They are just using tree as an exotic example of an arrowhead. The Head of
tree is Graphics. You can create any other Graphics object. For example:
circle = ParametricPlot[{Cos[u], Sin[u]}, {u, 0, 2 \[Pi]},
Axes -> None];
Graphics3D[{Arrowheads[{{.1, 1, circle}}, Appearance -> "Projected"],
Arrow[{{0, 0, 0}, {0, -0, 0.001}}], Green,
Cuboid[{-10, -10, -3}, {10, 10, -2.8}]},
SphericalRegion -> True, RotationAction -> "Clip"]

Hi Forum
I am trying to use the following command:
Graphics3D[{Arrowheads[{{.1, 1, tree}}, Appearance -> "Projected"],
Arrow[{{0, 0, 0}, {0, -0, 0.001}}], Green,
Cuboid[{-10, -10, -3}, {10, 10, -2.8}]}]
This is taken straight out of the arrowheads help section in mathematica
help, and tree here is a graphics object that is inputted before this
graphics command.
So, this command works fine. But the problem occurs if I try to use a
different graphics object, other than the tree they provide in the example.
I can't get any other graphics object to work here! Will it only work with a
very particular kind of object?
Hope someone can help.
