 | | Lines in patterns
|
|
When making lots of parts BFC compliant I noticed that many parts have lines in the patterns. Most of these lines are surrounded by polygons. What is the use of lines in (flat) patterns? (L3P/POV ignore lines, right?) Am I right if I think that (...) (22 years ago, 3-Jan-03, to lugnet.cad)

(...) The lines are there to have something drawn when the polygon would otherwise be too small to be rendered (at low magnification). Personally I don't like them in the present form, because they rely on renderers to draw objects in a certain (...) (22 years ago, 3-Jan-03, to lugnet.cad)

(...) Why should a renderer *NOT* draw lines last? Original LDraw did (IMMSMR). Better fix the renderers once than to burden the part authors with yet another META command each time they make a patterned part. Those lines in patterns served a good (...) (22 years ago, 3-Jan-03, to lugnet.cad)

(...) Many renderers do transparency in a great looking way, that is not compatible with original LDraw... Think of the LDraw format as a 3D format usable in many contexts. It should not be tied to ONE implementation. Suppose we could increase (...) (22 years ago, 3-Jan-03, to lugnet.cad)

(...) You don't actually have to draw them last. Just offset them in the Z buffer a bit toward the camera. It's cheap, and fast, and I think it looks pretty good. Opengl does it for you with glPolygonOffset but you can examine some homemade code (...) (22 years ago, 3-Jan-03, to lugnet.cad)

(...) In parts like 2431p02 2431p51 2431bp52 And perhaps more parts, have lines around the pattern polygons. The polygons on these parts seem large enough to me that the lines in these cases are not required for Lars' explanation. (I'll convert (...) (22 years ago, 4-Jan-03, to lugnet.cad)

(...) You'll have to ask the authors then. I think you should delete the lines. So, have you thought about a new META? /Lars (22 years ago, 4-Jan-03, to lugnet.cad)

(...) Not yet, What is the oppinion of the viewer-builders? They have to include the new META in their software (or not). Niels (22 years ago, 5-Jan-03, to lugnet.cad)
