A while ago I made a wheel for a building site dumper (one of those little ride-on things like a oversized powered wheelbarrow) (sometimes called "guinea Cadillac" in USA, I was told). It is in the Poser Fun Stuff. It is only 1492 polygons, and its tyre is all one "bag" of polygons, and not as often with each bit of the tread as a separate box of polygons. (I looked at a dumper on a building site and made a map of its tyre tread and wrote a C++ program to output the .OBJ file accordingly.)

I think "guinea cadillac" may be an ethnic slur, in anycase it might be a good Idea to avoid the phrase just in case ;-) -JH.

Anthony, I'm pleased to hear that your C++ program worked. I considered doing something similar but I first tried creating an obj file by hand using a text editor (having done a lot of trigonometry to work out the coordinates) and found after a few hours that it didn't work. Inspired by your success I'll have another go. Jeff, do you think he meant that the Cadillac came from Guinea, or maybe New Guinea?

I'm almost sure the term is a slur against people of Italian heritage. I have been wrong in the past ;-0 -JH.

Does this mean we can't say guinea pig anymore either?

There is NOTHING racial here. Guinea is a part of Eest Africa indeed. The reference is to the area, not to its population. Some gold likely came from there; the only common meaning of "guinea" in England was a gold coin worth 1 pound 1 shilling (modern 1.05 pounds), perhaps originally made in Guinea or from gold from Guinea, and it became a posh word for the sum of 1.05 pounds. - The guinea pig alias cavy didn't come from Guinea but from Peru and Bolivia. - The intended meaning of "guinea" in "guinea Cadillac" is clearly "cheap, simple", referring to the British guinea amount of money.
