Description (last modified by yzh)

The methods sage.plot.plot3d.shapes2.polygon3d and sage.plot.plot3d.shapes2.polygons3d have the keyword argument "alpha" (as well as the equivalent, outdated "opacity" argument). However it is not passed to the plot function. For example, 

polygon3d([[1, 2, 3], [0,1,0], [1,0,1], [3,0,0]], color=(0,1,0), alpha=0.5)

or 

polygon3d([[1, 2, 3], [0,1,0], [1,0,1], [3,0,0]], color=(0,1,0), opacity=0.5)

is treated as opacity=1.

Related tickets: #21984

Update: The argument "alpha" is equivalent to "opacity" in all the 3d plot functions, such as point3d, line3d, sphere, icosahedron, tetrahedron, dodecahedron, polygon3d, polygons3d, bezier3d, parametric_plot3d, revolution_plot3d, `arrow3d', etc.

For consistency, use alpha instead of opacity, see #21984.
