I’m not sure I 100% understand your goal(s), but I think what you need is:
All white shading with all black edges.
This way the (OpenGL) ‘Z-Buffer’ does all the hard work for you.
Maybe travis could implement it in LDView, (or just make all LDraw parts
white in your model).
|
You are right that I can approximate it simply by making all the parts white
(as shown). However, shaded white is not really white. Every angle of white
reflecting to the camera is actually a different shade of gray. I really
want no shading at all.
|
Have you tried disabling lighting?

I’m looking for something more like you would see in a patent or in technical
literature.

The ‘almost there’ picture you posted is really cool so I also wouldn’t mind
a LDView feature doing that on the fly.
But if you want a real fragment free vector representation you need some
sort of file format and tool(s) to display it. Maybe you could get that by
using a pov-ray export as a starting point, there are more pov-ray
converters then LDraw converters :)
|
Exactly! There are any number of good formats including CGM and WMF, and I
already have tools (like Canvas or Illustrator) to display and edit them.
I do plenty of POV-Ray work, but since POV-Ray is all surfaces, there are no
edges. In a way it is the opposite of what I need. If there was a such
thing as a VIEWER for POV-Ray surfaces, that might do the trick. But there
is no such thing that I’m aware of.

I don’t know any ether, I’m sorry.

| (...) Wow do I feel stupid. No, I hadn't tried that, and it works perfectly. It's still not a vector image, but at least it gets me to a good raster image in one step instead of five. It is a bit counter-intuitive to me that the way to get a good (...) (14 years ago, 24-May-11, to lugnet.cad, FTX)
