Dear Maple users

I know how to plot surfaces in 3D. However now I have a special task: I want to plot a piece of a solid region in 3D, more precisely a transverse or logitudinal wave. I wonder if there is an easy way to do this in Maple? Any hint will be appreciated!





Notice it doesn't completely go down to the x-axis. 

It can be partially fixed with this


but due to bugs in earlier versions of maple I can only achieve this

Use the Gram-Schmidt process to transform the basis

{Vector(3, {(1) = 0, (2) = 1, (3) = 1}),

Vector(3, {(1) = 1, (2) = 1, (3) = 1}),

Vector(3, {(1) = 1, (2) = 2, (3) = 3})}

for the Euclidean space R3 into an orthonormal basis for R3

Show 3D result.

I see there are functions for 3-dimensional planes and spheres but what about arbitrary curves?

For instance I have the following 3D curves: z = y*log(x) and z = y + x*log(x)

  1. How can I compute the intersection of these curves?


I am a student and I am new to the maple software. I need some help with generating a 3d curve fit for data from excel. I have attached sample excel sheet.


I am trying to get a relation of X(1st column) in terms of Y(2nd column) and Z(3rd column). Also is there a way where I can define the relation and maple can find the coefficients(a,b,c,d,e) of the expressions? such as: X=a(Y^3...

I was using maple the other day, and suddenly i found out my 3D graph turned into black, but when i save the file as pdf, it could show the graph. And also it doesnt affect the maple displays 2D graph. So i wonder how did this happened and how i fix it.

My answer in this topic does not load for some reason, so I had to create this post.

Variant of solution:

I want to graph the portion of the plane 2x + 3y + z = 6 that are located in the first octant of a xyz coordinate system. The following implicitplot3d should in principle do it:


I have a table T where the indicies are pairs (a,b) of integers with 0<a,b<50. Is it possible to make a 3D plot with a point (a,b,T(a,b)) for each (a,b) in the domain of T?

I tried to use multiple light sources with transparency for 3D plots and could not get it to work.  There are indications in the plot,structure help that this is supposed to be possible.  I have attached a worksheet that demonstrates some of the problems with the "light" and "LIGHT" options for 3D plotting.  Much of the output has been removed since the graphics take so much space.  The same plots are generated in both Windows and Linux.

Does anyone...

I've a 3d surface built by the point's set;

It looks like this:


The question is:

1. how to build a surface based on this data?

2. how to define whether the arbitrary point (x,y,z) is inside this surface or not?

Maple 16 introduced dramatic changes to the postscript export facility of 3d plots. This is great news, but some bugs remain. Let me report here about my experience. (Note: Maple 15's 3d ps export was something like an encapsulated bmp, while Maple 16 is a genuine level3 postscript export tool)

The initial release in Maple 16.00 was buggy. In my experience, the export would hang most of the time. An improved release came with Maple 16.01. I have not experienced any...

Is there some way to do this?  I am hoping to export the plots to x3d files with the ultimate goal of sending the files to a company that can print them on a 3d printer.  (for example, Shapeways  ) 

Hello! I am trying to graph the following: 

dx/dt = -10*x + 10*y 
dy/dt = r*x - y - x*z 
dz/dt = -(8/3)*z + x*y 

where x, y, and z are all functions of time (t). Solve the equations subject to the constraint that r = 25 and the initial conditions that at t = 0, x = -1, y = -1, and z = 1. 

This is my code:
DE*plot3d({d*x(t)/dt = -10*x(t...

So I want to display a plot containing a spiral and a polygon graph approximating the shape. I use a seq to make the points in pointplot3d and then connect them with the connect option. It looks like this:

graph := spacecurve(y(t), t = 0 .. 6, thickness = 3, axes = box, color = blue):
poly6 := pointplot3d({seq([cos(t), sin(t), t], t = 0 .. 6, 1)}, connect, axes = box, 
color = red, thickness = 3, caption = {n = 6}):
