Do you mind sharing the STL files as well?
I don't render with POV and would like to import the bricks into Blender or Cinema 4D.


Re: New Parts for LGEO Library - Damien Roux - 2015-05-27

Unfortunately, I only use STL format to go from native CATIA format to PovRay. I don't keep the STL files, only the CATIA ones.

I can give you a few parts if you want some, but I will not release them all. It's too much work.
Also I don't model studs and understuds so the parts won't even be complete in STL.

But I can fulfill a few requests if needed.

Maybe you can also write some code to convert Pov geometry to a Blender readable format or use some kind of utility.


Re: New Parts for LGEO Library - Gerhard - 2015-05-28

According to the FAQ at povray.org converting POV to something else is not feasible/possible.

I'm working on an importer for Cinema 4D and don't want to create the meshes on the fly but rather import them from an external library to use also meshes with higher resolution.

I would appreciate to get some samples from you to test the import.
Just some basic bricks and perhaps some more sophisticated ones would be great.

To update my feedback on your parts:

Every part released so far works fine. Just one minor issue easily corrected: no reference to part 4162p0l in the LGEO.xml file you provided.


Re: New Parts for LGEO Library - Damien Roux - 2015-05-28

Thanks for feedback, I've corrected the LGEO.xml file.


Re: New Parts for LGEO Library - Damien Roux - 2015-05-28

I've shared the 2998 part STL file : here. You can have a try.


I know PovRay scenes are quite impossible to convert in another format, but I'm pretty sure it can easily be done for my STL PovRay files. They are only made of smooth_triangles, nothing really complicated to convert to another mesh format, I think.

Re: New Parts for LGEO Library - Gerhard - 2015-05-29

You are right, I was't aware that PoseRay can convert also to OBJ.
I was able to batch convert 354 of your files back to OBJ and after some vertex optimization I got almost the same result like your provided reference STL.
Thanks a lot, they are of incredible quality.


Re: New Parts for LGEO Library - Damien Roux - 2015-05-29

Great!


Re: New Parts for LGEO Library - Christophe Mitillo - 2015-06-04

Hi Damien,

I'm still amazed on how detailed your parts are. If you don't mind, I have a couple of question regarding your library.

I see that you convert your parts from CATIA to Povray using STL2pov. I tried myself using the converter a few years ago after designing my own hires parts with Solidworks. Although I had no issues when converting to simple triangles, the conversion to smooth triangles always messed up the result giving misoriented polygons. Curiously the result was part triangles and part smooth triangles.
How do you process your parts prior to conversion to have only smooth triangles ?
Regarding your printed parts, I'm curious about the way you convert flat 2D patterns to 3D objects. Is it automated or do you process each pattern manually ?
