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. (Presumably the new cards that support 2560x1600 (...) (19 years ago, 4-Apr-06, to lugnet.cad.dev.mac, FTX)
