New Parts for LGEO Library

[Christophe Mitillo]

Thanks for anwsering my questions.

For STL conversion, after deep investigation and a few tests, I think that maybe the problem is in STL2pov. I use version 2.5 of the software.

For testing purpose, I used it on the STL file for part 2998 you shared with Gerhart afew days ago. The converted .inc file is messed up like mines.
Looking at the files precisely, that's what I found. The flat triangles seem to be converted like yours, but the smoothed ones are different.

in your .inc part (converted with STL2pov 2.4.4):

triangle { // #670
<16, -48.2614, -1.51945>,
<16, -48.0893, -2.26346>,
<16, -54.537, -2.62187>
}
smooth_triangle { // #671
<16, -54.4251, -4.3668>, <-0.998433, 0.00455732, 0.0557737>,
<16, -54.537, -2.62187>, <-1, 0, 0>,
<16, -48.0893, -2.26346>, <-1, 0, 0>
}

in my conversion with STL2pov 2.5:

triangle { // #670
<16, -48.2614, -1.51945>,
<16, -48.0893, -2.26346>,
<16, -54.537, -2.62187>
}
smooth_triangle { // #671
<-54.4251, 16, -4.3668>, <0.00455732, -0.998433, 0.0557737>,
<-54.537, 16, -2.62187>, <0, -1, 0>,
<-48.0893, 16, -2.26346>, <0, -1, 0>
}
as you can see, in the smoothed triangle, plans X an Y are switched, causing a 90° rotation. All others are rotated also.

Unfortunately, I'm in a dead end as STL2pov 2.4.4 it's not available now.
Do you mind in sharing with me your version of STL2pov so I can fulfill my tests ?
