so, i had this idead of a sort of scanner, for a top down project im making. the scanner would be located out of the screen, but it would project its content on screen. sounds simple, but.. is it possible to achieve a picture in picture? the reason why i thought of this was that i originally thought about having a zoom out option,which would be really simple and easy, but upon testing the performance takes a hit, because theres more stuff on screen when zoomed out. so, i thought this would serve a purpose, while not having to render all the needless stuff on screen around the player, just the area the player is "scanning".
anyway, i quickly threw an example pics together in gimp to better illustrate this idea im trying to achieve. heres the pics:
is the minimap object able to do something like this or do i need to resort in dark rituals to achieve this? <img src="smileys/smiley36.gif" border="0" align="middle">
or should i just take the potential performance hit and make the zoom out layer- trick instead? (im trying to save performance as much as i can this early on)
any advice would be appreciated!
