What about the performance ?
Imagine a simple gauge with a background and a needle. This could be
drawn with
3 lines of Nasal code:
DrawTexture(background, x,y),
Rotate(angle),
Drawtexture(nnedle, x,y)
So it can't be slower than xml gauges.
And more complex gauges ? This is were draw to texture is handy. There
is no
need to generate the texture every frame. Some instruments need to be
refreshed every 1/10
of second, perhaps a radar could use a refresh of half a second, and a
moving map a
refresh every second (or less).
Now the xml gauges wont refer to a texture loaded from a file but to
this generated texture.
Harald.
