I would like to set zoom mouse control in rgl in order to redraw the map with
more or less details depending of the zoom coefficient (such as google maps or
openstreetmap do).
I already tried the rgl.setMouseCallbacks(button, begin = NULL, update = NULL,
end = NULL) function but this function do not seem to work with trackball
(only left, middle and right click).
Thus the question is :is it possible to modify trackball function using rgl ?
Thank for your help
