Any idea why the some pieces don’t show seams in POV-Ray but they do in
MLCad? Sorry if this has been addressed elsewhere. I did search for it, but
I didn’t find anything. (Newbie to all this.)
For example, this is the model as seen in MLCAD. (Notice the forklift has
defined lines between the rails and the forklift platform.)
And this is the same model after being run through POV-Ray 3.6 (Notice there
is no visible seam between the rails and the platform piece.)
Thanks for you help.

Hi David,
The short answer is that there are no seams, only lines. Since a line is a
one-dimensional object it is invisible in POVray.
The long answer is that POVray won’t show edge lines because they are not really
useful and don’t fit with the purposes of a raytracer. A raytracer exists to
mimic the real world and in the real world there is no such thing as an edge
line. MEGApov used to have an edge-finder routine but I think it’s been dropped
as not being particularly valid for a raytracer. If you want to render
instructions or such you should use LDview/ldglite.and you will get the lines.
If you want to make ‘realistic’ renders you should use POVray.

| (...) Thanks for the quick response. But I'm still confused about something. If POV-Ray doesn't draw lines/seams, then what causes the other parts to display seams in the POV-Ray picture? (Such as the supporting bricks for the forklift rails) Thanks (...) (18 years ago, 24-Sep-06, to lugnet.people.newbie, lugnet.cad.ray, FTX)
