beginner question.... creating 3D plots from a 2D array

I am sure there is a simple solution to my question.... give the attached file, I am trying to compute the radiant energy from a fire to a target (using the point source method) and wish to turn the 2D plot into a 3D plot as a function of distance and angle from the fire.  Meaning, if the fire is at coordinates 0,0, I am trying to figure out the commands for placing the target from 1 m to a given distance (in this case 121m) from the fire in any direction along the x,y coordinates and then plot in 3D.... I am sure its easy, but this rookie can't figure it out... Any assistance is appreciated.

Here is how to create the surface of rotation, if it is this you are looking for.

For a fully closed surface you'd had to exchange the pi/3 for a 0.

Unfortunately Primes 3D plotting capabilities are quite mediocre, even compared to real Mathcad. No colormap, no transparency effects, no lighting, no control over perspective, no contour fill, bad autoscale, ... and a lot of other drawbacks. Its quite impossible to make the plot at least nearly good looking.

Not sure what exactly you'd like to achieve.

Guess the angle you are talking about is NOT theta because theta depends on L.

Do you simply want to rotate the curve you plotted around the q'' axis?
