Scratchings from whiteboard:
Main application loop:
for( ;; )
{
CameraGroup::sync();
preCull Traversal;
CameraGroup::frame();
}
CameraGroup::frame()
{
Barrier.release();
}
CameraGroup::sync()
{
Barrier.wait();
}
Two possible Camera implementations:
A) ======
Camera::thread()
{
for( ;; )
{
Barrier.wait();
cull();
SVR(); // Sync Vertical Retrace
draw();
Barrier.release();
swapbuffers();
}
}
B) ==== Threaded Cull
Camera::thread()
{
for( ;; )
{
Barrier.wait();
CullDrawBarrier.release();
CullDrawBarrier.wait();
swap scene view buffers;
Barrier.release();
}
}
Cull::thread()
{
for( ;; )
{
CullDrawBarrier.wait();
cull();
CullDrawBarrier.release();
}
}
Draw::thread()
{
for( ;; )
{
CullDrawBarrier.wait();
draw();
CullDrawBarrier.release();
}
}
