Yep.
-p Don’t substitute any primitives in the P directory with POV equivalents
---------------------------------------------------------------------------
In order to have a nicer looking image some parts (primitives) in the P
directory are by default substituted with POV equivalents. E.g. 4-4cyli.dat
is substituted by the POV object “cylinder 0,0,0, 0,1,0, 1 open ”.
In this way you will see a true cylinder and not a crude 16 edged one.
Also you will typically get a 10-20% increase in rendering speed.
Currently 49 primitives are substituted with POV equivalents.
You can see their names by executing “l3p -pp”.Thanks for the quick response!

Sorry! I guess I didn’t make my question clear enough. I’d like to substitute
the primitives still, but with those of my own creation, rather than those that
L3P creates. For example I think a stud looks better with a slightly rounded top
(a combination of a cylinder and a cut-off cone) rather than just a cylinder. I
can do this by overriding the default #define statements by a later one but this
can’t be automated easily.
A second question I just though of is how can one introduce redefinitions using
IFPOV metastatements? That is probably easier as I suspect the original source
code of L3P would have to be changed to do what I’d like.
Thanks for your help though,
Tim

| (...) You got it. 0 L3P IFPOV meta-statements are probably the way to accomplish what you want. Hmm, thinking more about it (I could just go try it), you'll probably still need l3p's -p parameter, or l3p probably won't even look at the primitive (...) (20 years ago, 12-Apr-05, to lugnet.cad.ray)
