Isosurfaces - Help Scilab

Hello guys. All right? First of all, I apologize for my poor English. I'm new here and I've never used Scilab either. However I came across a problem and I believe that SciLab can be very useful. So for a total beginner, I ask for your help. If I can solve my problem, I will endeavor to study SciLab in more depth. The point is this. I need to trace some isosurfaces. For example (only a random example) x ^ 2 + y ^ 2 + z ^ 2 = r, where r = 1, r = 2 and r = 3. Or another random example (y-z) ² + (z-x) ² + (x-y) ² = 3R², where R = 1, R = 2 and R = 3. Neither of the two examples refers to my function, but I believe that with these examples I can trace my surfaces. In my case I should include intervals for x, y, and z. For example x (0 to 1), y (200 to 300) and z (80 to 100). Thanks in advance for the willingness to help.

If you are a total beginner in Scilab, I urge you to first go through some basic scilab spoken tutorials here. Also, I encourage you to first learn and try out a few things in order to solve the problem at hand, may be break it down in to simpler problems and then address it. As far as the mentioned problem is concerned, it has a good level of difficulty involved that may use polynomials, optimization and plotting featurs of scilab. So it will help if you learn scilab first.

Anyways, take a look at surf and contour functions in scilab and see if they help to solve the particular problem at hand.
