[REBOL] Re: Draw performance

Hi Davide,
Nice.
The number isn't as much of a problem as the window size, large faces give
View a hard time to keep refreshing.
One trick which works with some draw operations is to make sure the offset
of the main drawing area is at 0x0 or Origin 0x0, I have scripts here which
made the speed increase by doing this.
I took a different approach when I wrote my ballz.r script doing it with
multiple faces instead of using draw. It would be interesting to re-write
using draw, but I think draw would be slower because it would need to
interpret the block each time.
If you want to grab ballz.r it is at

You will need to download the subdirectory with gfx too. Apologies that they
is no autodownload for this, but I wrote the script for IOS where that
wasn't needed. When you run it hit the "+" a few times to see how fast it
can get.
Cheers,
Allen K
