Perfect! Thanks Colin. That was exactly what I was after and has got
things back to a usable speed.

You can use memset to set ( reset ) a whole rows values to black -
remember that nuke gives you the pointer to x = 0 but engine may have
only validated between x and r so you need to accommodate for those (
and all of your channels ).
row_ptr = row->writable(z);
memset(row_ptr + x, 0, (r - x) * sizeof(float));
As for draw_engine, DrawIop inherits from Iop so request could be used
to precompute your values.
cheers.

Apologies for dragging this subject back up but there's still a few
things I need to get clear on.
Ok, so I have a my vector full of points defining a curve that I'm
pre-processing using a locked thread. I'm able to sort the vector to
an upper/lower_bound as mentioned by Colin so I don't have to iterate
through every point which speeds things up a bit. So essentially,
