How can I hide this white geometry without using the color transparency method and intersect?

system win10&osg3.6.4

//Modifying the depth test sequence doesn't seem to work

setRenderBinDetails(1001,"DepthSorteBin");

There isn't any specific advice we can provide as you've provided no specific information about the problem bit of your scene graph, all we have is a screen shot with a random white quad circled. 

The best I can suggest is to look at your database in a modelling tool and remove the offending bit of geometry/triangles.  That assumes the problem is with some geometry in your scene.

However, you don't provide any information that we can use so my suggestion is just a random guess as to what might be wrong.  You really have to try and provide a clear explanation of what is your scene graph and where the problem might be in this scene graph.

Thank you for your question and answer. The problem has been solved.I work in a closed environment.Cannot provide code.

I would like to ask how to solve the problem that after OSG thread rendering, when the UI thread display will cause thread lag.

void osgQOpenGLWidget::paintGL()

{

OpenThreads::ScopedReadLock locker(_osgMutex);

if (_isFirstFrame) {

_isFirstFrame = false;

m_renderer->getCamera()->getGraphicsContext()->setDefaultFboId(defaultFramebufferObject());

}

m_renderer->frame();

}
