This question is based on the following worksheet I created specifically to show my question: Animation_Test.mw
Unfortunately, MaplePrimes gives me an error when I try to insert the contents here directly.
Basically my question is about the syntax of plots:-display.
I have a sphere
sphereDisplay := plottools:-sphere([0, 0, 0], 1, transparency = 0.9);
and something which is the result of calling plots:display on a sequence of two other other plots:-display.
arrowAndTrailDisplay := plots:-display(seq(plots:-display(computeArrowPlotFrame(m, t, red), computeTrailPlotFrame(m, t, windowSize, red)), t = times), insequence = true)
You can see in the attached worksheet what computeArrowPlotFrame and computeTrailPlotFrame are, but they are basically lists of plot structures. arrowAndTrailDisplay is thus an animation containing two different sequences of frames.
I wish to have Maple plot the sphere and the animation together. This works as expected (a static sphere and the animation of an arrow and a trail of the path of the tip of the arrow)
but the following does not work as expected (instead it plots each frame separately)
adding insequence=true to the latter makes it work. But my question is why do I have to add that? I can't understand, from syntax standpoint why the former plots arrowAndTrailDisplay as an animation but the latter does not.
