Graphics Performance (mostly Connectors 2.0)Michael Latta lattam at mac.comWed Dec 29 22:16:31 UTC 2004
At the bottom of this message is a MessageTally on dragging a shape
around with 8 connectors attached to it. These connectors have no
arrow heads, but spend a fair amount of time dealing with arrow heads.
Ned:
1) Is there some way to optimize this case?
2) Are you drawing an empty arrow on these cases, and spending time
building and possibly rotating an empty form, or a form with a short
line?
General:
1) I had to comment out the delay at the end of each interaction cycle.
While this does mean the CPU is running at 100%, Unix can handle that,
and even with high performance set it was taking 14%-30% in waiting on
that delay. With it disabled interaction is better, but still not
really keeping up with the mouse.
2) It appears that Balloon draws to a form and then BitBlt the form to
the screen. Is this correct? It is spending a fair amount of time
doing this copying of bits.
It looks like my next task it to think about line drawing and making
that faster. Optimizing arrow heads would also help. Any suggestions
on how to proceed would be appreciated. A similar app written in
Objective-C is about 2x faster / more responsive. The anti-alias of
lines as lines rather than curves should be faster, than the current
treatment. For those shapes that are not being moved, it should be
possible to cache the form that Balloon is creating. Would this work?
That could reduce the drawing time for larger diagrams. My test
diagram has 3 connectors not affected by the drag.
