fresnel lense

ronrn · 14-09-2003, 03:51 PM

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.

very cool
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.

Looks cool.

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?

Honki · 15-09-2003, 08:40 PM

Nice scene!
Nice idea too.

Question...

How long did that take to render with all that Refraction????
500 prisms!

ronrn · 16-09-2003, 02:42 AM

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:

ronrn · 16-09-2003, 02:49 AM

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

ronrn · 16-09-2003, 11:01 AM

Oh yea. Lots more work to do on this one.

More detail and texturing to do.
