Data in 3D plots can now be dynamically clipped to the axes view limits
2+
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3+
4+
All 3D plotting functions now support the *axlim_clip* keyword argument, which
5+
will clip the data to the axes view limits, hiding all data outside those
6+
bounds. This clipping will be dynamically applied in real time while panning
7+
and zooming.
8+
9+
Please note that if one vertex of a line segment or 3D patch is clipped, then
10+
the entire segment or patch will be hidden. Not being able to show partial
11+
lines or patches such that they are "smoothly" cut off at the boundaries of the
12+
view box is a limitation of the current renderer.
