13:13:50_deathphoe: the one with copy-seq.. why not allocate all the frames in the beginning and just write to each one
13:14:16phoebecause frame N depends on all frames that were before, so 1..N-1
13:14:57phoeso it's logical to me that for drawing frame N, I will want the result of drawing frame N-1, which depends on result of drawing frame N-2, ..., all up to frame 1
13:15:19phoeso it's logical to me to draw everything on one frame and then just collect their copies as results.
13:15:42_deathso you pass the previous frame and merge the two data into a new frame
13:16:12phoecould do, sure thing - except I don't see any obvious optimizations here, sans for saving one frame's worth of memory
13:17:47_deathit should be much faster.. I've been doing image-related stuff w/ Lisp for some years :)
13:19:38phoeshould be? why would allocating N images from the start and writing to them be much faster than copying an array N times after writing to it?
16:02:38fiddlerwoaroofdxtr: the other thing that might be happening is that you're looking at the *inferior-lisp* buffer instead of the *slime-repl sbcl* buffer
16:02:58fiddlerwoaroofmy inferior-lisp just has the * prompt.
