**Support / wrapping a ground plane.**

« **on:**December 20, 2013, 12:47:15 pm »

Is it possible to make a ground plane wrap back on itself. My plane is large but not large enough to hold all of my map at once. So I have to re build my vertex map when I move over 700 m to display the current modified plane.

It would be ideal if the right edge connected to the left edge like a cylinder and the bottom connected to the top.

So I would only need to update areas beyond the clipping range in the direction I am traveling. This is an old method to reduce the amount of processing needed to update a map/plane.

Eg if I am moving up the map I would update y max line then y max -1 then -2

Where the map is x*y .

If going right update xmin then xmin+1

For num vertical lines

if y goes thru 0 y =ymax

If x >xmax x=0

So we just update the Poly's in the direction of travel.

Other techniques???
