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! |

Even creating a sphere is somewhat difficult. There have been questions in this forum on creating a sphere. I list four of these below. For a "revolution solid", it would be more complicated.

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! |

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!
