(...) MLCad keyboard controls are not supported since the user interface is totally different and parts are by far much more easy to place and connect MPD saving is not supported, but .L3B format is compatible with .LDR except for some metacommand (...) (16 years ago, 10-Dec-08, to lugnet.cad)

(...) Oooo! What fun! Thanks for sharing this. I must admit, I miss the advent calendars like this, with simple pieces because I used to enjoy designing alternate models as the days went on. Remember 1998's set 1298? wow. ten years ago now: (URL) (16 years ago, 11-Dec-08, to lugnet.cad)

I've been working on honing my skills at the whole rendering thing using many of the tools written by members of this forum and with knowledge gleaned here. I thought it was time to share! I asked my kids which model they would like me to use for a (...) (16 years ago, 10-Dec-08, to lugnet.cad, FTX)

(...) It depends on what your threshold is but taking the difference (as you do in a cross product) of two big numbers is less accurate (very much so sometimes) than taking the difference of two smaller numbers. Even without this issue it means that (...) (16 years ago, 9-Dec-08, to lugnet.cad)

(...) No, I just take the cross product, and if the length (squared) is 0, I give an error. I don't see how normalizing the length of the two vectors that I feed into the cross product would improve things much here. Sure, it might mean that my (...) (16 years ago, 9-Dec-08, to lugnet.cad)

(...) Wow! Very impressive! I will definitely have to try it out. A couple of questions: are MLCAD's keyboard controls supported? Can I export back into LDR/MPD format? What does the model tree look like? -Mike (16 years ago, 9-Dec-08, to lugnet.cad)

--snip-- (...) I assume that you divide by the vector lengths first (as in normalise them before taking the cross-product) but if you don't then you should. Tim (16 years ago, 9-Dec-08, to lugnet.cad)

(...) If they're on a curved surface, you'll get higher quality out of LDView half the time if you split them into triangles. (I say half the time, because OpenGL splits them into triangles in order to render them, and half the time they'll be split (...) (16 years ago, 9-Dec-08, to lugnet.cad)

(...) As far as I can see the threshold is the number of digits that are used to determine wheather a value is the same as the other. So if you use 6.0 and 6.0001 with a threshold of 0.0001 the value are interpreted to be the same. That makes sense (...) (16 years ago, 9-Dec-08, to lugnet.cad)
