Hi
Here, on and off the western dangerous shores of France, we have a lot of
lighthouses. I keep on modeling some of them.
This one is the Creac'h (the Headland in Breton language) raised on the isle
of Ouessant at the entry of the Channel. It is one of the most powerful in
Europe. It can be seen from 150km.
Modeled in Moray... mostly CSG, some meshs, some isosurfaces (sea and land),
trace() used for the grass and I played with the compulsory IvyGenerator of
course :)
I unsucessfully tried to get rid of deformation of the tower due to
perspective :-(
Comments are welcome of course but I don't think I'll change many things.
Marc

That's brilliant, Marc. A bit too clean but it jut might have been painted.
What do you mean about getting rid of deformation of the tower due to
perspective?

Nice! I think POV is great for architecture.
How did you do the stone on the walls? Was it built "brick by brick"
algorithmically, or is it a solid something with an appropriate texture,
and if so what texture? I've been wondering for a while how to make
such a texture. :-)

Thanks :-)
It is a on land lighthouse and kept very clean and well paint but I agree a
bit too clan here.

It looks like it has an oval section at the top

It is just a very simple mesh with a uv_mapped picture of a wall close to my
home (a color version for the pigment and a grayscale version for the
bumpmap) :-)

Ah. We have some walls like that around here, and I'd been idly trying
to figure out how to do it in POV without an image map. :-)

Nice image indeed .... one thing of interest to me is the grass. I've also
been using trace to try to cover a heightfield section and make a medow, but
my results haven't been good enough yet. Wonder if you might be willing to
post your method for grass. Perhaps I might learn something and discover why
I'm having so much trouble achieving the look I want.
Thanks Jim

From the thumnail I thought it looked like a photo, when I opened the large
image though I could see it was a render, mainly because of the textures
which I think are too smooth and clean but the modelling is top notch.
Great work.

The grass object is a tuft of grassblades . the trick is I don't rotate it
with rand but with v_turbulence instead. it looks like swirls caused by
wind.
I could post some code but it's rather messy :-)

ahhhh .... just the hint I was looking for ..... I have a blade and clumps
(tufts) that I'm happy with but was using rand to scale and rotate .... so I
will investigate v_turbulence.
Much Thanks

The textures are too clean and the lighting not very realistic but I can't
find why.
In fact I am not after full photorealism.
Thanks for the kind comment :-)

Very nice, I like it a lot.
To get rid of the deformation you mention, you could try to place the camera
farther away from the lighthouse and use a smaller viewing angle (the
'angle' keyword).

Very nice lighthouse.
Coincidently, I am waiting on a render to finish of a lighthouse that I started
working on about a
year ago. It is the Louisbourg lighthouse in Louisbourg, Nova Scotia, Canada. I come
back to it
every now and then, make a few changes, then wait a few days for the "final" render to
complete. I
usually do this when I am not feeling very creative and no new ideas are coming to me.
Anyway, I
may post the current "final" version, if it ever finishes.

I thought of that but I wanted to keep that angle to let some importance to
the background :-)

I had a look a the Nova Scotia Lighthouse Preservation Society site to see
what it looks like.
It is strange how while the function of the tower is the same, the style is
completely different. :-)
Here is a large sampling of French lighthouses

LOL I love these numerous "final" versions

I love the grass! Nice model of the lighthouse too. For me the main problem
is the colour of the lighting, and overall balance of colours in the scene.
The colours on the building at the base of the lighthouse are a bit yellowy
in the light, and green in the shadows. For that kind of sky I'd expect
orangey-pink light and blue shadows. I've messed with it in photoshop (hope
you don't mind) to try to show what I mean.
What gamma setting did you use? It should be assumed_gamma 1, but this scene
feels a bit CG which is often caused by the gamma.
And one final thought, the sky doesn't look bright enough. At the moment the
clouds arent as bright as the white paint on the building, usually the sky
would be brighter than anything else.

I don't mind at all. I agree my version is greenish in the shadows, I prefer
yours though coulds are pinky now :)

Oh well it's Moray default 1.9! I never had a look at this setting

I didn't want to have neither burned whites nor dark paint, maybe I overdid
it
Thank you for your tips :-)

Hello Marc!
Lighthouses remind me a former life (and my study time in Rennes ...). I
used to go near Penmarc'h (pointe de la Torche), and the Eckhmul lighthouse
nearby.
I have a question: how many grassblades did you plant to cover the ground?

Yes that caught my eye as well. Marc turned me onto using vturbulence
instead of using rand to scale and rotate to give some variance. I've
incorporated that into a scene I've been working on for some time now .....
my grass clump count is WAY down. The density I had to use for the effect I
wanted was becoming unmanagable (long parse and render time) for the area I
wanted to cover ..... so I'm a happy camper and yes boys and girls you
should give vturbulence a try ;-)

Nice reference. Thanks!
>LOL I love these numerous "final" versions
Here's the latest "final" version, after 83 hours of render time.
I originally had the idea to have the view be from a ship, and include some of the
ship's deck,
railing, rigging, etc. in the view, but I grew tired of the image before I completed
it. Now, I
revisit it every now and then to play around, usually when I don't have anything else
I'd rather
work on.
I hope you like it!

Yes it's nice
Your rocks look like pillow lava, though, is it a granite pattern? Why not
wrinkles?

You can gain some speed with this version:
f_p_LighthouseIsland(x,y,z).x/10
This works because your pigment is already in shades of gray and all 3
components are equal. Now, you don't have to evaluate all 3 and average them.
This don't work if you use a pigment with a built in color_map like boxo, agate
or wood.
