I am using MAPLE 2016.1.

I have created an animation of points on a polarplot (2D), but would like it to be projected into 3D, with time t being the 3rd axis.  Here is my code for the polarplot animation:

with(plots);
Repltlist := proc (t) options operator, arrow; [[sin(t), 0], [cos(t), (1/3)*Pi], [cos(2*t), (2/3)*Pi]] end proc;
Impltlist := proc (t) options operator, arrow; [[-sin(3*t), 0], [-2*cos(t), (1/3)*Pi], [-cos(4*t), (2/3)*Pi]] end proc;
titleName := "Polar representation of time-dependence of degrees of freedom in configuration space"; captionName := "Re - red, Im - blue";
P := animate(polarplot, [Repltlist(t), color = "Red"], t = -Pi .. Pi, symbol = solidcircle, style = point, color = red, symbolsize = 12, frames = 100, gridlines = true);
Q := animate(polarplot, [Impltlist(t), color = "Blue"], t = -Pi .. Pi, symbol = solidcircle, style = point, color = blue, symbolsize = 12, frames = 100, gridlines = true);
R := display([P, Q], title = titleName, caption = captionName); R;

I have been trying use the plots[transform] to 'lift' this polarplot into 3D: 

with(plottools); with(plots);

plrPt(2); f := proc (tt) options operator, arrow; plottools:-transform(proc (r, theta) options operator, arrow; [r, theta, tt] end proc) end proc; display((f(2))(plrPt(2)));

but the last command gives no output.

Can anyone help?

PS:  I am now attemptiing to do the lift to 3D by using a cylinderplot but would like know why the transform function is not able able to lift the polarplot into 3D.

I am running MAPLE 2016.1

I am able to set the color option to a function in fieldplot, e.g.

plots[fieldplot]([y, -sin(x)-(1/10)*y], x = -10 .. 10, y = -10 .. 10, arrows = SLIM, color = sin(x)*sin(y))

works as expected.  

However, for plots[fieldplot3d] I cannot set color = f(x,y,z) . E.g.

plots[fieldplot3d]([2*x, 2*y, 2*z], x = -1 .. 1, y = -1 .. 1, z = -1 .. 1, grid = [5, 5, 5], arrows = SLIM, color = sin(x)*sin(y)*sin(z));

Error, (in plot/color) invalid color specification: sin(x)*sin(y)*sin(z)

Please can anyone help?

I have worksheet that generates very large matrices and it seems to save all results, so it requires large amount of RAM to load and storage to save it.  

There used to be a pop-up prompt not to save the results of the worksheet - to save space, but that no longer occurs.  Can someone help me to switch on that prompt not to save results or otherwise prevent saving results, when I open the spreadsheet.  It maybe that I agreed not to be prompted again, but now I am regretting it!!

How long will MAPLE 16 and future versions of MAPLE will support running on Windows 7?

(I hope to defer transferring to Windows 10 until MS stop supporting for Windows 7.)

I wish to display the following screen output from a procedure A(), in a textbox of mathcontainer or any other suitable component.

This output to screen listing is generated by print statements in the procedure A().

I have placed the procedure call A() in a textbox and then am using a button component to execute it with the objective of displaying the above output in another component display box; either a textbox or a MathContainer box...  I can see that A() executes, but do not know how to get the result to display in a component box.

Can anyone offer any help?
