Hello,

I have to make shorter this membrane I don't know how can I do it. I also
make an angle like a bridge I trayed with sine and cosine but, logically,
it's doesn't work like I need. The code is:

#include "colors.inc"
#include "textures.inc"
  background { White
  }
  camera {location <170, -11, -110>look_at  <180, -15, -16>}
  light_source { <170, -30, -100> color White}

#declare lipid =  union {
                        blob{  threshold 0.1
                                sphere {<0, 0, 0>, 2 ,1 texture {pigment {
color Red }finish { ambient 0.2 diffuse 0.8 phong 1 }} scale 0.8}
                                cylinder {<0.8,0,0>,<0.8,-5,0>, 0.5,1
texture {pigment { color White }finish { ambient 0.2 diffuse 0.8 phong 1 }}
scale 0.8 }
                                cylinder {<-0.8,0,0>,<-0.8,-5,0>, 0.5,1
texture {pigment { color White }finish { ambient 0.2 diffuse 0.8 phong 1 }}
scale 0.8 }
                        ////rotate <0, 0, 0> translate <0, 14, 1>
                        }

                        blob{  threshold 0.1
                                sphere {<0, 0, 0>, 2 ,1 texture {pigment {
color Red }finish { ambient 0.2 diffuse 0.8 phong 1 }} scale 0.8 }
                                cylinder {<0.8,0,0>,<0.8,-5,0>, 0.5,1

                        translate <90, 0, 0> scale 0 scale <0, -0.78, 0>
                  }

Oleguer, I don't understand what you are trying to achieve.

Maybe that is because I am not able to understand your
spanish(?) comments and because I know little about lipids
and membranes.

(Babelfish at http://www.infonegocio.com/oleguervm could
not help me much either ):

Please try to explain more. Do you have links to any images
that shows similar shapes to those that you are trying to
make ?


In order to make it easier for others in these news groups
to help, you should try to make your code more structured
and readable. I have done this with your code -> See below.


Remember that the sin() and cos() functions in POV-Ray
expects their arguments to be in radians, not degrees.

Hello,

Well, if you render my picture you will see a very large membrane. I want
make it shorter, for example: if it's 14cm I will make it 10cm. You don't
have to look my web site, only you should run the code that I have sent in

I'm not sure if I understand you, but below is my best try at
guessing what you want.

Note that I wasn't referring to any images on your website.
I was just thinking that maybe you had seen something similar
somewhere else on the internet that could give me a clue on what
you want.

By the way: Can anyone else tell me why I get this warning ?

   File: E:\Raytracinger\Lipid.pov  Line: 97
   Warning: No pigment type given.

Line 97 is at the end of the union {}
All the blob components has pigments, as far as I can see.

Should I go and Read The Fine Manual ?

I'm not sure if it says anything about what I believe it is. The blob object
lacks a pigment for itself, meaning that those given for the component parts
aren't the entire blob's texture or pigment.

Might seem redundant to add an unused pigment but I don't think it was ever
changed to find if every part had a pigment already and skip the warning.

Ok, I see.
