this issue in the latest version. Cheers, Andreas -- Read this topic online here: http://forum.openscenegraph.org/vie

[osg-users] Threading issue in ObjectWrapper

Hi, I came across an issue in the ObjectWrapper::findWrapper (trunk). - application starts, list of object wrappers is empty - two nodes are loaded simultaneously by two database pager threads - both nodes require the same object wrapper - one of the two threads loads the appropriate serializer wh

Re: [osg-users] Serializer trouble with TextureAttributeList

Hi, i found the cause of this issue! When i run 'osgviewer cow.osgx' but the reflect.rgb (referenced as Images/reflect.rgb) file is not in the same directory as cow.osgx the read errors occur. If i put the image file into the directory loading works fine. IMHO loading of the osgx file should co

Re: [osg-users] Serializer trouble with TextureAttributeList

Thanks for the zip-file! I compared you cow.osgx against mine and haven't found any differences except the filename. So i conclude that the file writing isn't faulty only the reading part causes the trouble. Now i need to dig a bit deeper to find the caused of this :| @Robert: Are u using 32 o

Re: [osg-users] Serializer trouble with TextureAttributeList

Hi, i just checked out revision 14442 from http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk and build it cleanly on my Kubuntu 14.04 machine. This time i used the original OSG source tree without any modification and using all 3rd party libs from the system. When i run osgconv on cow.osg

Re: [osg-users] Serializer trouble with TextureAttributeList

Thanks for checking this issue! I suppose that some kind of compile/cmake options/define is somewhat wrong since i'm using a modified version of the OSG cmake build system. Now since i know that the OSG code is correct i need to investigate on my machine further. BTW I don't think it's an local

[osg-users] Serializer trouble with TextureAttributeList

Hi, I've upgrade to the latest OSG version (trunk from 9. Sept) and build it under Linux/Ubuntu 14.04 64-bit, but ran into some trouble when saving/loading nodes to osgt/osgx/osgb. I'm running Code: osgconv cow.osg cow.osgx without and warnings. Afterwards when i run Code: osgconv cow.osgx

Re: [osg-users] PolytopeIntersector "distance" and Transform

Hi, i tried to use the osgEarth::Picker class, which uses the PolytopeIntersector for picking and came across the same issue. I used Aurelien work-around and recalculate the distance, but as Aurelien already mentioned it's quite slow because of all the recalculation and sorting. Since Aurelien

[osg-users] Intersection of two lines

Hi, this maybe a stupid and simple question. I have two lines and i want to calculate the intersection point of the two lines. For both lines is have a starting point and the direction. Is there a function to calculate the intersection point? Thank you! Cheers, Andreas -- Read

Re: [osg-users] turn off stereo in osgQt

Hi, i figured out what was wrong with the Qt viewer. The problem with the viewerQt was simple that all created cameras do not have a draw buffer assigned. They will use GL_NONE, which causes the trouble. When i set the draw buffer to GL_BACK everything works fine. Cheers, Andreas

[osg-users] turn off stereo in osgQt

Hi, i used the osgviewerQt example with the following modifications: - added a toggle stereo on/off event handler - added traits->quadBufferStereo = true; when creating the graphic context When i start the program with OSG_STEREO=ON and OSG_STEREO_MODE=QUAD_BUFFER the program works as expected. B

[osg-users] osgText::Text change size during culling

Hi, I want to create a billboard with an icon and a text. I noticed that it cannot use SCREEN_COORDS, when i use my own Billboard. It don't want the text to rotate to screen, i just want the scale-to-screen functionality. To accomplish that i tried to set the character size during the update pa

Re: [osg-users] Enable/Disable stereo during runtime

Hi, If i set Code: traits->quadBufferStereo = true; on my test system without a stereo hardware createGraphicsContext fails. So i need to check before if a stereo hardware is available. I know that OpenGL reports some kind of stereo capability, but i don't know to i could get the OpenGL cap

Re: [osg-users] Enable/Disable stereo during runtime

Thank you Wang Rui! I haven't thought it would be so easy ;-) I use the quad buffer stereo mode. Do i have to create my graphic context with quad buffer enabled or can i turn it on later (during runtime)? Is there a draw back when quad buffer is enabled but stereo is not enabled (concerning per

Re: [osg-users] Enable/Disable stereo during runtime

Hi, i'm still trying to enable or disable stereo during runtime. I created a small app, which simply recreates the graphic context when you press g. It does not enable or disable stereo at all (due to lack of stereo hw at the moment), but i think the actual stereo on/off can be easily added when

Thanks Robert! I'm using quad buffer stereo and to enable or disable i have to create a new graphic context. At the moment i trying to recreate a graphic context using the following ops: - remove my osgViewer::View instance from my osgViewer::CompositeViewer instance - remove all osgGA event ha
