[Meshlab-devel] collada issues identified

[skunkwerk <sku...@gm...>]

Guido, hope you can give me some feedback on these issues once you're done
with your paper.

I've identified the source of two problems with the collada importer:

1)  for some models (typically cars) the collada file will specify the
geometry for one wheel, and have all four wheels as instances of that one
wheel specified by transformation matrices.  the collada plugin doesn't seem
to parse these, however, and as a result the wheel shows up once in the
bottom center of the model (see sample file here: www.akbars.net/car.dae.zip
)

2) for some models, the geometry was being imported, and meshlab was loading
the texture files, but they weren't being mapped to the model (faces had no
textures - which I confirmed with the info tool reporting the face ids were
-1).  I believe this is due to the importer not parsing <library_nodes>
nodes, as when I move these same nodes to
<library_visual_scenes><visual_scene> the textures show up correctly.  I'll
try working on a fix for this.

thanks,
imran
