hello every one , I have a 3d cylinderical shape with temperature distributed in this cylinder in a given function. the question is , can this be ploted by matlab??

thank you so much.

[Jacob Ward]

Simple answer is yes it can be plotted in MATLAB. Could you provide some more details? How are the cylindrical shape and temperature distribution defined?

[John D'Errico]

Well, yes, if something CAN be plotted, in a meaningful way, you can always plot it in MATLAB.

The thing to remember is that a plot is a TWO dimensional thing. Think about the face of your screen. TWO dimensions.

If your goal is to plot something like a temperature that varies through the volume of a cylindrical volume, then think hard. What do you expect to see? How will you visualize something like that?

Even when you have a 3-d scatter plot, you can usually only make sense of it by doing things like rotating it around. That way you can see what lies in front of what. In the case of a temperature that varies all over a 3-d volume - this is a 4-dimensional thing that you are trying to visualize using a 2-d graphic tool. You can try to use color to denote temperature, but even there remember that this is essentially a solid object. Transparency is only useful to a very limited extent.

thank you jacob and john, the problem I am working on is that I have a laser source focused on the top of the cylinder, I have calculated the temperature using (monte carlo simulation),a theory that describes how the light is distributed in the cylinder. I know how to plot 2-d cases using meshgrid , but I have never dealt with 3-d cases

Answer 2

[Precise Simulation]

Another option if you for example want to plot and visualize 3D iso-surface, slice, arrow, or further postprocess your data (see link with examples of cylinders with scalar data similar to Temperature field).
