When I was working on the old Type I trainbase 6 x 12,
I also wanted correct wheels for this part. Since I have
these, I tried to create the wheel. In my first attempt
I used primitives only, but the cones looked horrible
when rendered. In my seccond attempt I created a small
segment (of 5.625 degrees) and created a whole wheel
of 64 segments. This part contains over 700 quads and
over 700 lines. In a third attempt I used primitives
for discs, rings and cylinders, and quad-segments for
the cones (64 segments in a circle).
The rendered results can be seen on my question website:
http://home.hetnet.nl/~niels-karsdorp/ldraw/question.htm
(click on the wheels to show a 640x480 POV-Ray render).
Which technique shall I use on my wheels?
(I also planned to create more wheels:
* old train locomotive wheel with spokes
(same as the one above, but a more cone shape,
used to prevent the anti-slip tyres from falling off)
* a wheel like 7039.dat, but with spokes
I also rendered the existing trainwheel (4180D.dat),
yech, that one doesn't look wel... :-(
Wheel 7039.dat has a few gaps, but when tyres are
applied, these gaps become invisible.

| (...) I think Lars Hassing has presented that problem since quite some time ago at his L3P page. I suggest you use the 0 IFPOV method and make two versions of the wheel inside the dat file. /Tore (22 years ago, 15-Oct-02, to lugnet.cad)
