i know that the torus generator generated part looks kind of shit but i know nothing about circular maths (trig?). steve tells me that the helipad and road curve 7 studs have both been made with the generator... have you seen those yet tery? do they suffer the same problems? here is what i will do: i will make the 8-stud unpatterened road plates completly in color #16. i will also make the patterned 8-stud straight, t-junction and cross. i will use the torus generator to generate the small curves on the corners. i will hardcode the road surface itself as well as the area just outside the green lines where there are no studs in color #7 i will make the area under the studs color #17. this will allow people to use them in green. i will submit all these parts. i will submit the curve as posted to cad.dat with the extra studs removed unless i can figure out a bettre way to do it. i say we see what the ldraw community at large thinks about the part. if they are happy with the use of the torus generator then that is ok. if they vote it down then that will prove that the torus generator should not be used for large curves. no-one has ldrawn any part that requires large curves yet so i have nothing to go on except steves parts, made with his torus generator. i have not seen those so i do not know what the quality is like...

(...) I didn't use the torus generator program on the new parts. I wrote a couple of Visual Basic routines that I used on the new pieces, which generate circular rings and edges. I've included the routines below, but I haven't done anything to (...) (26 years ago, 6-Apr-99, to lugnet.cad.dev)

(...) In the absence of example, surely you still have common sense to go on? Approximating a very large circle using increments of pi/12 radians either isn't appealing to common sense or shows a lack of common sense. --Todd (26 years ago, 6-Apr-99, to lugnet.cad.dev)

(...) Unless you're 14 years old, that's very sad. (...) You would ask the community to lower its standards of quality rather than raising your own? --Todd (26 years ago, 6-Apr-99, to lugnet.cad.dev)

		Re: baseplate 32 x 32 road curve with road pattern-9 studs
(...) First of all, it's been 12 years since I last did any higher level math, my junior year in high school when I did trig. So I don't think there's any shame in not knowing (or remembering) anything about it. Then again, I don't think that (...) (26 years ago, 7-Apr-99, to lugnet.cad.dev)

		Re: baseplate 32 x 32 road curve with road pattern-9 studs
(...) "Kind of" is a gross understatement. If the parts Steve sent me were done using the torus generator, then he did a LOT of very careful post-processing. Steve would _NEVER_ send me a part that looked like the baseplate you posted in cad.dat. (...) (26 years ago, 7-Apr-99, to lugnet.cad.dev)

(...) I'm thinkin' maybe the torus generator was designed with smaller parts in mind, where the coarse angular granularity is far less noticeable than on a baseplate. What other mathematical methods of generating coordinates on a circle do you know (...) (26 years ago, 6-Apr-99, to lugnet.cad.dev)
