Hello All,
As I'm investigating on which drawing techniques to use for a
software I'm planing to create,
imagine a kind of vector drawing program (that's not really that but
a somewhat similar).
In its actual version, all drawing relies on NSBezierPath/Quartz
primitives and is really fast.
Now, I'd like to use CALayers and CoreAnimation extensively, so my
questions are the following:
- Should I take care of not using too much Layers like with NSView
(currently I have 1 view that draws all). By too much, in the worst
case scenario I could use tens of thousands of layers (or more!)
(actually ~one per object drawn)
- Is there a performance slowdown if I use too many of them?
- Would it take quite a lot of memory?
- etc.
Regards.
