Collada file doesn't work?


I have got a collada file, that includes the vertices,normals and the color-array. Now I would like to see the data as an graph but nothing appears on my screen. (I’am using Blender to display the dae file)

This is my library_geometries:

The vertices were given and using them I have generated the appropriate normals in Java3d (normalGenerator)
In my opinion the p-element or the generated normals are wrong but I don’t know why.
Do you know what’s the problem?

Many thanks in advance

Another question:
Is it possible to check that my normals are correct?

I also come across the same problem.Waiting for the meaningfuol reply

I’ve got an additional Question.
I’m writing a COLLADA-Exporter in Java and want to create geometries by using only coordinates from 3d-points.
How do I know, which Points create one triangle? Is there any opportunity to triangulate my points?

This has been posted for quite some time and with no response. I am interested in seeing if the generated normal are wrong? Thank you.
