David Posted February 17, 2004 Share Posted February 17, 2004 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 http://www.cgarchitect.com/forum/filepush.asp?file=Romemall.jpg Link to comment Share on other sites More sharing options...
Tim Nelson Posted February 17, 2004 Share Posted February 17, 2004 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.

Iain Denby Posted February 17, 2004 Share Posted February 17, 2004 That looks really good to me. How have you created it? Link to comment Share on other sites More sharing options...
mbr Posted February 17, 2004 Share Posted February 17, 2004 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. Link to comment Share on other sites More sharing options...
mbr Posted February 17, 2004 Share Posted February 17, 2004 Oops, you already mentioned Bilbao. I'd start by lowering the reflection - it's really more refelctive of light and not so much the surroundings. Link to comment Share on other sites More sharing options...
David Posted February 17, 2004 Author Share Posted February 17, 2004 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 ... Link to comment Share on other sites More sharing options...
Tim Nelson Posted February 17, 2004 Share Posted February 17, 2004 How 'bout trying to get some caustic reflections from the metal onto the surrounding surfaces? Not exactly sure how thats accomplished but I think it might look nice. Link to comment Share on other sites More sharing options...
Tiny Piney Posted February 17, 2004 Share Posted February 17, 2004 Try supersampling the material to reduce the AA problem with the bump map. the image looks great. Link to comment Share on other sites More sharing options...
salf Posted February 17, 2004 Share Posted February 17, 2004 looks great, dont know what to change on the titanium. Well, one thing, on the columns, the sides that are facing towards the camera are black, like theres no light affecting them. Are they covered with titanium also?

David Posted February 17, 2004 Author Share Posted February 17, 2004 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) http://www.cgarchitect.com/forum/filepush.asp?file=Romemall2.jpg Link to comment Share on other sites More sharing options...
SEIF Posted February 17, 2004 Share Posted February 17, 2004 nice job indeed..congrts...but i think the sky colour doesnt match with the colours inside..maybe a pale blue one could be better..also the floor material map is too large..doesnt fit the scale. Otherwise good job...go on.. Link to comment Share on other sites More sharing options...

roly Posted February 19, 2004 Share Posted February 19, 2004 i've been tryin to recreate a material such as yours for some time now, but i cant resovle the bump on the titanuim as well as u. when u painted the bump map im assumingu used photoshop, did u use clouds to generate a bump map? could u please give me a bit more insight on the material. thanks Link to comment Share on other sites More sharing options...

David Posted February 20, 2004 Author Share Posted February 20, 2004 Thank you very much Kingeldar, thats great! Roly, I did pretty much just create a tileable 'clouds' pattern (plus the loint lines) in Photoshop Link to comment Share on other sites More sharing options...
kingeldar Posted February 20, 2004 Share Posted February 20, 2004 did u notice on entrance pic how titanium looks like stone panels (some parts of titanium) Link to comment Share on other sites More sharing options...
salf Posted February 23, 2004 Share Posted February 23, 2004 Originally posted by kingeldar: did u notice on entrance pic 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. Link to comment Share on other sites More sharing options...
kingeldar Posted February 23, 2004 Share Posted February 23, 2004 watch 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....

salf Posted February 23, 2004 Share Posted February 23, 2004 oh, you meant those.....ok ..then youre right, i though you were talking about the other walls (non curves ones) Link to comment Share on other sites More sharing options...
kingeldar Posted February 23, 2004 Share Posted February 23, 2004 no no ok i'm french but i'm not crazy!! we are not all crazy.... in france have black & white pics too if uwant but it's less interesting 4 rendering..... Link to comment Share on other sites More sharing options...
