Either

a) you're lying, and this is not a photograph, but another render....

or

b) You've crossed into the nexus between reality and POV-Ray

because it really IS hard to tell where one ends and the other begins.

Haha. ...yes, my reality is in question - according to my doctor. :>0
Maybe I should take the Red-pill next time.

I agree with Bill. How do you *achieve* all of this amazing 
modelling/scene building? I cannot even dream about equalling your 
quality work...

Thank you. Too kind. I do enjoy the modeling and scene building. I tend to look
at the world as "how would I model that!"....and then get all excited about
modeling it (without triangles). :)

As far as the quality, I would say most of that is the excellent programming and
development that has gone into POV - which I had nothing to do with.
After 30 plus years, I'm still amazed with POV.

Yes indeed, and you are a master at texturing/uv-mapping your objects. 
Personally, much of /that/ work I do with the help of dedicated 
modellers (mainly Silo), others here would probably mention Blender at 
this stage. Do you use those or do you all the modelling in POV-Ray?

Still, when I examine for instance your jacks workbench scene, I am 
absolutely overcome by the quality of the lighting. And somehow, it 
looks so /casual/ that I wonder where the trick is hidden. Lighting a 
scene is - at least for me - something not /casual/ at all!

Thanks for the kudos.
When I jumped back into POV, I was using 3DS Max to export some object types to
assist in modeling and object placement. Recently, I moved to Blender once I
realized I could export & convert almost all of the object types through the
..x3D file format. I wrote a small translator and now use it frequently for
object/scene building.

In Blender, I always start with an image underlay.
I use naming conventions to sort the POV object types. I currently convert
spheres, boxes, round_boxes, cylinders, torus, blobs, points for prisms, lathes,
sweeps, and position arrays.

Yesterday, I modeled a gearbox for Jack's brain. I found an image that was
approximately what I had in mind. I screened it back and adding some guide-lines
before importing to Blender. I used spheres renames as pointData for position
arrays and use cubes renamed as RBox to export as POV Round_Box(), etc...

In POV, I use the pointData array in a loop to punch holes in the frame, and
place the gears, and used the Round_Boxes to create and void cut the frame body.

Attached shows the Blender file, the data dump, and 2 test renders.
Always a work in progress. :)

As for lighting, it's lots of test renderings. :)
Start with no lights and a few objects to confirm the global ambient - try to
use as little as possible. Use a sky sphere imaged close to the final
environment lighting unless your scene is fully enclosed.

Position the camera close to the intended view. Add each light 1 one at a time
starting with the most dominate. Hide all scene objects and add a few
materialized spheres on a floor plane in front of the camera to determine light
intensity, color, shadow direction, and reflections. I use a chrome sphere and
another with a satin bumpy finish. Look at the bump and phong positions to
verify that the light direction looks good. Never position lights behind the
camera. I like to have good definition between 'light-side/dark-side' on
objects. If the dominate light is from the right, add a softer fill/bounded
light from the left. I try to use 2 light to fill a scene and sometimes a very
weak under-light (no shadow) to fake bounced light from below the camera. If the
scene is starting to look over-lit, hide all the lights and add them back in one
at a time with less intensity. ...and lots of test renderings. :>)

Render on - I love what you have going on in your current scene.
Mike

Thanks indeed, Mike, for your detailed explanation. It is always 
refreshing and enlightening to learn from others how they approach and 
solve puzzles and problems which, I am sure, are so familiar to most of 
us. I shall have to carefully re-read this: some solutions are familiar 
to me as I follow more or less the same path/approach, others are new 
and intriguing. Where lighting is concerned, I very much lean on 
radiosity to help me fill the lighted space, sometimes adding small 
fill-ins where difficulties appear... and it is lots of test renders 
indeed!

Holy...diddly! /8---------O\

I'm speechless! :D Excuse me, now have to try and find my chin that just dropped
somewhere here on the floor, huuaah! :D

And gotta have some pills too; red, blue, dried frog, anything goes at this
point. xD

Thanks, I have not worked with POV's radiosity much. It can be very slow on
complex scenes. I've been able to 'fake-it' with using only area lights. I'm
sure I need to upgrade my hardware...requires wife intervention. ugg.

I mentioned 'no light' behind the camera...I meant the lights' view of the scene
is close to the cameras' view. Can make for bad renderings.

I just posted the scene file for the attached gear box image. It will show how
the Blender export is being used to construct the parts. If you use Blender and
think you have use for the .x3D to POV executes, you're free to use them.

Mike.
