[ COMPLETE ] Challenge #2: Render Glasses Using ART
ENSONIQ5:
The entire shadow is a texture (as you guessed) applied to a plane that sits just above the decking surface. The texture itself is just a black square, with bluish areas where the lenses would be. The actual shape of the shadow, and the level of tinting projected through the lenses, is controlled by a transparency map. The shape of the texture and trans map were defined by running a quick render with a camera positioned with the same orientation as the light source. The trans map was 2D edited to provide a soft shadow effect.
Rendering this with real shadows would have taken many times longer to render (as it is it took about 8 hours) and the caustics effect could not have been done at all. Manipulating the textured plane to sit correctly was a bit of a fiddle, but as an experiment the concept works reasonably well IMO. I have noticed a couple of minor modelling errors that will need fixing, so a re-render will be required, which should be up in 24 hours or so.
Steve:
There's some nice work here. (3.5 *days* to render, $imon??? I need to speed ART up a bit!)
siragin:
I just started this tonight. I still have alot to do to it and I might not finish by the deadline. I have to much other stuff to do but hopefully I will finish in time. Also this was not rendered in ART. Ill do that when I finish modeling it.
lynn22:
I just fnished my entry, one straightforward render and no post-processing.
Edit : I just popped out and bought a new table ;D
$imon, the reflections are the natural result of the glass material attribute specular/glossy when a simple plane is put in front of it showing the image of a brightly lit window, just like in the real world.
$imon:
onespirit; thats looking a lot better already! can't wait to see the final render! Just a note for the gold material , maybe you can give it a little bit more reflection, and make the color a bit less yellow! just a thought..
baxter; that looks nice and simple! good use of ART :)
Thanks neirao!
Ensoniq; great glasses ! the actual glass part is sticking a bit through the frame, but that was probably what you were tlaking about fixing.
Because youre using a texture to create the shadow, the shadow is of quite low quality and maybe a bit too smooth at the bottom. Maybe you could try using a higher resolution texture? or mixing the texture with real shadows..
Steve: haha it would be awesome if you could speed it up of course! But i pushed anim8or around a bit too.. 144 AA samples with dielectric materials , a lot of glossy materials and an environmental map around it for reflections.. so its partially my fault ;)
Siragin: Good start! nice style.. i hope we'll get to see an ART render!
Lynn: that looks excellent! How did you create the reflections?
The only flaw seems to be the wood texture though, maybe you could scale it down or get a higher resolution texture somewhere?
You're right Hiho, a lot of very nice entries here!
