Hi all,I??m just rendering a simple Cylinder. It??s code as following. I
repeated load it 10 times.
osg::ref_ptr<osg::TessellationHints> hints = new osg::TessellationHints;
hints->setDetailRatio(100.0f);
geode->addDrawable(new osg::ShapeDrawable(new osg::Cylinder(osg::Vec3(6.0f,
0.0f, 0.0f), _radius, _height), hints));
when I first push ??s?? ,the frame of the scene is about 60Hz and then I
countinue push ??s??, the frame would drop to 40Hz, finally I push ??s??, the
frame just is 20Hz.
The sum cost time of event update cull draw and gpu is about 14.5ms(62Hz),not
the same as above 20Hz, I don??t know why? Could anyone give me some advice?
Best wishes!
Judy
