I would like to plot this :

yz(x+y+2z)^3-8=0 such as x^2+x(y+2z)-1<0 and y^2+y(x+2z)-3<0

The difficulty is that bounds depend on other variables. I was trying to use Maple implicitplot3d function, but I don't see a way.

Is it possible to use Maple for such plot ? If so, how ?


Thank you for your answer

Hi all,

I'm trying to plot the regions of a cube that are defined by an inequality. At the moment I am able to plot only the surface defined by the corresponding equality. 

That's the code: 


implicitplot3d(x^2*y = z, z = 0 .. 1, y = 0 .. 1, x = 0 .. 1);

Now I would like to plot the two regions defined by the corresponding inequality. 

Have you got any idea on how to do this?



Several years ago, I used to plot, in Maple 7 I think, 3D scalar functions by using procedures to create a 3D mesh and populate the data points before I could use plot3d.

I wonder if there is a more convenient (least coding) way to do it today? Consider for example f(x,y,z) = x^2 + y^2+z^2

A way to visualize a number of concentric isosurfaces of f is to loop with (is there a tag to write this in code block?): 


for i to 10 do iso[i] := implicitplot3d( f = i, x = -10 .. 10, y = -10 .. 10, z = -10 .. 10) end do

display(seq(iso[j], j = 1 .. 10))


Of course, visualizing the output is another issue.  I wish for an app to explore 3D data like Paraview. It does not have to be as sophisticated, but to display standard elements like isosurfaces and arbitrary cutting plane views would suffice.

If you know a package/app/procedure in Maple of this nature, please share it here. Thank you


How do I plot the imaginary or real part of a complex valued function



I tried:



but which does not work

Hi all,

I have been trying for some time create an animation of a 3d plot I created rotating about the z-axis in Maple 15. I tried using the usual


but not only does that produce an error when I try to do the same thing with an implicitplot3d function, it also doesn't work when I try to animate multiple plots in the same graph, whether implicit functions or regular plot3d ones. I am creating a model...

An implicitplot3d of an f(x,y,z)=0 results in an ISOSURFACE structure containing the samples of a function taken over a regular grid in 3-D space and is rendered as a 3-D surface approximating the zero surface of the function.
When I select the points with values of f(x,y,z) "close" to zero, I only get a few points on the surface:

q := plots:-implicitplot3d( x^2+y^3+z^4=1 ,x=-1..1,y=-1..1,z=-1..1,
style=wireframe, color=black ):
pdata := plottools:-getdata(q); # doesn't work...

how to graph this two paraboloids into one graph in Maple? z=x^2+y^2 and z=2-x^2-y^2  I try to use Display, Display3d commend, and it doesn't work.







and if I want to combine the two graph into one, what should I do next?

I'm having an issue with the implicitplot3d command in Maple 16.  The sequence of commands I've listed below works just fine in Maple 15, but in Maple 16 I'm getting a problem.  Sometimes no graph will display;  other times, Maple may initially graph the surface correctly, but as soon as I rotate the graph, the surface disappears.  Furthermore, the following strange things happen:


1) Re-executing the command after rotating does not redraw the image ...
