Multiple polar plots into a 3d plot

[Sunnyliu]

I found the LabVIEW help is confused me. 

Please see the attach file.  Theta and Phi are wrong place in the Spherical Coordinate.

To compare with http://en.wikipedia.org/wiki/Spherical_coordinate_system

And what makes you think Wikipedia is correct?

In my math experience, Theta has always been the angle in the XY plane just like it is when you deal with 2-D coordinates.  While phi is the angle out of the XY plane.  Exactly what LabVIEW help shows.

After to call 3D Coordinate Conversion.vi. LabVIEW help is correct. But the usage theta and phi is opposited with Wikipedia.

It let me confuse that!

Have a Nice Day!

I'm glad you have it figured out.

By the way, I trust LabVIEW's help.  It matches my experience.  I don't trust Wikipedia.  Any goofball can create those articles.

Hi, new LabView user.

We are working on measuring magnetic flux device and want to use this visualization as a part of LabView software. We have 4 dimensions in our data (height, radius, and a polar angle for the space description and a measuments as a value). We want to represent the 4th dimension as intensity/color. As the device hasn't been already made, we use simulated data in order to get to know with a VI.

I wonder if it's possible to bring x, y, z vectors from the polar coordinates we obtain and than import value seperate in Wmatrix. Any explanation of possibilities would be helpful.

Tnx, Bostjan

if I follow you correctly yes.

The data presented to all of the inputs XYZW must be the same number of dimensions and also sized the same.

Think of each surface as a bed sheet where each intersection of fibers has a color defined in the W vector. For each of those W values it needs to know what the XYZ values for each of those.

I suggest you look at this thread where I collected a bunch of examples with links to the original threads. All of those threads have code examples included.

Start with the 3D Car and after you get comfortable with how to manipulate your data sets to get what you want, then move on to the other examples.

hello, ben,

            Could you give me some help to draw the isocandela graph,thanks.
