 | | Opinions sought on rendering method —Travis Cobbs
|
| | | 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)

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)

| | | | | | | (...) 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 (...)

Otherwise, I think your conclusions about the appearance settings are correct. LDView renderings like your example look great. Would it make (...) (17 years ago, 9-Oct-07, to lugnet.cad.ray, FTX)

| | | | | | | | (...) 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)
