Hello,
how can I distribute some points randomly on sphere, but that they would be +/- in
same range from 
each oter (uniformly) ?

    #local R1=seed(3433452);
    #local I=0; #while (I<500)
      #local B = vrotate(<0,30,0>, <rand(R1)*360,0,rand(R1)*360>);
    #local I=I+1; #end

this method is wrong, because poins are close togeather at top and bottom of sphere
and there are few 
in middle


-- 
#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M
