Just wondering if anyone can help me with a little programming math i'm having trouble with.
What I am trying to create is a submit script (using python and .bat) for Nuke (vfx). The issue I am having is I can't figure out how to add the remainder of frames to the already calculated stack.
To be more clear...
In Nuke, i have to render 20 frames. I have 16 threads. Nuke only uses 1 thread. I want to write a script that takes the number of frames and divide it by the number of threads and write out a bat file using python. The issue come is when I have a remainder. I want to take the remainder and apply it back in the render stack.
example (first loop)
thread1 = 1 frame
thread2 = 1 frame
thread3 = 1 frame
thread4 = 1 frame
thread5 = 1 frame
thread6 = 1 frame
...
thread16 = 1 frame
Once it has done this...the remainder is 4. I want the remainder to be distributed among the threads. so...
example (second loops)
thread1 = 2 frame
thread2 = 2 frame
thread3 = 2 frame
thread4 = 2 frame
thread5 = 1 frame
thread6 = 1 frame
...
thread16 = 1 frame
the 4 gets added among the first few threads totalling 20 frames.
I will greatly appreciate any help, tips, comments that anyone has to offer. :)
Thanks
frames can be a list of any object, eg dict or "Frame" object. Here I have just used ints
>>> frames = range(20)
>>> threads = 16
>>> [frames[x::threads] for x in range(threads)]
[[0, 16], [1, 17], [2, 18], [3, 19], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15]]
I think you may be better off putting the frames in a Queue though, since some frames may render faster than others
