Hello OSG-Users, (I'm writing a display application, using osgviewerQt)
I'm looking for a way to check, whether I need to redraw the scene to skip a redraw, if would be the same as the previous (fixed image). Or is this already done by osg-library? I figured, I only need a redraw, if a) Camera changes (position, field of view) b) scene changes (geometry changes, color changes) Unfortunately my first guesses and web searches were not successful, e.g. I saved the cameras ViewMatrix ( getCamera()->getViewMatrix() ) after a call of frame() to compare it to the current before the next call of frame(). Oddly the seem to change every time, even though the Viewer showed a fixed image. Can anyone point me to a direction and offer hints, to how I can achieve this? Am I carrying coals to Newcastle, since OSG would already be doing this and/or I only forgot to set a flag? Thanks in advance and sunny greetings Hartmut -- frag nicht - du könntest eine antwort erhalten NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!
