Still Life with Glass Cross
« on: March 28, 2015, 06:29:33 pm »

I'm trying to get a feel for rendering with the ray tracer. I would really like to get deeper shadows and intensify the ambient occlusion effect at the same time. Suggestions or comments?

Sorry, not up with shadows or ambient occlusion, but would like to comment.
 Those curtains at the back look really cool, but the texturing on the box looks a bit 'off' ?

Hi Johnar,

Actually I just swapped the picture for a new render that I like a bit better. I thought probably no one had seen it yet. I didn't change the texture on the box though and it is really not very good.  Are you referring to the texture itself, or the way it is applied?

OK Johnar, what about this one?

 Someone else may be more helpfull about the box texturing. To me, it 'somehow' still doesn't look quite right?  (maybe the texture itself.... really not 100% sure)
 The keyhole  doesn't look at all real, so if you're after some realism, that would need some attention too.  :)
 And, the cross is glass, sweet, but what would you say the stand is made out of?
 Its shiny, cool stuff, but can't name it. Have you tried brass, or stainless steel?. (or maybe just something 'recognisable'.  If i was told to name what the stand was made from, i would have to say "some type of shiny plastic?"....
Just thinking out loud really........... :)

The escutcheon is upside down Ron! (Five years in the Locksmith Trade many moons ago tells me that!)

I have been quietly following this thread, really nice work Ronald. Regarding the box, I think what makes it look a bit odd is that the grain of the timber wraps around the front, sides and back.  This makes it look as if a thin veneer or self-adhesive woodgrain vinyl has been wrapped around the box, rather than appearing made from timber panels.  I would tweak the UV coords of the side faces of the box, inside and out, to shift the grain such that it no longer lines up perfectly at the corners, which should reduce this illusion.

You could also consider the construction of the box itself.  With the current design each panel would need to be bevelled to 45 degrees at the ends and glued and/or pinned together, and while this is certainly an effective construction technique it would most likely result in a slight gap or irregularity at the corners since it would be difficult to work wood to achieve a perfectly sharp edge.  Perhaps the construction could be simpler, showing the ends of the front panels in the side faces, like this: http://cdn.shopify.com/s/files/1/0042/2962/products/deloraine-stripy-myrtle-two-layer-jewellery-box-1_1024x1024.jpg?v=1323229306, with an end-grain texture in the narrow faces, or even simulating dovetailing like this: http://www.simonzablotsky.com.au/timber/gallery3_14_58_enl.jpg might help improve realism.

I would also render a separate greyscale AO layer that can be combined with the original image in something like Photoshop or Gimp, this would allow you to control the intensity of the AO shadows.  Creating a similar layer for actual shadows could also be considered.  It is generally a bit tricky to get a really well balanced render directly from any renderer, creating separate layers and combining outside of Anim8or is a good way to gain additional control over the output and is pretty much standard practice for many applications.

Once again, always great to see some fine work being done with Anim8or, sometimes I forget how impressive the ART renderer can be.

I see what you mean about the textures, ENSONIQ5. I tried to fix them so that they don't wrap around the corners. Also, I rounded the corners a bit hoping to make the panels seem more solid. It is very difficult to introduce small imperfections like gaps in the joints that would lend realism. Here is a render of just the box:





Kreator: I am working on the new escutcheon.  I had to google "escutcheon"--and I thought I had a pretty good vocabulary.  :)

I have to admit, I gave a 'Wow!" when I saw the revised box.  The wood texture is absolutely perfect in my opinion, this image is as close to photographic as any I've seen rendered in Anim8or.  Utterly convincing, if not for the familiar checkered floor plane I'd suspect shenanigans (eg. rendered in Kerkythea or some such).  A huge improvement, which may also have something to do with the lighting.  The earlier image with the cross seems a bit flat and dull by comparison, perhaps some warmer lights to bring out the colours of the timber and brass?  In any case, I can suggest no improvements to the box (other than the escutcheon of course!) and my hat's off to you, sir.

Yup, ron, Like ensoniq said... That render makes a nicely modelled, very well-texture design like that look incredible. Keep up this awesome work!

Not buying it. You just emptied out your jewelry box and took a picture of it on a tile floor.

Actually ronald I am curious- how'd you get that really realistic specular shine? It's looks so convincing!

Can't argue with awesome.

 Texturing looks pretty perfect, and great render.
 Nice one ronaldefarmer

Thanks for the encouraging remarks, everyone.

Davdud101: About the specular shine, the wood material has a specular value of 1.6, roughness of 4, and bumpmap at 22 percent--same texture as diffuse. In the scene editor, global lighting is at 0.32 and ambient at 2.65. It still isn't exactly the way I wanted it.

Here is my latest render with a new and correctly oriented escutcheon:
