 Posted: Mon Mar 10, 2008 1:08 pm    Post subject: Hi all, Sorry quarmall for the delay in my response (I'm in the desert in the south of Morocco and internet isn't available in my village ) "condition CND" mean a mathematical equation that you can use to select a volume from your mathematical object (You can use it for example to calculate an intersection between a sphere and a cylinder) "ND" mean "N Dimension": This is to show and manipulate the mathematical objects with dimension up to 6. Hope this can help._________________Cheers, Abderrahman

For example, if I wanted to graph the region bounded by the paraboloids z=x^2+y^2 and z = 2-x^2-y^2. I have toyed with this, but am not quite sure I am doing it correctly. Thank you for sharing this beautiful wonderful program!

Hi all,
Welcome WSUCoug in the forum.

You're looking for the intersection of the volumes delimited by theses two isosurfaces? In this case, you have to use the function "MAX" like this:
max ( z-(x^2+y^2) , z -( 2-x^2-y^2) ) and the result is:

 Code: Name: IntersectCones F(): max ( z-(x^2+y^2) , z -( 2-x^2-y^2) ) [x]: -2 , 2 [y]: -2 , 2 [z]: -2 , 2 ;

If this doesn't respond to your question, let me know.

If I have to choose between the three, I'd prefer : Creative Nail Design... _________________Cheers, Abderrahman
