I just got another email discussing the use of orthographic camera and building instructions. The two do not work well together, and won't for the forseeable future. LPub leaves it to L3P to determine the camera settings. For a given LDraw file, (...) (22 years ago, 22-Dec-02, to lugnet.cad, lugnet.inst)

(...) Yes, I plan adding -co for orthographic camera with automatic camera positioning. But the orthographic camera has changed in PovRay 3.5, and it is playing games with me. Perhaps I'll use the command "version 3.0" to overcome my trouble... (...) (22 years ago, 23-Dec-02, to lugnet.cad, lugnet.inst)

I ran into the want for orthographic camera, with my pneumatic adding machine MOC, and made some discoveries. You can simulate orthographic images with a camera angle of 1. I tried using 0, but L3P silently ignores this and assumes you want the (...) (22 years ago, 5-Jan-03, to lugnet.cad, lugnet.inst)

So to clarify, rather than use the ortho setting, you are choosing the camera angle setting and using a 1? Is that it, or are you doing additional stuff? I was playing around last night and was noticing that the creations weren't always centered (...) (22 years ago, 5-Jan-03, to lugnet.cad, lugnet.inst)

Hi Jake, (...) I'm merely setting the camera angle to 1 which eliminates perspective. I do not set orthographic. I modified LPub so the lowest camera angle is 1, and fixed the label that indicates the actual camera angle so it is updated as the (...) (22 years ago, 5-Jan-03, to lugnet.cad, lugnet.inst)

(...) L3P can perform automatic camera positioning only when you use -cg<la>,<lo>[,<r>] camera globe position, default is 30,45,0 and radius is <= 0. -ca<a> is allowed too. Otherwise you have constrained the camera too much. /Lars (22 years ago, 5-Jan-03, to lugnet.cad, lugnet.inst)

LPub uses: -cg0,0 -ca30 by default. LPub controls view angle by rotating all the parts to match rotation step specification and view coordinates. It seems like this qualifies as auto-centerable, but it does not always work. Kevin (...) (22 years ago, 5-Jan-03, to lugnet.cad, lugnet.inst)
