Of course, producing print-quality images using a real-time
onscreen design program like Bricksmith just wouldn’t work out well; the
images wouldn’t be a high-enough resolution.

The resolution argument actually doesn’t hold up. When I added printing
support to LDView in Windows, I made it generate an image using tiling that
was at the printer’s resolution (or maybe I maxed out at 300DPI; that was
four years ago, so I don’t really remember).

Okay, that puts me in my place. I hereby recant any prior suggestions about
crummy resolution! Now that we have established that OpenGL can produce
print-quality images, my question is: Can OpenGL produce instruction-quality
graphics? Even more germanely, can Bricksmith produce such graphics? I seriously
doubt it.
Usable instructions demand boldly-outlined edges around each part.
Bricksmith doesn’t do that, even more so because it doesn’t even draw
conditional lines. But even if it did, I don’t think part-outlining would begin
to approach what MegaPOV can do, which is to say that it would be well nigh
useless.
LPub, meanwhile, is based on POV-Ray/MegaPOV, so it has little
bearing on whether OpenGL viewers should have built-in image-exporting
abilities. LPub is essentially a way to automate the highly-labor-intensive
render-it-all-by-hand process I use for my own instructions, and can therefore
produce output I would deem acceptable. If you want easy and good instructions
on the Mac, recreate the LPub workflow! Unfortunately, I don’t have the time to
do that; my hands are full enough with an LDraw editor. But it would be
fantastic if someone could do it, because I’m the first to admit that my way
stinks.

| (...) For what it's worth, I don't think most people are aware that OpenGL can be used to render images at arbitrary resolutions. Most video cards don't support rendering directly above 2048x2048.
