Hi,
if anyone needs a workaround here is what I did (normalizing the mouse movement
myself):
Code:
bool MapManipulator::performMovementLeftMouseButton( const double
eventTimeDelta, const double dx, const double dy )
{
if (disableMovement){
return false;
}
float scale = viewMatrix.getScale()[0];
osg::Matrixd translation;
double viewportWidth = 1.0;
double viewportHeight = 1.0;
if (camera.valid()){
viewportWidth = camera->getViewport()->width();
viewportHeight = camera->getViewport()->height();
}
double normDx = 2 * (_ga_t0->getX() / viewportWidth - _ga_t1->getX() /
viewportWidth);
double normDy = 2 * (_ga_t0->getY() / viewportHeight - _ga_t1->getY() /
viewportHeight);
GuiLog(riff::DEBUG) << "x: " << _ga_t0->getX() << " xmin: " <<
_ga_t0->getXmin() << " xmax: " << viewportWidth;
viewMatrix = viewMatrix *
translation.translate(-scale*normDx*viewportWidth,
-scale*normDy*viewportHeight, 0);
double desiredAlt =
altitudoMeter.calculateAltitude(viewMatrix.getTrans()[0],
viewMatrix.getTrans()[1]) + scaleToAltitude(scale);
viewMatrix = viewMatrix *
translation.translate(0,0,desiredAlt-viewMatrix.getTrans()[2]);
isFollowing = false;
return true;
}
Thank you!
Cheers,
Łukasz
