At the risk of sounding completely ignorant, where do the formulas for 
iso-surfaces come from.  I look at them and have no idea what they mean.
Does one need to be a math major or can we music business majors figure this
out?

Help

Thanks

  I think it would be a swell idea if one of the math majors around here
would write a tutorial on how to correctly enter equations in the syntax
needed to satisfy the requirements of the iso surface function. I too am
a bit mathematically challenged. I have resources for all kinds of different
surface definitions but don't know how to present them to the program.

  Understanding a high school level math book will certainly help.

Hello Craig. I never actually took algebra, and the geometry I took was very low
level stuff (I did graduate high school) , yet I've been able to get predicted
results when creating functions for the isosurface. It just takes time to learn
what the numbers mean. I have started a tutorial about using isosurface
functions. It is at the website address below.

The tutorial provides "base knowledge" information about creating functions. I
will announce future tutorials at the general discussion area of this newsgroup.

I am likewise confounded by much of it.  Algebra seems the most beneficial
math concerning the isosurfaces to me.  So at least that shouldn't be too
difficult to grasp.

Thanks everyone.  This at least gives me an idea.

I haven't even *finished* high school and I'm not having any problems predicting
what the results of a iso-surface will be.  Of course I'm no math whiz but I've
been doing Povray for about 3 years. My advice?  Test all the functions
(abs,sin,tan,max,etc.) and the try to combine them.(abs(x+sqr(y)+sin(z))
Good luck!
