Re: [osg-users] Using 'NodeTrackerManipulator' while holding camera steady

The osgmanipulators example is very clear. I should have checked the examples first! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=73606#73606 ___ osg-users mailing list

Hi, I think this issue was commented somewhere else, but I couldn't find it again: there is something broken with the cloning of osgDB::Options. This minimal working example works fine with 3.4.x, but SIGSEVs with 3.6.1-rc3 and current master: #include int main(){ auto globalopts = new

Re: [osg-users] Can a FrameBufferObject be shared by multiple cameras?

Hi Robert and Glenn, I struggle against this problem too for a will now.. Wouldn't it be a good design to make FBO a Camera property and RenderStage take this one if exist for its stuff? Cheers robertosfield wrote: > Hi Glenn, > > If there is a way to share FBO's between osg::Camera I don't

Re: [osg-users] Setting OpenGL and graphics card settings prgrammatically?

Hi, AFAIK there is also a https://developer.nvidia.com/nvapi library. Unfortunately I have no personal experience with this but I believe it can be used to prgramatically override the setings usually set with NVidia Control Panel. Cheers, Wojtek 2018-05-10 20:18 GMT+02:00 Daniel Emminizer,

Re: [osg-users] Setting OpenGL and graphics card settings prgrammatically?

Hi Chris, Not sure if this is what you’re looking for, but you can give a hint to the drivers by exporting variables in your code. In my main.cpp I do something like: #ifdef WIN32 extern "C" { /// Declare this variable in public to enable the NVidia side of Optimus -

[osg-users] Setting OpenGL and graphics card settings prgrammatically?

As you are aware, drivers like the NVidia Windows driver have a variety of tuneable settings accessible through the vendor-specific setting application. Many times these accomplish things that can't be accessed through the standard OpenGL APIs or extensions. Is there any way to force settings

Hi Robert, I got my build on Linux done. I test both GLCORE configuration and non-GLCORE configuration on OpenSceneGraph-3.6. I am seeing the error in all 3 configurations: 1) Linux Ubuntu 14.04; default OSG 3.6 branch build (GL compatibility mode); NVidia Quadro K1000M GL 4.5, 384.11

Hi Mark, I am trying to work out why you have the build problem. Is there a chance you've done an in source build previously that set the include/osg/GL prior the OSG_GL_CONTEXT was added, then you're out of source build is not overriding this as the out of date in source version of

Hi Robert, Thanks for trying the example. I'm perplexed why it's OK for you but not me. In case you're curious, I'm attaching the screenshots of the output. I should note again that I am running with OPENGL_PROFILE="GLCORE" / GL3 mode. Would that make a difference? I will rebuild

Hi Dan, I finally had a chance to look at the your example. It works the same under 3.6 branch and 3.4 branch for me, I don't ever see any issues with the texture become skewed regardless of the size of the window. Robert. On 7 May 2018 at 12:15, Daniel Emminizer, Code 5773

Re: [osg-users] Can a FrameBufferObject be shared by multiple cameras?

Hi Glenn, If there is a way to share FBO's between osg::Camera I don't know of it off the top of my head. You'd need to look at the src/osgUtil/RenderStage.cpp so see how it sets up the FBO's. It's able to ruse it's own FBO on subsequent frames so there may be a way for forcing it to use an

[osg-users] Can a FrameBufferObject be shared by multiple cameras?

Hi Robert, I have a scenario that uses multiple RTT cameras. (The approach is similar in concept to CSM - Cascading Shadow Maps - where you compose a texture using multiple frustums). Each RTT camera renders to a different layer of a Texture2DArray. This works great! However, it uses a lot more

Robert, Could you do me a favor and see if the example in the OpenSceneGraph 3 Cookbook, page 242 works on your computer? I was originally wanting to test with that but when I get totally white on the left side of the screen (when it should have been showing the depth buffer), I went to
