Every animation, or dynamic presentation, needs a FIXED BACKGROUND. In this
case a fixed PlotRange. Also, ListAnimate appears to require more than two
items in the list.

a = Graphics3D[Line[{{0, 0, 0}, {0, 1, 0}}],
   PlotRange -> {{0, 2}, {0, 2}, {0, 1}},
   BoxRatios -> {1, 1, .25}]; 

b = Graphics3D[Line[{{1, 0, 0}, {1, 1, 0}}],
   PlotRange -> {{0, 2}, {0, 2}, {0, 1}},
   BoxRatios -> {1, 1, .25}]; 

ListAnimate[{a, b, a, b}, 2]

Hi,

Can one use ListAnimate with Graphics3D primitives?

I have two lines created by

a = Graphics3D[Line[{{0, 0, 0}, {0, 1, 0}}]];
b = Graphics3D[Line[{{1, 0, 0}, {1, 1, 0}}]];

and the following

ListAnimate[{a,b}]

doesn't show an animated sequence of two line alternating.

Any suggestion is appreciated,

Michuco
