Hello,
I have been away for a while and happily spent several weeks without any
computers, but at the and i had to come back to reality...
I am still playing with graphics and am curious if there's any way
animations can be displayed using double buffering with plan9?
What I have done is a simple rectangle that changes size and generaly bumps
in the corners of the window. The effect is that on my ATI video card, the
refresh is not perfect, even if I have quite a delay between the redraws --
there's still some flicker.
Has there been anything done to enable displaying higher refresh rate image
under plan9 (i.e. animations)? If yes, how would one accomplish that?
The way I have implemented it is by simply changing the coordinates of a
rectangle, redrawing the screen with default color and drawing on top of it.
I'd be happy to see if anyone else has done anything requiring more than
10-24 refreshes a second...
Please bare with my silly questions, having in mind that I'm still learning
:)
