I'm wondering what a proper abstraction would be

this article looks promising: https://research.cs.wisc.edu/graphics/Courses/838-s2002/Papers/polar-decomp.pdf

Good morning everyone!

for interpolating transformation matrices

I'll be online in 1h or so

jackdaniel: We really should fix the fact that transforms don't affect pixmaps
8:18:39
loke
It should be reasonably easy to fix, too
8:18:50
loke
Would you like me to tackle that one?
9:32:22
jackdaniel
wouldn't that be a costful operation? each individual pixel will need to be transformed…
9:34:09
loke
jackdaniel: Yes. Well, it can be accelerated using Xrender, I think
9:35:01
loke
Even without xrender, it wouldn't be too bad, I think.

Doesn't Opticl have that functionality?
9:52:19
loke
beach: Hmm, I recall looking at it and determining it didn't.
9:52:22
loke
I could be wrong though
9:52:40
loke
But with xrender it should be really fast
9:53:07
loke
A pure Lisp version would be needed with clim-fb though
10:07:00
loke
beach: That's OK. I'l just interpret that as “good morning”

Maybe I'll try changing my keyboard.

I'm giving up on the attempt to create a generic double buffering (for now)

loke what functionality are you looking for in opticl?
14:44:32
beach
Transforming pixmaps I think.
14:45:16
slyrus1
opticl:transform-image ?
14:46:31
slyrus1
loke: let me know if you're looking for something else (there's also transform-coord but that may not be exported -- but could be, of course).
