Hello,

 

This is my first real attempt at trying to simulate a titanium material. Does it look ok, or is it a bit iffy?

 

Has anyone really 'nailed' this technique, or could anyone point me towards a good tutorial - I'm pretty much trying to simulate a 'Guggenheim Bilbao' kind of effect. I'm using VIZ 4.

 

thanks in advance,

 

David

GREAT JOB! I love that material. If I could pick one thing about it I might change, it might be the joint size. Right now it kind of looks like a cmu joint, so maybe if you tighten it up a little it would look better. Then again I'm no titanium plate expert so how do i know?

 

Nice rendering.

It looks good, but more like aluminum or stainless steel.

 

Titanium has more of a soft golden color to it, and, in most cases, will not bend that much (like aluminum). Take a look at Frank Gehry's Guggenheim in Bilbao to see where titanium gained it's glory as a material for architecture (although I've loved it since they started crafting bike from the tubes!).

 

It looks nice, though.

Thanks for your responses!

 

The material is just a painted tileable bump map and a raytraced reflection ... shouldn't be too much bother to reduce the joint size, so I'll try that.

 

One of the problems with using Bilbao as a reference is that it's an exterior, and (in most photos I've seen) is receiving intense direct sunlight. This is an interior with a reasonable amount of diffuse lighting, and I can't think of any interior examples I've seen that I could use as reference (anyone?!)

 

Maybe the reflection needs to blur more so that it looks less mirror like ...

Ok, I've updated this with less defined joints and also a warmer tint to the material.

 

How do you think it compares to the original? Is it an improvement or have I lost something? (I'm not sure, I quite like both looks for different reasons!)

 

(I'm going to have to go back and look at those black columns, they should be titanium too)

how titanium looks like stone panels (some parts of titanium)

¿?

 

Well, i havent go to Bilbao, and you did, but........are you sure? I mean, if youre talking about the first pic you posted, titanium is used in the "organic curved" shapes, but the rest is stone, i mean the non-curved walls.

 

Then again, im saying this by looking at the pictures, i havent been there, so i might be wrong.

some plates look like stone cause it reflects stone almost perfectly... said that cause it will be hard to get same properties in ur render (i mean i would have many troubles trying to, but maybe it will be more easy to u , i'm not very experienced in rendering....

i definetly think you are on the right path here. i would lower the reflection, and use a filter or something to blur the reflection.

 

also, i would work on your people some more. the girl sitting in front lacks the contrast the others have, and the photo was taken while she was int he sun.

 

i would lose the girl and her grandmother on the right completely.

 

...and the lady walking on the left, and the man behind her. there shadow is half in the bldg shadow, and half in the sun, but the actual image of the person is completely in the sun. if you selected the appropriate areas on each of those figures, you might be able to do a levels or something on them, and make it look like they are only half in the sun, rather than all the way.

 

..and the 2 girls to the left of the man do not have a shadow at all.
