Actually, I guess it is a qtpovray question:

In POV-Ray for Windows, you can select a region of the preview with the
mouse and it will give you the option to re-render only that portion of
the scene (by quietly passing `+sc`/`+sr`/`+ec`/`+er` information to the
render engine).

You can also shift-select the region and it will give you the option to
add/replace the corresponding command-line switches to/in the
command-line input field, so that later renders will also render that
particular portion.


I think Bald Eagle's question was whether qtpovray also provides a
mechanism to set those switches using only the mouse.
