What I'm asking is, when you perform a command like
MAKE OBJECT PLAIN 1,2,2
How many pixels are there within a object face? I ask because I'm working on my user interface using MS Paint, and I usually decide size by pixel. However, I know that a 2 by 2 plain isn't 2 by 2 pixels, so what is it's size? Is there a conversion rate one could let me know of, such as 1 object size = 100 pixels?

well, that all depends on the object's distance from the camera. Pixels are tiny square making up your monitor's image, in 2D. Pixels aren't for 3D measurement.(maybe voxels?) If you want your plane's size of 2x2 to really show up as 2x2 pixels, position your plain at N units from the camera. N = screenheight() * 0.83. voila!

I think it's Texels, but I'm not 100% sure about that.

it all depend on how big the 2x2 plain will look. (how close to camera it will be) 2x2 texture will still always cover the whole plain, it's just that when you get close enough to the plain, (like it would cover 60x60 pixel size on the screen) it would just look blurry, because the colours of the screen pixels will be interpolated from the texture.so if you had one white on the left and black on the right, it would probably end up looking more like a blurry, gray gradient if zoomed close enough. Unless you turn off the filtering. (not recommended)

That is true, I had forgotten the camera influences a 3d objects size. However, with the formulae you gave me, phaelax, it should be easier to determine how big to make the plain. Also, I knew of the streching habits of the textures, las6. That was in part the problem, for if the texture did not fit right on the plain, I'd have a funky looking UI. Thanks for the help all.
