If you want to render a lot of spheres at every frame,It is better to reduce the precision of the fractal properly.Only if you call Spheredetail () and give a new precision will the settings really change, so don't eachSpheres are called once--unless you want their accuracy to be different--to lower the precision of a small object, far from the lens,This can improve efficiency.If yo

When the lock is released, the prenode of the previous node is = avaiable, automatically notifies the next node to obtain the lock * When a node times out or is interrupted, its precursor node is not empty. When the subsequent node sees that its precursor node is not empty and is not available, it will know that the nod

Of course, encountering a cancelled thread requires that it be removed from the FIFO queue.
