I am not getting lpub to generate nice edges.
At this picture the windscreen is a blob with edges only around it:

And the wheel hubs have a series of ugly black dots:

Does anyone know the right parameters to get well defined edges?

Paulo, the “right parameters” depends on what size resolution you are
creating your BIs.
I use a 1600x1200 image resolution for me BIs and then shrink them to
whatever I need.
Based on a 1600x1200 res, I have found that these parameters work good.
2, //depth difference required for line
0.35, //angle difference required for line
0.2, //color difference required for line
1.2, // 2.0 default line width

You should note that the value for the line width is relative to the resolution
of the image, not relative to the size of the object being rendered. So, if you
render a brick that takes up almost all of the space in your image, your line
will appear thin relative to the brick, where if you have a rendering of a brick
that is very far from the camera, the line will appear thick relative to the
brick.
