 | | Opinions sought on rendering method

I'm working on a different rendering method (for instructions) using POV-Ray, and I wanted to get some opinions about the output. On that note, I have two sample renderings in two different sizes, and I'd like to get people's feedback. Note that I'm (...) (17 years ago, 8-Oct-07, to lugnet.cad.ray, FTX)

(...) For me, the keypoint here is "for instructions". Anything that remove legibility to the image should be avoided. In both versions conditional lines are not rendered. Not a huge problem here, could become one on models with many rounded (...) (17 years ago, 8-Oct-07, to lugnet.cad.ray, FTX)

(...) I agree with Philo that the shadows are distracting. I don't think the stud logos are necessary, either. On the other hand, I think the transparent parts in the first rendering look a little too dark. There's also a grainy texture under some (...) (17 years ago, 8-Oct-07, to lugnet.cad.ray, FTX)

(...) - The shadows in version 2 cause color confusion. This is the most glaring example but it is repeated thoughout the rendering: the 1x2 grille piece is white in version 1 but looks grey in version 2. - No conditional lines rendered in both. - (...) (17 years ago, 8-Oct-07, to lugnet.cad.ray)

(...) For instructions I'd definitely choose Version 1, for nice pictures Version 2 minus the hard, black edges and a little less shiny. As the other's have said: - too dark in the black. Actually, to me the whole picture is too dark - which monitor (...) (17 years ago, 8-Oct-07, to lugnet.cad.ray)

(...) Good point. I think the official instructions are harder to follow now with the fancy rendering. Sometimes you can't tell one color from another, especially black, white, and the various shades of gray. I can barely tell the white bricks from (...)

Prefering legibility over realism (though a bit of "realism" is still needed to even recognize the shapes), I put down some universal rules for creating instructions of virtually any (...)

(...) To me, the reasons are mainly "historical": the first way to get better images than the output of Ldraw/MLCad/LeoCAD (which is not that bad for instructions!) was POV-Ray. L3PAO then LPub did a lot to push POV as the renderer of choice. Add to (...) (17 years ago, 9-Oct-07, to lugnet.cad.ray, FTX)
