Ah!
Right (apologies to non-POV users here!)
The light beam is a media cylinder and a cylindrical light source.
Code:
cylinder { < 0, 0, -300>, <0, 0, 20>, 3
pigment { rgbt 1 }
hollow
interior { media { scattering { 1, 0.001 extinction 0.01 } samples 30,100 } }
}
light_source { <0, 0, 20> color rgb <150, 150, 350>
cylinder
radius 2
falloff 4
tightness 5
point_at <0, 0, -300>
}
[Hrm, the editor seems to remove indents!]
To be honest I haven't got a complete "handle" on all the parameters used so I tend to use "educated trial and error" for what I want and as usual, Serendipity often has the final word! As you can see the light is pretty bright ! The "sun" I'm using is only rgb 2*<1, 0.97, 0.94>.
I'm all up for any advice on these matters, this is only my second attempt using media.
The trees? Home made. With the exception of the "leaves" on one tree - which uses a highly modifed leaf texture tile from Maptool/FM8 - everything in this entire design is essentially home made. Whilst I'm sure you're aware there are one or more tree generator POV sources available for free on the web, they're all "too good" i.e represent the workings of real POV experts seeking perfection. Whilst I admire their works, I needed some simple, rather quicker to render, trees. So a fairly simple four layer random branching algorithm and some simple leaves...

[The trees on roofs and paths are in pots!]
The "tree fern" thing is just some tori for the trunk and a sliced up sphere/cone difference for the "leaf", the "normal tree" has each branch ending with a sphere image_mapped with that leaf texture I mentioned - modified so that the darker shades were transparent - and the "cactus" is just 6 flattened spheres rotated to make a segment with a load of spines that are frankly a little OTT for detail here. I tend to try and create stuff I can add to my "library" of bits for other projects later on.
Any help? ( I'm happy to give people source for this stuff - just give me time to tidy up the messy code and add the appropriate CC license! )
