First parameter: t, range (0,pi)
Second parameter p, range (0,2*pi)
Expressions
x=(1+0.1*(sin(t))^4*cos(4*p))*sin(t)*cos(p)
y=(1+0.1*(sin(t))^4*cos(4*p))*sin(t)*sin(p)
z=(1+0.1*(sin(t))^4*cos(4*p))*cos(t)
I get a domain in the graphics window despite the warning message
Maximum relative error of parametric surface representation is 7.557101504372923E-4.
However, I wan unable to convert the surface into a solid because I get the warning
Output object is empty.
I tried to reduce the range of the parameters and divide the surface into smaller parts, but it didn't help.
If I increase the paramter 0.1 in the expressions, the generated surface looks very unsmooth and teared. This is not normal since my function is indeed very smooth.
