[Plib-devel] Importers/Exporters

[Wolfram K. <w_...@rz...>]

Hi,

I tested some importers and exporters.
I used three files with 36000, 18000 and 550 polygons.
*.3ds loader: crashes with the two larger files, loads the small file
ok. The colours of the small object seemed wrong.
*.3ds writer: Polytrans says about the object:
not 3ds file or version not recognized.
However, we don't have the newest PolyTrans.
*.dxf loader: Always reads exactly one triangle :-).
*.dxf writer: Polytrans thought, it would be an ASCII file, which it
wasn't.
*.obj loader: works, hallelujah!
*.obj writer: Polytrans says:
password for encrypted file xxxx is wrong. Import aborted
VRML import: crashes on all three files, both VRML1.0 and VRML 2.0. 

BTW, when I "save as" and give a nonsense extension, like "hhh", there
is no warning. This is quite dangerous, since you think, plib can
write wrl etc.

Besides these three objects, I tried two *.dxf files. Both loaded, but
all polygons were converted into triangles by ignoring the rest of the
vertices, so one quad became one triangle. In one of the files, there
was also a nonsense triangle, probably with wrong vertex coordinates.

Lastly, I tested a simple textured box. I wasn't able to load it
textured into PPE with any format. That maybe due to problems with
either polytrans or the texture-path or the texture-format, or maybe
with the file loaders.

*.3ds crashed. *.wrl loaded something, but it wasn't even a box.
*.obj worked, apart from the missing texture. *.dxf gave the by now
familiar triangle.

Bye bye,
Wolfram Kuss.
