3 D or not 3 D. That is my question.

I am thinking of buying my husband a 3-D printer for Christmas/Birthday but I know very little about them. I am wondering if it is "too early" to buy one. Do those in the know think they will improve dramatically or decrease in price dramatically so that it make sense to wait? If it does seem like a reasonable purchase, are there ones that stand out for value? (I've attempted to research but I feel like I am out of my element.)

Help with 2D transforms in ellipse drawing algorithm

I'm trying to draw a 3D ellipse with a 2.5D graphics engine (Core Animation layers) which allow me to only compose my ellipse with line segments that must be moved into place using rotations and translations. I'm having trouble with the order of operations and can't get it to draw properly. Any graphics gurus or game programmers out there who can help me? [more inside]

Make Me a Maya Maven

In an effort to improve my work situation and life in general, I have decided that I need to make a slight career adjustment, and that adjustment necessitates that I (re)learn how to use Maya. This scares me because I am so far out of my element since I am 6+ years out of college (where I learned Maya as part of my degree). Assuming all I need is a technical education, where online could I start to learn how to model and animate again? I just want to be able to claim basic proficiency on my resume and not be lying about it.

I want to rebuild my grandparents' house... in miniature

I have a deeply nostalgic love for my grandparents' former home, a generic but beloved split level they lived in from the 1950s to mid 2000s. As an artist and crafter with an obsessive love for details, I have long noodled with the idea of making an incredibly accurate recreation of the house in miniature... but I struggle with where to start. Architectural models, dollhouses? What is the best route forward? [more inside]

3d scan + 3d print = replicator?

Things I would like to reproduce: 1) A very simple place setting that's been discontinued at IKEA (2 spoon sizes, 2 fork sizes & a knife) 2) A simple ceramic bowl my other half made that I broke. :( (Replica doesn't have to be ceramic, just has to be that shape.) Are there any services available that will scan a simple object in 3d and then print a copy of it? Is ZEUS the only way to do it?

3D Printer >$3000?

My wife and I are looking into investing in a 3D printer in the $2-3,000 price range. Can anyone who actually owns one / has used one extensively give any suggestions on brands/models to look at? We're hoping for a basic desktop model with a size capacity of about 8"x8"x8" for making small props, prototypes, etc. Also, what can one expect to pay for the "goop" or whatever they use for a printing medium?

Representations of 'The Phantom Zone' (in the original Superman films)

In the original Superman films General Zod and his accomplices are trapped in The Phantom Zone, which in the films is represented as a 2D 'crystal' prison sent spinning through space. I am looking for any writings/insights into how the visual effects for this were created, and exactly by whom. Any other insights, from comic book lore, about how the Phantom Zone was represented - especially visually - would also be appreciated. [more inside]

I need to animate a tetrahedron

I have Illustrator and intend to make an animated GIF. A tetrahedron is a pyramid with a triangle base. I can't make the 3D extrusion on CS4 agree that I want a pyramid shape. It gave me a triangular prism, though I followed an online tutorial (but that had a square base - which might be part of the problem, and it was for CS3). (No, I don't want to use Flash or download a trial version of Maya but thanks for the thought) So, online free 3D software where I can capture a number of positions of a tetrahedron, and redraw them from within Illustrator? I will need to also place text on each face, so if I can do it in one program only, I'll be happier.

3D Zodiac character items needed

Where can I find good quality stamped or molded _3D_ reproductions of zodiac signs (the fish, goat, scales, etc - not the written characters) of a "classical" appearance, between 1" and 2" diameter? I found several places selling a zodiac candy mold, which might work, but I'm not sure I like the style of the images. I'm wanting to use whatever I find as a pattern for sand-casting metal to make adornments for a big armillary sphere I'm building for my garden, so it doesn't really matter what they're made out of. Tin, plastic, wood, paper - whatever. If they're too flimsy I can make castings of them and use those as patterns. Suggestions would be appreciated. :-)

Do I need to see Avengers in 3D and/or IMAX?

I'm pretty agnostic about 3D and IMAX both. But some films really should be seen 3D (e.g. Avatar) and/or IMAX (e.g. Dark Knight). So...if I view Avengers 2D and/or in non-IMAX, will I be missing out? Each option limits my field of showtime options (and increases expense)...

What are some activities that exercise visual or structural type thinking? Something to do with science, technology, or 3-dimensions preferred. I'm looking for puzzles, hobbies, or other activities that might be performed through an actual job that I'm just not aware of. As examples, auto-mechanics classes and memorizing anatomy books immediately comes to mind.

What is this type of 3D shader / renderer called?

I'm looking for a type of 3D shader / renderer for which I've seen a number of demos. Most featured many objects (in the hundreds), often in greyscale, often with many of the objects acting as light sources. The quality of the renderings is very high, with a beautiful, soft chiaroscuro effect. I have a feeling the technique starts with an 'S'. Any ideas, hive mind?
