Wireframe material connects faces!?

[mmmmm]

I have a material using "polygon_mode wireframe".

This works, but ogre connects polygons it should not connect:

Wireframe - This is how it looks (error)

Here is how the faces look like (the planes are only single sided)

Original geometry

How meshy renders it correctly:

Meshy renders it corrently

I tried to open the mesh with meshy and there it works fine. Any recommendations?
I am using Ogre 1.10 for iOS and WebGL.

Thanks for your help!

the solution:
http://codeflow.org/entries/2012/aug/02 ... ordinates/

however it is (obviously) not implemented as doing so is not trivial:
1. either the RTSS needs to emit a geometry shader that computes the barycentric coordinates (requires GLES3.2, the RTSS does not support geometry shaders right now)
2. or the RTSS needs to compute barycentric coordinates on the CPU and add them as a VBO to the mesh. (no support in RTSS for such things exits either)

the easiest path is probably to write your own custom shader and manually compute the barycentric coord VBO.
