Hi Bob,
The answer is in the source ;-)
Viewer::run() is bascially equivilant to:
while(viewer.done())
{
viewer.frame();
}
And frame itself is bascially just a call to advance(),
eventTraversal(), updateTraversal() and renderTraversals() so can be
rewritten long hand:
while(viewer.done())
{
viewer.advance();
viewer.eventTraversal();
viewer.updateTraversal();
viewer.renderingTraversal();
}
There is no delays adding it to control frame rate, this left entirely
up to the OpenGL fifo, which in the end is blocked by vysnc, the loop
doesn't switch off until done is called. If you write the frame loop
yourself as above they you can insert a block/sleep anyhow you want.
Don't forget Viewer::run() and Viewer::frame() are just convenience
methods, nothing more.
Robert.
In you own app what you need to do is write you own run method and add
in an optional sleep method into the above loop:
