You might like 'SuperShape' based formulas. They are a bit more
intense math wise, but have a super wide variation of output.
Alex/Toneburst has one I recall on his site.

Hello List!
I would like to add more shapes to this function in GLSL. I found in
one composition from Toneburst that he used ' return (SphereTorus ==
0.0) ? qSphere : qTorus; ' to choose from diferent equations but now
I would like to add a third and forth equation but my logical
thoughts aren't working. so I would just add ':' as you see in this
example. So my question is how can I add more than two equations?
vec3 functionShape(in float theta,in float phi)
{
vec3 qSphere;
qSphere.x = sin(phi) * cos(theta);
qSphere.y = cos(phi);
qSphere.z = sin(phi) * sin(theta);
vec3 qTorus;
qTorus.x = radio * cos(theta);
qTorus.y = largo * cos(phi);
qTorus.z = radio * sin(theta);
vec3 qSquare;
qSquare.x = radio * cos(theta);
qSquare.y = largo * cos(phi);
qSquare.z = radio * r * sin(theta);
return (SphereTorus == 0.0) ? qSphere : qTorus : qSquare;
}
Thank you!!!
