View Full Version : fresnel lense

Most of my efforts were focused on the lense. No pun intended:)
The lense consist of more than 500 individual prisms. Couldn't decide on a lighthouse setting or a museum indoor setting so I did this one first.

i just dont like the screw thingies when you go up cloise lol, they kinda ruin the realism IMO
the light thingy looks great

Those are steel rivets that hold the glass panels and framework together. I agree they don't work well with the lighting and mat. I'll work on them some more if I decide to keep the outdoor environment. Working on the indoor museum version now.
Thanks for the comments.

Can we have another close up on that lens? Maybe just the lens model by itself? Also a wireframe of the lens would be great too?

Coll, i really like the lense, i just think that maybe ya should give more of a sun burn, "exposure" feel to the lighting, i think it would match up better with the background

really cool, like he said, the lense looks too new and clean.

i would really like to see how it looks in a night shot with the light on
i also agree that your metal isnt cutting it
interesting subject, Ron.
Maybe the glass lenses should be more contrasting, they look a tad greyish.
Will you do a night scene with the lighthouse alight?

Nice idea too.
How long did that take to render with all that Refraction????

Thanks for all the feed back.
I think that these lense themselves are a work of art. Hardly no two are the same. I just couldn't resist modeling one.
I do plan to do a night scene with it fully lit and maybe an animation too.
Most lighthouses are kept in immaculate condition. I even hesitated to add corrosion to the metal. I do however agree that a "dirty" scene sometimes looks better in cg.
Still a bit of work to do on the lightng and the glass mat. So much reflective surface is highly dependent on the environment.
Here is a wire:

Here is a close up. Kind of dull with not much environment to reflect. Thought I would post it anyways since it took 4 hrs to render.:)
This is from the indoor museum setting. Think I will probably stick with it for the still. It seems to suite the composition much better.

hey ronrn, the image looks real cool, and no wonder it took so long to render , with soo many objects :) if u could work more on the light setup, the scene would look awesome
16-09-2003, 11:01 AM
Oh yea. Lots more work to do on this one.:)
More detail and texturing to do.
You might tweak the lighting from outside to cast more on the lenses.

Looks great:D I like the clean look(I'm a clean freak:( :o )on the lense and I think the lighthouse setting looks the best

Thanks again guys. :)
Dan, I will try some renders with more direct lighting like evening or morning light. Taking the lens out ot the shadows just might do the trick.
rubberduck, I will definately be keeping the lense clean.
Inside, outside, WHAT shall I do? Oh well, seeing as I have a good start on both, I guess I'll finish both. Ok AMD, do your stuff:)

Finally got around to the interior view.
Wow - I really like the museum type environment in the last one. It has a lot of atmosphere... Great job.

er..... can i said something that i feel?
will the size a bit weird? i think the real one will be larger?:roll:
hope you don't mind :o

Looks modern but yet its already tilted but I love the lense my mom even said how beautiful your scene was.

Thanks coolguy and MattyG.
MattyG be sure to tell your mom she has great taste:D
fooweng...lighthouse fresnel lenses are catorgorized by size as...1st order, 2nd order , etc...thru 6th order. The 1st order would be the largest of the lenses and the 6th order the smallest. This lense is scaled within a few inches/mm of a 1st order lens, which is about 6 feet+ in height.:)
Here is another version of the lighthouse environment. I tried to improve the textures and lighting quality in this one.
