Basically how do i declare a blob component such as a cylinder...?
It will not seem to accept the strength as a valid cylinder entry...?
I want to declare a component and use i.e. MyCylinder to rotate ti
around the central components w/ out rewriting the entire component...?

You could use macros
#macro MyCylynder(...) -y,+y,RB-.02 #end
#local S1=-50;#local S2=-100;
blob {
threshold .0001
cylinder{0,y*.06,RB,20}
cylinder{MyCylynder,S1 translate -x*.06}
cylinder{MyCylynder,S1 translate -x*.06 rotate +y*120}
cylinder{MyCylynder,S1 translate -x*.06 rotate -y*120}
cylinder{MyCylynder,S2 translate <0,RB,-(RB-.01)> rotate +y*030}
cylinder{MyCylynder,S2 translate <0,RB,-(RB-.01)> rotate +y*090}
cylinder{MyCylynder,S2 translate <0,RB,-(RB-.01)> rotate +y*150}
cylinder{MyCylynder,S2 translate <0,RB,-(RB-.01)> rotate +y*210}
cylinder{MyCylynder,S2 translate <0,RB,-(RB-.01)> rotate -y*030}
cylinder{MyCylynder,S2 translate <0,RB,-(RB-.01)> rotate -y*090}
sphere {0,RB,-100 scale <1,.65,1> translate -y*(RB*.35)}
}

Thank you i will try ( try is the operative ) this my macro skill is none at this
point.
But still worth a try...
It still is not a declaration where i can change all the declared components at
once. Or can i... Like i said i have no understanding of the macro.. Well almost
none...

There is now a tutorial available on using and making POV-Ray macros that may
help you understand them better -

Here is something using the same technique as mr.art's reply, but more self
explanatory.
It may do what you are looking for.
#macro Cy(PitchRad) <PitchRad,0,0> <PitchRad,1,0> Rad, Strength #end
#local Rad =1;
#local Strength =2;
#local Ang=0;
blob {
#while (Ang<360)
cylinder { Cy(4) rotate y*Ang }
#local Ang=Ang+20;
#end
pigment {Red}
}

I'm having the same problem as Moon47.
Do I take it from the various answers given that it is not possible to
declare a whole blob component?

What do you mean by "whole blob component"?
Blobs can be as complicated as you can devise them. You only have to see H.E.Day's
images
to see the power of blobs. Run the code I gave in my answer to Moon74 to see just one
blob.
In one blob you can keep on adding spheres and cylinders with positive and negative
strengths to add or subtract from the final shape. These spheres and cylinders can
also
be distorted by uneven scaling. The individual components in a blob can be given
different
textures and this can all add up to a fiendishly complicated object.
On top of this you can use csg to carve out or to add bits.
Alright, I've convinced myself, I must start to use blobs :-)

While I appreciate the praise ( who doesn't ? ) part of the credit should
also go to those writing the tutorials. Without their efforts I would have
nothing to link to.

One limit: A single blob cannot have more than one million components.

I mean that you cannot declare a blob component in the way that you can
declare a sphere or box. Instead you have to declare the individual vectors
and so on that make up a component.

I'll just have to try and keep them simple then :-)

OK Tom, we're just differing on semantics. Because a blob is not a regular geomtric
solid
the information necessary to define a blob increases with the complexity of the shape.
Even with a box you have to define the vectors that define it.

Any primitive can be #declared regardless of its complexity, but the
_components_ of a blob cannot.
There is a practical significance. E.g. blob components can't be stored
in arrays.

You're right now would be a good time to say that without this tutorial i
would not have finished my " Two Cents..." Post... A very awesome tutorial i
will make sure to than the author at first chance...
Thanks again... =)
