Re: [osg-users] Qt Quick and Android

Hi James, Thank you for suggestions. I don’t sure that using QQuickWindow::beforeRendering() or QQuickWindow::afterRendering() signal will help since it also uses same OpenGL context as Qt Quick Scene Graph, but I will try it. Solution that uses QQuickRender sound good, I will lock at

[osg-users] How to access the view parameters from which the Cull Visitor came?

Hi! I have a multi-view app (using CompositeViewer) in which some nodes should look differently in different views. For example, some label positions should be recalculated depending on the view's camera parameters and some annotations (rectangular area with a border some text) should be

Re: [osg-users] Frame rate improvement

Hi, thanks for the aswer. Yes, sure. I am running in release. It is a big scene: State Graphs: 2321 Fast Drawables: 14177 Primitive Sets: 52013 Vertices: 7215794 Triangles: 971664 Quads: 984448 Polygons: 362048 It is strange that Cull always go from 900ms to 300/400 ms doing nothing after

Re: [osg-users] Frame rate improvement

Hi Ale, Having many thousands of transform in the scene graph will be very expensive on cull performance as each transform require the view frustum, modelview and projection matrices and other cull paramters to be cloned and transformed into the local coordinate frame. Thosudans of transforms

Thanks for the suggestions, Robert! I was just investigating such possibilities, shows I'm on the right track... /Andreas On 2017-09-22 12:13, Robert Osfield wrote: Hi Andreas. On 22 September 2017 at 09:40, Andreas Ekstrand

Re: [osg-users] Frame rate improvement

897 ms culling time sounds excessive to me, even for a large scene. Is this application built in a release configuration of the compiler? You could attempt a hierarchical grouping of the scene graph nodes with group objects to speed up the culling, using some kind of space partitioning algorithm.

[osg-users] Frame rate improvement

Hi, until now I improved visualization performance of my application in several way thanks to your suggestions. Now I would like to go another step ahead. May be this is common topics but it is not clear to me how to solve it. I have a CAD-like application. Potentially a scene can contain

[osg-users] Running a per-frame task on the graphics thread

Hello, Related to my other post about integrations with QtQuick, to achieve optimal performance I need to run a task on the graphics thread with some very particular timings, and I’m hoping for some advice on the most compatible way to achieve that. Especially, I’d like a solution which is

Re: [osg-users] Cloning text

Hi, I'm using osgText to show vertex numbers. Often enough it's only 0,1,2 for triangles but it can be several hundred thousands of them. It's never been optimal, I know - and I guess this is the time to do something about it, I will look into an alternative way without osgText. Any

[osg-users] 3.4.1 bug in CMakeLists?

Hi list. I am not such an expert in CMake to say it for sure. In fact, I basically only know how to use it. Never did a sophisticated script myself. But it looks to me that some CMakeLists.txt in OSG v3.4.1 has a problem when building for MSVC in debug (and in my particular case in 64 bit
