Re: [osg-users] (no subject)

Hi Anders, There is a new mechanism for managing clean up of GL objects, which in theory should help improve management of lifetimes of GL objects. The warning suggests that something is try to do GL call after the context is cleaned up, I don't know yet if this is a bug in the new code or

Re: [osg-users] Changes in osgVolume from 3.0 to 3.4

Hi Alex, The blending difference might be down to a bug fix elsewhere in the OSG. Have a look at yesterdays discussion "osgViewer/Renderer ctor set wrong defaults for SceneView", in particular my replies that explain how a bug fix (in OSG-3.2 onwards) to the way that global State is managed

Re: [osg-users] (no subject)

Yep sorry. I was having some (other) issue where text was not rendered when I had enabled shadows, so I was messing with osgViewer.cpp copying sample code from osgShadow there. The example that reveals the issue at shutdown is plainly osgShadow.cpp Output: osgshadow.exe --window 0 0 1024 768

Re: [osg-users] Viewing Stacked Semi-Transparent Geodes

There are techniques to perform order independent transparent rendering, one of these is demonstrated in the osgoit example of OpenSceneGraph. However osgoit uses a multipass technique and can be rather slow. Christian 2016-02-04 9:31 GMT+01:00 Voerman, L. : > Hi Erik, > the

Re: [osg-users] Changing indexing at runtime

Hi Roberto, if you have the Geometry pointer somewhere you can change the attached primitive sets as long as you are doing this during update only and set its state to dirty. Cheers Sebastian Hi, at runtime, i need to switch the DrawElementsUInt array attached to geometry with another

[osg-users] Mesh reduction with indexes modification

Hi, I'm using osg for reproduce SRTM data into a scene and all works fine. Now i want to reduce triangle in the scene by maintaining same vertex array and modify index buffer in order to skip some of the vertices in vertex array. I use indexed GL_TRIANGLES. This is the code i use for indexing

Re: [osg-users] (no subject)

Seems that this actually caused a lot more problem than I first thought... The fact that you need to have a valid reference while tearing down nodes, means that our system with plugins (dll:s loaded etc) now causes problems. The Camera it self, has references to a scene, states, (Renderer) etc,

[osg-users] (no subject)

Hi all. Trying OSG 3.5.1 and I have started to get some problems with objects (osg::Program/osg::Shaders etc.) being de-allocated after context is destroyed: Error: OpenGL version test failed, requires valid graphics context. Sometime it crasches sometimes it just print the warning. I can

Re: [osg-users] FBO and Renderbuffer leak in OSG 3.5

Hi Robert, The leak is only noticable when you frequently remove and re-create cameras, something that osgprerender does not do. I've added an osg::Observer to test that the Camera is being deleted properly, and it is. It looks like CPU side everything is being deleted correctly, only on GPU

Re: [osg-users] FBO and Renderbuffer leak in OSG 3.5

One more thing, it does look like an FBO specific issue, because if I run with ./osgprerender --window there is no leak whatsoever. Thanks, Jannik -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=66210#66210

Re: [osg-users] Viewing Stacked Semi-Transparent Geodes

Thank you for your response. In the interest of full documentation, I thought I should note that I tried setting the blend function as osgoit does, but it didn't make a difference in my example. Thanks anyway! cbuchner1 wrote: > There are techniques to perform order independent transparent

[osg-users] FBO and Renderbuffer leak in OSG 3.5

Hi, I have just tracked down a memory leak regarding FBO's to what appears to be an OSG bug. Please check out the attached screenshot of gDebugger, OSG attempts to glDeleteFramebuffers / glDeleteRenderbuffers from the main thread with no context current. That can't work properly and I'm

Hi Jannik, Does the issue appear with any of the RTT example i.e. osgprerender? >From your description it could be removing the FBO Camera from the scene graph but keeping a reference around for it beyond the lifetime of the graphics window that could be an issue. However, I suspect it isn't

Re: [osg-users] Viewing Stacked Semi-Transparent Geodes

Hi Erik, the effect you see is caused by your blend function being order dependent, for a good result transparent triangles need to be drawn back to front. Did you set the rendering_hint to TRANSPARENT_BIN (binNumber 10 / binName DepthSortedBin)? like in
