Origin Version (Select Help-->About Origin): 7.5
Operating System: suse9.1 (using CrossOver Office)
Hi everybody,
I was wondering if there was any way to generate a revolution solid in Origin. I have a program that generates the values of a rotationally invariant function as a function of radial distance. I'd like to get a nice 3D representation of the data, but I'm not sure how to do it! Currently, I just have two columns of data:
r | f(r) (it's independant of the angle)
___________
0.0 | f(0.0)
0.1 | f(0.1)
0.2 | f(0.2)
... | ...
Is there any way to get a solid of revolution from this?
Thanks! |

Hi quickkk,
Origin's 3D graphics do not support the drawing of solid objects (i.e. the plotting of objects which have multiple Z values per XY pair). That said, it may be possible to generate a 3D solid by glueing together two halves. For more information, consult the Origin Help file topic Displaying Multiple 3D Surfaces or a 3D Surface and Multiple 3D Scatter Data Plots. The mathematics of what you are attempting are beyond me, but someone else may have some suggestions. Good luck!

Hi Mike,
Thanks for the reply, I really appreciate it. The function that I'm trying to plot in 3d doesn't have multiple z values for each (x,y) point. For example, say my function is f(r)=r^2. In 1D (r=x), I just get a parabola. However, I can also get a 3D version by "rotating" the f(x)=x^2 all around the z axis. I'd get something that looks like a parabolic mirror. My problem is that all of my data is just as a function of radial distance r. It's too complicated to try and recreate a x,y and z column from the r,f(r) data so I guess that I'll just leave in 1D.
Once again, thanks for the help! |
