Beautiful!

MaximumPC did a story on SU

Interesting!

Are those entities above the sick mirrors?

Also, the sink looks like it could be used from everything from a sink to a urinal (lower part) to a butcher's basin. Just make sure the white grout has plenty of sealer!

Very, very nice shwetabhseth.

I would agree on the wine in the glass color being a bit off, and the white of the cigarettes being too washed out.

But the care you took for the inside lid is awesome.

Very nice collection Liam.

You're a busy fellow!

One odd thing though, that walkers profile is quite suggestive.

By the way, your elevator made me think of a game I played 7 years ago or so, called I-War, Independence War.
Far and away the most physics-realistic game...probably to this day. Anyway, it has a cool elevator in the game.

Most excellent shareck.

The subtle flapping and jerkiness of the tank's track where it re-engages the guide wheels is awesome.

I think he means the wireframe. View/Facestyle/Wireframe

Very nice boofredlay.

Clean and innovative.

Although after a few glasses of scotch, the difference in the pieces could get 'subjective' after a mate to say the least.

Very cool choice for your first post!

Very interesting. The second one reminds me, for some reason, of one of the floating cities in Larry Niven's Ringworld Engineers

I'm a little confused.

I read through the front end brief description of the rules, and also the pdf that goes into greater detail. I found nothing about what g forces are to be maintained on the riders. . .or not exceeded. . .positive, negative, lateral.

Did I miss something, or is this just a contest to make the most whimsical looking contraption possible?

Basically I experimented endlessly with different "eyepieces" and refraction indexes. THIS site helped me develop some basic shapes. But to be honest, simple mirrored arcs for lenses will suffice IF you keep the lens as shallow as possible. However, the below pics were a bit harder because I needed to get the parabolic shape of the main mirror close to perfect. . .or as in the "the real world", get the wavelength error within several angstroms of, say, yellow light. A "real" telescope mirror has to be MUCH more accurate than what I am doing of course.

Here's a "newtonian" type setup.

I've 'cheated' slightly here, in that I am not using eyepieces, and only letting the focus point of the image impact at the receiver plate. This would not allow a 'virtual eye' to see the image, as the image is crossing at the plate plane, and not traveling parallel. The imaged "SketchUp Indigo" was very close to the reflector. The ratio from the image to the receiver plate in comparison to the receiver plate to the top of the sagitta of the parabola is a modest 6 to 1, so I get a nice crisp image.

The below pic starts to show the error either in Indigo's ray tracing algorithm or the preciseness of my parabolic surface. I imagine it's my inability to draw an exact parabolic surface. The ratio here is a huge 320 to 1. Not much for a real optical system, but still kinda impressive in a virtual environment, not designed to do such.

That's facinating...how did you know it was even possible?

I have a couple of telescopes, and saw early on the wonderful reflections in the chrome material and the clean refractory attribute capabilities of Indigo, and most other rendering engines, and thought I'd give it a try. However, it wasn't till I was familiar with Indigo that I thought I might be able to do it

After much experimentation with Indigo's refraction index, off and on, for quite some time, I've managed to re-image an object entity in SU through a refractor-type optical system using Indigo. I used a modified Kellner-type eyepiece, more closely resembling a RKE.

Here's the object I imaged and the optical setup in the distance. The distance ratio of the object (the red slashed square) to the objective lens in relation to the objective and the 'eyepiece assembly plate' is 16 to 1.

Here's a view of the objective lens and the eyepiece assembly.

And the focusing or eyepiece assembly. I've changed the lenses to monochrome so they can be seen.

And finally the rendered image on the receiving plate.

I will also post a reflector type system where I've gotten MUCH better imaging results.

Oh... by no means was I complaining.

You've done a great job here!

Thanks everyone!

But what do you mean "most of your posts are gone"?
I cannot remember any "issues" lately

Oh, I mean WAY far back... like 18 months ago back.

Hi Everyone-
Been a long time since I've posted. I see most of my posts are gone, I guess from the forum revamping.

Been helping a fellow with some redesigns on the 1998 classic game 'BattleZone' that was recently re-worked in BattleZone Enhanced v1.11. IF you are familiar with the original, the added ships and maps are amazing. The ship control algorithms are what kept me interested all these years... seeing how BZE is a full game and is now free for the download and the online server is also free.

Didn't see this mentioned in the thread, however, I may have missed it.

If you're working in tight and especially inside detailed areas, create a scene saving that perspective and position. If you get turned around and disoriented, you can quickly return to the view.

Opps. . .thought was a general place for youtube vids.

My two cents is when you pick a video card, pick one that support dx10 such as the nvidia 8800 GTS.
