(I think I goofed, so this is a repost)

Just picked pov up again after about 2 years of not using it at all
Started rehashing old stuff that I did.

Any comments or suggestions?

Only one: how did you do that?! I've *just* started trying to do exactly the
same symbol and I've got no idea where to start! Blobs? Sweeps? Heightfields?

Give me a clue?!

Cheers,

Steve

I used a sphere_sweep, getting the sphere placing took a bit of math,
and some trial and error.

This is probably the bit that you're after

// yy_n is the number (visible) sweep components
// (higher = better definition,  but slower)

#declare yy_n = 15; 
#declare yy_i = -1;

sphere_sweep {
    b_spline
    yy_n + 3,

    #while( yy_i <= yy_n + 1 )
    
        #declare yy_a = radians( (yy_i / yy_n) * 180 );
        #declare yy_x = cos( yy_a ) / ( cos( yy_a ) - 3 ) * 2;
        #declare yy_z = sin( yy_a ) / ( cos( yy_a ) - 3 ) * 2;
        #declare yy_r = ( cos( yy_a ) - 1 ) / ( cos( yy_a ) - 3 );
        
        <yy_x, 0, yy_z>, yy_r           // place node
    
        #declare yy_i = yy_i + 1;
    #end
    
    tolerance 0.1
    scale <1, 0.5, 1>
}


I've also attached a couple of images with transparency and photons.
I could have picked better colors, but I like the light patterns cast
by the photons.

Beautiful images, especially the glass ones,

That'll have to wait, I have not played around with radiosity yet.

The source is in p.t.s-f, why don't you do the honors.
