Hi Allan,
Do you want use the standard camera manipualators but with a set home
position, or are you looking for completely custom management of the
camera's view position? If you want the later than you'll want to not
bother with any camera manipualtor and just set the viewer's master
camera's on each frame i.e
while(!viewer.done())
{
viewer.getCamera()->setViewMatrixAsLookAt(eye, center, up);
viewer.frame();
}
Wheras to set the home position of camera manipulator you do:
viewer.getCameraManipulator()->setHomePosition(eye,center,up);
And then to move to the home position call:
viewer.home();
Robert.
