Transparent display stands
« on: November 09, 2008, 07:04:17 pm »

In the Scanline version of my museum I had the objects displayed on cubes and tubes to keep them off the ground.
However, I found the rooms too cluttered. Now, in ART, I have transparent display stands for each object.

What do you think, crits welcome.

I like the refraction on those stands. I can't compare to what the first look like, but these look very nice. Maybe use a bit lower int value (your using dielectic right?).

Floyd, the first version, in Scanline, had just plain cubes and tubes (as below).

I'm not using dielectric but class : transparent, IOR : 1.21

I do find the newer version much more attractive.
I think you should look into modeling the curtains though, they don't look realistic at all currently.

Though honestly the way your museum is set up makes it look like the inside of a home.  I think it has to do with the window/curtain style and door style.

Nice images lynn22.  I would agree with Hiho's comment regarding the curtains, modelling them would look better, especially across the top.  Extruding a bendy spline curve in the Y direction would do the trick.

My only other crit regards the glass stands.  From a manufacturing point of view, I am not sure such sharp angles would be possible, unless the stands were fabricated from 3 separate pieces of glass.  I would expect the stands to be made from a single piece, heated and bent in two places to form the stand, and as such I would expect the corners to be smoother, a more gentle curve with a larger radius.  It is a minor crit, but as you have clearly put considerable thought into the materials and construction of the museum I figured it was a valid one.  Really nice work, I particularly like the door.  Modelled or bump mapped?

Very nice lynn  I'm thinking more antique wood like black walnut
also maybe try double pained glass for more reflection also maybe
a few more reflections of the art work in the glass.
(nice art work by the waY)

Great work, your skills are really coming along. Seems that you have to work on the rest of the scene slightly to bring it up to the level of the stands. Especilly the weird light on the window etc. The vases could do with a little spec reflection now.

Thanks everyone, much appreciated, I didn't expect that many reactions :)

hihosilver & ENSONIQ5 : you are right about the curtains, I didn't like them either but I have to compromise on keeping the number of faces down. When it takes 14 min. to render the image below, and I expect to render several thousand, then "every little helps" :)
Anyway, they were too bad so I changed them, very good tip ENSONIQ5.

hihosilver : the museum is in a little colonial building, just a local collection and not part of the British or Metropolitan hence the homely decor.

ENSONIQ5 : I had a small curve at the edge of the stands but obviously not prominent enough, I changed that.
The door is a plain box frame with bumpmap for the same reason as above.

Irv : I did try to get the reflection of a pot in the window in a close-up but it didn't work. The reflection was too big and upside down.

headwax : sorry, I can't see what you mean by weird light on the window, can you give some more detail please.
The Greek vases have a little bit of spec - which is best seen in close-up - but not too much for they are very old and the shininess has worn off.  ;)

Those new curtains look way better. Those few extra poly's won't save your hours of rendering. Rendering with shadows and AA will.
Maybe the wall could have some materials, they look a bit flat and boring right now. Maybe a slight bumpmapping will do, but only a slight ^^
The vases look good, i like the material on those greek vases.

I love the stands, they look great.

The vases and pictures on the wall look superb.

My main crit would be (and I encountered this myself those times I attempted to do an interior room) is that the border between floor/wall and celing wall looks too perfect, because well, it is a perfect line.

I'd put a tiny curve there or, even better, some crown and baseboard molding would really cap it off great.

Sorry for being obtuse lynn!

The lighting setup in the shot is giving dark nicely defined shadows. This indicates a dominant intense source of light. It's not likely however to be as bright as the light outside. I think you would find some darker shadows on the window wood, not just the architrave, specially in the bevels. Probably a small bump map would help.

I think the specular reflection on that right hand urn needs to be increased because of the lght source indicated by the shadows. Specular reflection in this case being a small bright area of light cooincident to the line of light as would be seen to be reflected from a perfect mirror.

Amyways, that's my opinion.

It's your museum. Great work!

That is a big improvement Lynn22, the curtains look much better and I think the larger radius curve on the stands looks more convincing.  The skirting boards (twixt floor and wall) improve the image considerably, and perhaps (as mentioned by Olias) a plaster moulding between wall and ceiling would also help.  I understand the need to keep polys low, but as previously mentioned it really is shadows/lights/AA that slow things down more than poly count.  I guess it is a case of balancing realism against the very real need to keep render times down, especially for animations.  Anyway, really great work and I look forward to seeing this project unfold.

Thanks again guys !
I guess that I have the set-up finalized now .... or not ? See below (the second room)  ;)

floyd86 : I tried the wall bumpmap but then the walls demand too much attention and distract the viewer from looking at the objects on display. It's a good idea that I will keep for another project.

Olias & ENSONIQ5 : I added the plaster moulding and it looks better, it "frames" the picture.

headwax : you never, I am the obtuse one for I didn't get what you meant ;D
I cranked up the specular and specially in a close-up it makes all the difference.
