Hi,
Buffers for points are round. There are also round corners for
line/polygon buffers, depending on the linecap styles and line join
styles. QGIS and simple features can only display straight lines. The
number of the segements to approximate means the higher the number, the
more vertices you will have for a circle approximation.
See also http://postgis.net/docs/manual-2.1/ST_Buffer.html as an
explanation for buffer styles and segments.

Hi all
Is there anyone could tell me what is "segments to approximate" in the
buffer tool ?
I know that if I increase this value, there's more nodes on my buffer
but I don't know what is it exactly and how we can choose this value.
Thanks
Regards
Ludovic
