I'm trying out the projection code from s65's project to see if an iso projection is more efficient than a perspective one. It looks promising but the flicker is awful when running from within scratch, so I'm uploading to try it in a web page and see if the flicker is any less there - it certainly was for the original project that looked very smooth until I downloaded it... OK, no flicker, but is the speed fast enough to draw 3 ships of over 20 vectors each?
