patch [#28218] During-render callback functionality
from Jesse Kaukonen (gekko)
--- text from the patch.
Recently Campbell Barton added callback functionality for Python's usage, but
this only includes pre- and post-render callbacks. There are no callbacks for
the duration of the render. This patch adds the few lines required for
executing a callback while Blender Render is working. The callback resides in
the rendering pipeline stats function, so whenever statistics are printed, the
callback is executed. This functionality is required if one wants to:
1) Observe what is happening while Blender is rendering via the command line
2) Add custom statistics that Blender prints while the renderer works
3) The user wants to continue executing his Python script without the code
halting at bpy.ops.render.render()
Personally I'm currently using this for printing out more detailed progress
reports at Renderfarm.fi (such as CPU time, time spent rendering, total
progress in regards to the entire rendering process). Tested on Windows, Linux
and OS X.
Example on how to use the callback:
def statscall(context): print("Thanks for calling!")
bpy.app.handlers.render_stats.append(statscall)
bpy.ops.render.render(animation=False, write_still=True)
