Hi All,
I am looking for a way to model the surface of an ellipsoid with
Mathematica 5.2.
To define the surface, i got an equation given below :
E[r_,d_] = Sqrt[r^2/9 + d^2/9];
Mathematica version of the above equation :
\!\(\*
RowBox[{
RowBox[{\(E[r_, d_]\), "=",
SqrtBox[
StyleBox[\(r\^2\/3\^2 + d\^2\/3\^2\),
FontSlant->"Italic"]]}], ";"}]\)
for example : the values of ' d ' ranges from -2 to 2 and ' r ' ranges
from -3 to 3.
Can somebody please tell me how to make a 3D ellipsoidal surface with
this information?
the aim is to place this ellipsoidal volume on one co-ordinate point
of a 2D image and check if there is any intercept with x or y axis
within this volume.
i really don't know, just with this information, if it is possible to
acheive the given task.
I sincerely appreciate your generous solutions or suggestions.
Mayneord.
