with lathe items for the more complex curves. Example (dimensions scaled
from a real chess piece):
#declare Pawn = union {
cylinder { <0, 0, 0>, <0, 3, 0>, 11.5 }
lathe {
cubic_spline
7,
<5.5, 2>, <10.5, 3>, <11.5, 5.5>, <11, 8>, <8.5, 11>, <7.75, 13.5>,
<8, 16>
}
cylinder { <0, 13.49, 0>, <0, 13.5, 0>, 7.75 }
lathe {
quadratic_spline
3,
<12, 12.5>, <6, 13.5>, <3, 27>
}
lathe {
linear_spline
3,
<3, 27>, <7.5, 30>, <3, 33>
}
sphere { <0, 39, 0>, 7 }
scale 0.4
translate <10, 0, 30>
}
file, where you can play with an object and do lots of changes and quick
renders before pasting the final code into your main scene.
