from documentation/opengl.html:
"The easiest way to make an OpenGL display is to subclass Fl_Gl_Window.
Your subclass must implement a draw() method which uses OpenGL calls to
draw the display.
Your main program should call redraw() when the display needs to change,
and (somewhat later) FLTK will call draw()."
I try do do a little 3d opengl animation with a sequence like:
To show a number of frames:
end=number of positions (frames)
counter=0;
while(counter<end)
{
do linear interpolation. %: (1/end) * counter;
do trasformations for position;
mywindow->redraw();
counter++;
}
Well, I see only the last position, also if every thing seems
to go in the right way.
So, here are 2 questions:
There is a way to know if draw() has finish?
How long is "(somewhat later) FLTK will call draw()." ?
thanks, rogx
