[REBOL] Re: Draw performance

From: rebol:optushome:au at: 22-Jan-2003 17:06

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
